- Page 5 The output pulse width is variable from 8 to 100 ns, and rise time is fixed at less than 200 ps. The AVMP-3-B-P-OT-ELA-R5 is a highly flexible instrument. Aside from the internal trigger source, it can also be triggered or gated by external TTL-level signals. A front- panel pushbutton or a computer command can also be used to trigger the instrument.

- Page 7 This instrument is exempt from Directive 2002/95/EC of the European Parliament and of the Council of 27 January 2003 on the Restriction of the use of certain Hazardous Substances (RoHS) in electrical and electronic equipment. Specifically, Avtech instruments are considered "Monitoring and control instruments" (Category 9) as defined in Annex 1A of Directive 2002/96/EC.
- Page 8 INSTALLATION VISUAL CHECK After unpacking the instrument, examine to ensure that it has not been damaged in shipment. Visually inspect all connectors, knobs, liquid crystal displays (LCDs), and the handles. Confirm that a power cord, a GPIB cable, and two instrumentation manuals (this manual and the “Programming Manual for -B Instruments”) are with the instrument.
- Page 9 5. Do not attempt any repairs on the instrument, beyond the fuse replacement procedures described in this manual. Contact Avtech technical support (see page 2 for contact information) if the instrument requires servicing. Service is to be performed solely by qualified service personnel.

LABVIEW DRIVERS A LabVIEW driver for this instrument is available for download on the Avtech web site, at http://www.avtechpulse.com/labview. A copy is also available in National Instruments' Instrument Driver Library at http://www.natinst.com/.
- Page 11 FUSES This instrument contains four fuses. All are accessible from the rear-panel. Two protect the AC prime power input, and two protect the internal DC power supplies. The locations of the fuses on the rear panel are shown in the figure below: Fuses #1 and #2 Fuse #4 Fuse #3...
- Page 12 DC FUSE REPLACEMENT The DC fuses may be replaced by inserting the tip of a flat-head screwdriver into the fuse holder slot, and rotating the slot counter-clockwise. The fuse and its carrier will then pop out. FUSE RATINGS The following table lists the required fuses: Nominal Manufacturer’s Distributor’s...
- Page 13 FRONT PANEL CONTROLS 1. POWER Switch . This is the main power switch. When turning the instrument on, there may be a delay of several seconds before the instrument appears to respond. 2. OVERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation.
- Page 14 6. KEYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten.
- Page 15 REAR PANEL CONTROLS GATE TRIG RS-232 GPIB 1. AC POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. One end of the detachable power cord that is supplied with the instrument plugs into this socket. 2.
- Page 16 6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on GPIB control. 7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be attached to this connector to allow the instrument to be computer-controlled.
- Page 17 GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. OUT. This is the main output. ...

- Page 19 If amplitudes less than 1/3 of the full-scale value are desired, better results will be obtained if the pulse generator is operated at a higher amplitude, and an attenuator is connected to the output. Avtech recommends the ATT-0444-XX-SMA-02 series of 18 GHz coaxial attenuators from Midwest Microwave, http://www.midwestmicrowave.com/.
- Page 20 PROTECTING YOUR INSTRUMENT DO NOT EXCEED 1 MHz The output stage may be damaged if triggered by an external signal at a pulse repetition frequency greater than 1 MHz. USE A 50 OHM LOAD The output stage may be damaged if the output is not terminated into a 50Ω load.

- Page 23 a) Press the MOVE button until the arrow pointer is pointing at the output menu item. b) Press the CHANGE button. The output submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “ON” choice. d) Press CHANGE to return to the main menu. 8.
- Page 24 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “OP1B Interface Programming Manual” describes in detail how to connect the pulse generator to your computer, and the programming commands themselves. A large number of commands are available; however, normally you will only need a few of these.
- Page 25 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available commands is given below. These commands are described in detail in the “OP1B Interface Programming Manual”. (Note: this manual also includes some commands that are not implemented in this instrument.

- Page 28 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust.
