Page 26 Internal and External. In Internal Automatic Control mode the Test Set’s operation is controlled by an application program running on the built-in IBASIC Controller. In External Automatic Control mode the Test Set’s operation is controlled by an external controller connected to the Test Set through the HP-IB interface.
Page 27 An HP-IB/RS-232/Parallel Printer interface capability is available in the Test Set. In Manual Control mode this provides the capability of connecting an external HP-IB, serial, or parallel printer to the Test Set so that display screens can be printed.
Page 28 Controller when an IBASIC program is running. These include the serial interface at select code 9, the HP-IB interface at select code 7, the parallel printer interface at select code 15, and the CRT. In Manual Control mode, front panel information (instrument settings, measurement results, data input from the DUT) is routed to the CRT through the To Screen control hardware.
Page 29 IBASIC programs to run on the internal IBASIC Controller are discussed in this manual. Secondly, the IBASIC Controller has a dedicated HP-IB interface, select code 8 in , for communicating with the internal instruments of the Test Set. This figure 2 HP-IB interface is only available to the IBASIC Controller.
Page 30 External Automatic Control Mode In External Automatic Control mode the Test Set’s operation is controlled by an external controller connected to the Test Set through the HP-IB interface. When in External Automatic Control mode the Test Set’s internal configuration is the same as in Manual Control Mode with two exceptions: 1.
Page 31 Chapter 1, Using HP-IB Overview of the Test Set Writing programs for the Test Set One of the design goals for automatic control of the Test Set was that it operate the same way programmatically as it does manually. This is a key point to remember when developing programs for the Test Set.

Page 38 However, if a previous program has set the state to OFF, the measurement will not be available. Attempting to read from a measurement field that is not in the ON state will cause HP-IB Error:-420 Query UNTERMINATED. 6. If the trigger mode has been changed, trigger a reading.
Page 39 Chapter 1, Using HP-IB Getting Started 7. Send the MEASure query command to initiate a reading. This will place the measured value into the Test Set’s Output Queue. NOTE: When making AF Analyzer SINAD, Distortion, Signal to Noise Ratio, AF Frequency, DC Level, or Current measurements, the measurement type must first be selected using the SELect command.
Page 40 Chapter 1, Using HP-IB Getting Started • Guideline #3. Avoid program hangs. If the program stops or “hangs up” when trying to ENTER a measured value, it is most likely that the desired measurement field is not available. There are several reasons that can happen: 1.
Page 41 Chapter 1, Using HP-IB Getting Started • Guideline #4. Use single quotes and spaces properly. The syntax diagrams in chapter 4, "HP-IB Commands," show where single quotes are needed and where spaces are needed. Example OUTPUT 714;"DISP<space>AFAN" OUTPUT 714;"AFAN:DEMP<space>’Off’" Improper use of single quotes and spaces will cause, HP-IB Error:-103 Invalid Separator •...
Page 42 For example, if the Test Set’s front panel is displaying TX Frequency as 835.02 MHz, and the field is queried through HP-IB, the value returned will be 835020000 since the HP-IB Units for frequency are Hz. Note that changing Display Units will not change HP-IB Units or Attribute Units.
Page 43 Getting Started Preparing the Test Set For HP-IB Use 1. If other HP-IB devices are in the system, attach an HP-IB cable from the Test Set’s rear- panel HP-IB connector to any one of the other devices in the test system.
Page 44 Getting Started Using the HP-IB with the Test Set’s built-in IBASIC Controller The Test Set has two HP-IB interfaces, an internal-only HP-IB at select code 8 and an external HP-IB at select code 7 . The HP-IB at select code 8 is only available to the built-in IBASIC Controller and is used exclusively for communication between the IBASIC Controller and the Test Set.
Page 45 Chapter 4, "HP-IB Commands" The bus address 714 used in the following BASIC language examples assumes an HP-IB interface at select code 7, and a Test Set HP-IB address of 14. All examples assume an external controller is being used.

Page 58 Chapter 2, Methods For Reading Measurement Results Background Background One of the most common remote user interface operations performed on an Test Set is to query and read a measurement result. Generally, this operation is accomplished by sending the query command to the Test Set, followed immediately by a request to read the requested measurement result.
Page 59 Chapter 2, Methods For Reading Measurement Results Background This situation can be avoided entirely by: 1. sending a Selected Device Clear (SDC) interface message to put the Test Set’s HP-IB subsystem into a known state. 2. sending a command to terminate the requested measurement cycle.

Page 63 The following lines of code handle the case where the request for a measurement result has timed out. Set up a timeout for any I/O activity on the HP-IB while the control program is trying to regain control of the Test Set. This will allow the function to gracefully stop program execution if the control program cannot regain control of the Test Set.
Page 64 Status Byte to determine when there is data in the Output Queue. A polling loop is used to query the Status byte. The timeout duration for returning the measurement result is handled by the polling loop. An HP-IB interface activity timeout is also set up to handle time-outs resulting from problems with the HP-IB interface.

Page 70 The process of executing a command can be divided into three steps: 1. Command is accepted from HP-IB and checked for proper structure and parameters. 2. Commands is sent to instrument hardware. 3. Instrument hardware fully responds after some time, ∆t.
Page 71 Chapter 3, HP-IB Command Guidelines Guidelines for Operation Guidelines for Operation The following topics discuss rules and guidelines for controlling the Test Set through HP-IB. Command Names All command names of more than four characters have an alternate abbreviated form using only upper case letters and, in some cases, a single numeral. The commands are not case sensitive.

Page 73 Chapter 3, HP-IB Command Guidelines Guidelines for Operation Using Colons to Separate Commands The HP-IB command syntax is structured using a control hierarchy that is analogous to manual operation. The control hierarchy for making a manual instrument setting using the front- panel controls is as follows: first the screen is accessed, then the desired field is selected, then the appropriate setting is made.
Page 74 Guidelines for Operation Using the Semicolon and Colon to Output Multiple Commands A semicolon followed by a colon (;:) tells the HP-IB command parser that the next command is at the top level of the command hierarchy. This allows commands from different instruments to be output on one command line.
Page 75 NOTE: When querying measurements or settings through HP-IB, the Test Set always returns numeric values in HP-IB Units or Attribute Units, regardless of the current Display Units setting. Refer "HP-IB Units (UNITs)" on page 78 "Attribute Units (AUNits)" on page 81 further information.

Page 78 Chapter 3, HP-IB Command Guidelines Guidelines for Operation HP-IB Units (UNITs) HP-IB Units are the units-of-measure used by the Test Set when sending numeric data (field settings and measurement results) through HP-IB, and the default units-of-measure for receiving numeric data (field settings and measurement results) through HP-IB.

Only the HP-IB units for power, relative level, and frequency error can be changed. lists the Table 9 measurement and instrument setup fields which have changeable HP-IB Units.
Page 80 For example, if the command RFG:FREQ 900 is sent through HP-IB, the Test Set will interpret the data as 900 Hz, since HZ is the HP-IB Unit for frequency. This would result in an Input value out of range error. Sending the command RFG:FREQ 900 MHZ would set the value to 900 MHz.
Page 81 Data Function keys: REF SET, METER, HI LIMIT and LO LIMIT respectively. Attribute Units use the same set of units-of-measure as the HP-IB Units (except Frequency Error), but are only used with the MEASure commands: REFerence, METer (HEND, LEND, INT), HLIMit and LLIMit.

Page 87 When querying measurement functions REFerence, METer, HLIMit and LLIMit through HP-IB, the Test Set always returns numeric values in Attribute Units, regardless of the current Display Units or HP-IB Units settings. Numeric values are expressed in scientific notation. For example, if the REF SET measurement function is displayed as 25% on the Test Set, the value returned through HP-IB is +2.50000000E+001 (2.5×10...

Page 210: Ieee 488.2 Common Commands
IEEE 488.2 Common Commands The IEEE 488.2 Standard defines a set of common commands which provide for uniform communication between devices on the HP-IB. These commands are common to all instruments which comply with the IEEE 488.2 Standard. These commands control some of the basic instrument functions, such as instrument identification, instrument reset, and instrument status reporting.
Page 211: Common Command Descriptions
Common Command Descriptions Common Command Descriptions *IDN? (Identification Query) The *IDN? query causes a device to send its identification information over the bus. The Test Set responds to the *IDN? command by placing its identification information, in ASCII format, into the Output Queue. The response data is obtained by reading the Output Queue into a string variable of length 72.

Page 230: Triggering Measurements

Page 231 Triggering Measurements Trigger Modes The Trigger Mode is defined by two parameters: retriggering and settling. Retriggering Retriggering refers to what a measurement does once it has completed a measurement cycle. There are two options: 1. Single retriggering causes the measurement cycle to stop once a valid measurement result has been obtained.
Page 232 This is true for both retriggering modes. This has the consequence that both the HP-IB bus and the Active Controller handshake are in a temporary holdoff state while the Active Controller waits to read the measurement result from the Test Set.
Page 233 :RETR REP then a new measurement cycle is started and measurement results will be available for all active measurements when valid results have been obtained. If the HP-IB trigger mode is :RETR SING then a measurement cycle must be started by issuing a trigger event. Refer to "Triggering Measurements"...
Page 234 :ABORt The :ABORt command tells the Test Set to stop a currently executing measurement cycle and get ready for a new HP-IB command. If for any reason a valid measurement cannot be made, this command allows the control program to terminate the requested measurement and regain control of the Test Set.

Page 236 Triggering Measurements Trigger Mode and Measurement Speed There are two generalized scenarios which can be described for HP-IB triggering control. The first is to have the Test Set return measurement results as fast as possible and assume that the control program will handle all transient settling and value tolerance activities.
Page 237 (an external trigger is detected) or until the measurement trigger is aborted. This is true for both retriggering modes. This has the consequence that both the HP-IB bus and the Active Controller handshake are in a temporary holdoff state while the Active Controller waits to read the measurement result from the Test Set.

Page 240: Increasing Measurement Throughput
Chapter 5, Advanced Operations Increasing Measurement Throughput Increasing Measurement Throughput Measurement throughput is defined as the number of measurements made per unit of time. When operating the Test Set in the Internal or External Automatic Control Mode, measurement throughput is influenced by measurement speed, measurement setup time, and execution speed of the control program.
Page 241 Chapter 5, Advanced Operations Increasing Measurement Throughput Time-to-first-reading after making new settings is usually much slower than the repetitive reading rate once the first reading has been returned. The main contributor to first-reading measurement time is hardware autoranging. Hardware autoranging time can be eliminated by first establishing the expected AF and RF signal levels into the Test Set.
Page 242 Chapter 5, Advanced Operations Increasing Measurement Throughput 3. Frequency Counter Gate Time The frequency counter’s gate time specifies how long the RF or AF frequency counter samples the signal before displaying the measured result. Short gate times measure instantaneous frequency and long gate times measure average frequency. The longer the gate time, the longer the measurement cycle.
Page 243 2. Define a base instrument state and then modify it as needed for each measurement (always returning to the base state after finishing the measurement). Defining a base instrument state requires fewer HP-IB transactions to set up an instrument (in the majority of cases) which in turn reduces measurement setup...
Page 244 Execution speed of the control program is defined as the time required to execute a given number of program lines. . Each time the HP-IB is accessed, a given amount of time is required to configure the devices on the bus for data transfer. Every time a BASIC or IBASIC OUTPUT or ENTER statement is executed this bus configuration time is incurred.
Page 245 The ;: (semicolon-colon) separator tells the The ;: (semicolon-colon) Separator. Test Set’s HP-IB command parser that the next command is at the top level of the command hierarchy.

Page 252 Chapter 5, Advanced Operations Status Reporting Status Register Structure Overview The structure of the register groups used in the Test Set is based upon the status data structures outlined in the IEEE 488 and SCPI 1994.0 Standards. There are two types of status data structures used in the Test Set: status registers and status queues.
Page 253 A condition is a Test Set state that is either TRUE or FALSE Condition Register. (an HP-IB command error has occurred or an HP-IB command error has not occurred). Each bit in a Condition Register is assigned to a particular Test Set state.
Page 254 Chapter 5, Advanced Operations Status Reporting Transition Filters are read-write. Transition Filters are unaffected by a *CLS (clear status) command or queries. The Transitions Filters are set to pass positive transitions (PTR) at power on and after receiving the *RST (reset) command (all 16 bits of the PTR register set to 1 and all 16 bits of the NTR register set to 0).
Page 255 Chapter 5, Advanced Operations Status Reporting Status Reporting Structure Operation. In general the status reporting structure described on the previous pages is used as follows: • Determine which conditions, as defined by their bit positions in the Condition Register, should cause the Summary Message to be set TRUE if they occur.

The Output Queue Group includes a FIFO queue and a Message Available (MAV) Summary Message.
Page 269 (as is the case with some Signaling Decoder measurements). Care should be exercised when reading the Output Queue since the HP-IB bus will, by design, wait until the data is available before processing further bus messages.

Page 297: Hp-Ib Service Requests
Chapter 5, Advanced Operations HP-IB Service Requests HP-IB Service Requests The Test Set is capable of generating a “service request” when it requires the Active Controller to take action. Service requests are generally made after the Test Set has completed a task (such as making a measurement) or when an error condition exists (such as an internal self-calibration has failed).
Page 298 When an enabled service request condition exists, the Test Set sends the Service Request message (SRQ) on the HP-IB bus and reports that it has requested service by setting the Request Service (RQS) bit in the Status Byte register to the TRUE, logic 1, state.
Page 299 Chapter 5, Advanced Operations HP-IB Service Requests Service Request Enable Register Service request enabling allows the application programmer to select which Summary Messages in the Status Byte Register may cause a service request. The Service Request Enable Register, illustrated in...
Page 300 0-5 and 7 of the Status Byte Register, will generate a Service Request on the HP-IB bus. The Test Set always ignores bit 6 (binary weight 64) of the bit pattern set by the *SRE command.
Page 301 The decimal value of the bit pattern must be a positive integer in the range of 0 to 255. Sending a negative number or a number greater than 255 causes an HP-IB Error: -222 Data out of range. Clearing the Service Request Enable Register The Service Request Enable Register is cleared by sending the *SRE Common Command with a decimal value of zero.

This procedure does not include instructions for setting up the Active Controller to respond to the Service Request message generated by the Test Set.

Chapter 7, IBASIC Controller PROGram Subsystem PROGram Subsystem Introduction The PROGram Subsystem provides a set of commands which allow an external controller to generate and control an IBASIC program within the Test Set. The PROGram Subsystem in the Test Set is a limited implementation of the PROGram Subsystem defined in the Standard Commands for Programmable Instruments (SCPI) Standard.
Page 411 Chapter 7, IBASIC Controller PROGram Subsystem SCPI PROGram Subsystem The SCPI PROGram Subsystem was designed to support instruments which can store multiple programs in RAM memory at the same time. The SCPI PROGram Subsystem provides commands which allow multiple programs to be named, defined and resident in the instrument at the same time.

The name of this file is preceded by a lower case c in the Test Set. This tells the TESTS Subsystem that this particular file contains program code.
Page 440 Chapter 7, IBASIC Controller The TESTS Subsystem Procedure Files A Procedure allows the user to define which of the test subroutines, parameters, and specifications defined in the Library will be used to test a specific Radio. There may be many Procedures defined that use the same IBASIC Code and Library, each using a different subset of the choices available in the Library.

Page 545: Example Programs
This section contains two example programs for controlling the Call Processing Subsystem. The SRQ Example Program demonstrates how to control program flow using the service request feature of the HP-IB. The Polling Example Program demonstrates how to control program flow by polling the Test Set’s status registers.
Page 546 Chapter 8, Programming The Call Processing Subsystem Example Programs The program traps any errors which may occur while executing. If an error is detected, the error data is printed and the program stops. In a ‘real world’ environment the control program would have to make some flow decision based upon the nature of the error.
