2.5 ns, and a rise time of 250 ps or less. The AVMP-1A-B-P-FOICC 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. -
Page 7: Front Panel Controls
FRONT PANEL CONTROLS 1. POWER Switch . The POWER push button switch applies AC prime power to the primaries of the transformer, turning the instrument on. The push button lamp (#382 type) is connected to the internal +15V DC supply. 2. - Page 8 If one of the adjustable numeric parameters is displayed, this 10 decreases the setting by a factor of ten. If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. EXTRA FINE This changes the step size of the ADJUST knob.

Page 9: Rear Panel Controls
REAR PANEL CONTROLS 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 8. GND Connector . This solder terminal is connector to the chassis ground.

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, three output channels respond to the trigger: OUT 1. This is the Channel 1 output. The maximum output voltage is +5V. ... - Page 12 Figure B The next figure illustrates the relationship between the signal when an external TTL- level trigger is used: Figure C...

Page 13: Trigger 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-1A-B-P-FOICC, instead of generating a low-amplitude pulse directly. -
Page 14: Obtaining Optimum Jitter Performance
OBTAINING OPTIMUM JITTER PERFORMANCE When jitter performance is a priority, it may be necessary to adjust the delay setting within a 5ns range to obtain the lowest jitter, as the jitter has a slight periodic delay dependency. TOP COVER REMOVAL The interior of the instrument may be accessed by removing the four Phillips screws on the top panel. -
Page 15: 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 LOAD The output stage may be damaged if the output is not terminated into a 50 load. NEVER APPLY AN EXTERNAL VOLTAGE TO THE OUTPUT Externally generated potentials must never be applied to the output, with the exception of the OS1 and OS2 offsets (see page 9). -

(attenuators, cables, connectors, etc.) should exceed 10 GHz. d) Set the oscilloscope to trigger externally with the vertical setting at 50 mV/div and the horizontal setting at 10 ns/div. 2. Turn on the AVMP-1A-B-P-FOICC. The main menu will appear on the LCD. - Page 17 3. To set the AVMP-1A-B-P-FOICC to trigger from the internal clock at a PRF of 2 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is.
- Page 18 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 20: 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. -
