Page 4: Introduction
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 6: Installation
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 and two instrumentation manuals (this manual and the “OP1B Interface Programming Manual”) are with the instrument. -

FRONT PANEL CONTROLS 1. POWER Switch . This is the main power switch. 2. OVERLOAD . The AVMP-3-B-P-OT-ELA-R5 is protected in its internal software against conflicting or dangerous settings. As an additional protective measure, an automatic overload circuit exists, which controls the front panel overload light. If the... - Page 8 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. If one of the adjustable numeric parameters is displayed, this 10 increases the setting by a factor of ten.

REAR PANEL CONTROLS GATE TRIG RS-232 GPIB 1. AC POWER INPUT . A three-pronged recessed male connector is provided on the back panel for AC power connection to the instrument. Also contained in this assembly is a slow blow fuse and a removable card that can be removed and repositioned to switch between 120V AC in and 240V AC in. - Page 10 7. OS Connector . A DC offset may applied to this connector. Internally, it is connected to the output centre conductor via a high quality RF inductor. Do not exceed 50V, 250 mA. For this connector to be active, the OS ON/OFF switch (item 9) must be in the “OFF”...

Page 11: General Information
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. ... -

The next figure illustrates the relationship between the signal when an external TTL- level trigger is used: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 200 ns, FIXED SYNC OUT (generated by the 2 V, FIXED internal oscillator) DELAY... -
Page 13: Gating Modes
The pulse width and delay of the output pulse may vary slightly with the amplitude setting, particularly at lower amplitudes. For some demanding applications, it may be desirable to use external attenuators in conjunction with the AVMP-3-B-P-OT-ELA-R5, instead of generating a low-amplitude pulse directly. -
Page 14: Protecting Your Instrument
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 OMH LOAD The output stage may be damaged if the output is not terminated into a 50 load. -

Page 18: Programming Your Pulse Generator
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. -
