Page 73 • Other topics about Setting Measurement Conditions Overview The E5071C allows you to use up to 160 channels (when the number of traces is up to 9) to perform measurement under 160 different stimulus conditions. For each channel, up to 4, 6, 9, 12 or 16 traces (measurement parameters) can be displayed.
Page 74 Measurement 1601 You may want to select the "1- channel, 4- trace" or "2- channel, 4- trace" configuration to save the time required to save/recall the instrument state file, since this takes longer with other configurations. More channels and traces requires longer measurement time.

Page 76 Measurement setting of the window layout determines the number of channels displayed on screen. The execution of measurement for each channel does not • depend on how the channel is displayed (channels that are not displayed can be measured). For information on executing measurement for each channel (trigger mode and trigger source), refer to Making Measurements.
Page 77 E5071C From Firmware revision A.08.10, channel display configuration of 8×9, 6×12 and 8×12 is added.

The E5071C uses the following adapter removal process to remove adapter characteristics: 1. Perform calibration with the adapter in use.
Page 225 This above described method also makes it possible to add adapter characteristics to a port with n-port full calibration. This allows you to make a measurement with the adapter. E5071C uses the following adapter insertion process to insert adapter characteristics: 1.

Page 234 Measurement Unknown Thru Calibration Overview • Procedure • Other topics about Advanced Calibration Overview Unknown Thru Cal is the preferred THRU method of calibrating the ENA to measure a non-insertable device. The major benefits of using a unknown Thru calibration are: It is easy to perform.
Page 235 E5071C The electrical delay is automatically measured and can be confirmed. Press > Port Extensions > Extension Port 1 {Value} 4. If there is an offset in the short circuit used to terminate the Unknown Thru standard, remember to subtract its electrical length from the measurement result.
Page 236 Procedure Turning off the "System Calibration" In its default setting, the E5071C applies "system calibration" to the measured S-parameter data. Because the "system calibration" is applied only to the S-parameter measurement data and NOT to the absolute value measurement data, it interferes with 8-term error model calibration when calculating error coefficients on external computer.
Page 237 Set the "RF ranging mode" to MANual (3 GHz, 4.5 GHz, 6.5 GHz and 8.5 GHz option only) There is a hardware function called "RF ranging mode" on E5071C. The default setting of this state is AUTO, and this state interferes with 8-term error model calibration when calculating error coefficients on external computer.
Page 238 Since the "RF ranging" is hold during the measurement, the • system dynamic range of the E5071C will degrade by 6dB, as a result of the 8-term calibration performed externally. However, there is NO dynamic range degrade by 8-term error model calibration with internal calibration of the ENA.
Page 239 • Other topics about Mixer Calibration Overview The E5071C has a scalar-mixer calibration function for measuring frequency conversion devices. Scalar-mixer calibration allows you to measure the magnitude value and reflection parameter of the mixer's conversion loss with very high accuracy by performing calibration using calibration standards (OPEN/SHORT/LOAD) in combination as well as a power meter.
Page 240 Measurement be divided into two types of errors: one associated with the stimulus side at the input frequencies and the other associated with the response side at the output frequencies. As previously discussed, calculating the transmission tracking (ETF) based on both stimulus and response sides is the key to using error correction during frequency-offset measurements.

Page 242 Measurement 6. For the scalar-mixer calibration, only one direction with 2-ports calibration is available. "One direction" means the forward or reverse direction. Two directions may be used among the same ports, but this would not be full 2-port scalar-mixer calibration but simply the simultaneous operation of single-direction scalar- mixer calibrations..

Page 625: System Verification
A network analyzer measurement “system” includes the analyzer, calibration kit, test cables, and any necessary adapters. The system verification software in the E5071C is used to verify the system’s conformance to the “system” specifications. A “pass” result demonstrates that the analyzer, test cables, and adapters, perform correctly as a system.

Page 628 ** The supported connector type is "male-female". Cable Substitution The test port cables specified for the E5071C have been characterized for connector repeatability, magnitude and phase stability with flexing, return loss, insertion loss, and aging rate. Since test port cable performance is a significant contributor to the system performance, cables of lower performance will increase the uncertainty of your measurement.
Page 629 E5071C Flex Factor determines how much of the cable phase uncertainty to include in determining the limit lines. Set to 0% (zero) if the cables are held down in a fixture and are not allowed to move during the calibration and verification.

Page 660: System Description
A network analyzer supplies a sweep signal to a DUT, measures its transmission and reflection, and displays the results as ratios against the input signal from the signal source. The E5071C network analyzer consists of the circuit modules shown in the following figure.
Page 661 E5071C Source Switcher The source switcher is used to switch test ports to which the RF signal is supplied from the source. Signal Separator The signal separator consists of directivity couplers that detect input and output signals at the test ports. On a test port to which a signal is output, the output signal and the reflection from the DUT are detected as the reference signal (R) and the test signal (T), respectively.

Page 761 Remote Mode • Other topics about Overview Type and Structure of Commands The SCPI commands available for the E5071C are classified into 2 groups as follows. E5071C commands Commands specific to the E5071C. They cover all measurement functions that the E5071C has and some general-purpose functions. The commands in this group are arranged in a hierarchical structure called the command tree.
Page 762 Programming The following figure shows an example of how to use colons and semicolons to efficiently access commands in the command tree. Using colons and semicolons Grammar of Messages This section describes the grammar to send program messages via GPIB. Program messages are messages that the user sends to the instrument from the external controller to control the instrument.
Page 763 HTBasic. OUTPUT 717;"*CLS;:STAT:PRES" Remote Mode The E5071C does not provide remote mode. Therefore, even if you send a GPIB command, it never enters into remote mode automatically. There is no local key to release remote mode. If you need to prevent misoperation during remote control due to entry from the front panel or mouse, lock the input devices using the following commands.
Page 764 • Checking LXI Compliance The E5071C having LXI compliance will show a LXI logo at the start up screen of the firmware . If this logo does not appears at the start up screen of the firmware, it means that the system is not LXI-C complaint.

Page 929 E5071C Preventing Erroneous Key Operation on the Front Panel (key lock feature) When no operation is required from the front panel controls, the mouse, or the keyboard, disabling these input devices can prevent any erroneous operation that might be caused by accidentally touching the devices.
Page 930 (for example, reading out traces for each measurement). With the E5071C, the processing time for SCPI commands can be improved by decreasing the refresh rate of the LCD display. Measurement results (trace) do not need to be updated When the measurement trace does not need to be updated, turn off the updating of the LCD display.
Page 931 *ESE Follow these steps: 1. Set the E5071C so that it generates an SRQ when any of the error occurrence bits is set to 1 in the standard event status register. 2. When an SRQ is generated, the program interrupts the measurement cycle.
Page 932 Programming Using Error Queue An error queue holds the number for the error and the error message. Reading the error queue allows the user to verify the error that has occurred. To retrieve the content of an error queue, use the following command: :SYST:ERR? The error queue can be used in the following ways:...
