Page 5: Introduction
INTRODUCTION The AVMP-4-C is a high performance instrument capable of generating up to 10V into 50Ω loads at repetition rates up to 1 MHz. The rise time and fall times are less than 200 ps. The pulse width is variable from 10 ns to 10 us, and the maximum duty cycle is 10%.
Page 6: Available Options
AVAILABLE OPTIONS The AVMP-4-C is available with several options: -EA Option: the output amplitude can be controlled by an externally generated 0 to +10V analog control voltage. -ECL Option: the input trigger levels are ECL, rather than TTL. -EW Option: the output pulse width can be controlled by an externally generated 0 to +10V analog control voltage.
Page 7: Specifications
7) Polarity inversion in dual-polarity AVMP-2-C and AVMP-3-C units is achieved by manually adding a supplied inverting transformer accessory to the main output. The transformer will increase the rise and fall times slightly. Polarity inversion in dual-polarity “-B” units, and the AVMP-4-C, is controlled by front-panel settings (or computer command for -B units), and no external transformer is required, and no speed degradation occurs when changing polarities.

Directive 2002/96/EC categories 1-7 and 10, as stated in the "Article 2 - Scope" section of Directive 2002/95/EC. DIRECTIVE 2002/96/EC (WEEE) European customers who have purchased this equipment directly from Avtech will have completed a “WEEE Responsibility Agreement” form, accepting responsibility for WEEE...
Page 9 Article 9 of Directive 2002/96/EC. Customers who have purchased Avtech equipment through local representatives should consult with the representative to determine who has responsibility for WEEE compliance. Normally, such responsibilities with lie with the representative, unless other arrangements (under Article 9) have been made.
Page 10: Installation
INSTALLATION VISUAL CHECK After unpacking the instrument mainframe and the transformer module, examine to ensure that they have not been damaged in shipment. Visually inspect all connectors, knobs, and handles. Confirm that a power cord and an instrumentation manual (this manual), are with the instrument.

Page 13: Fuses
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 14: Dc Fuse Replacement
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: Recommended Replacement Part Nominal Fuses...
Page 15: Front Panel Controls
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 16 event. This output may be used to trigger oscilloscopes or other equipment. 5) Delay Controls . When the PRF Range Switch is set to one of the four internal oscillator ranges, the main output is advanced or delayed relative to the TRIG output pulse (item 3).
Page 17: Rear Panel Controls
REAR PANEL CONTROLS 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 18: General Information
GENERAL INFORMATION BASIC TEST ARRANGEMENT The AVMP-4-C should be tested with a sampling oscilloscope with a bandwidth of at least 10 GHz to properly observe the high-speed waveform. (The cables and attenuators must also have a bandwidth of at least 10 GHz.) A typical test arrangement...

200 ns, FIXED TRIG (generated by the 2V, FIXED internal oscillator) DELAY PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT When the ADVANCE/DELAY switch is set to “DELAY”, the TRIG output occurs after the main output. This illustrated below: 200 ns, FIXED TRIG (generated by the 2V, FIXED...
Page 20: Minimizing Waveform Distortions
PREVENTING DAMAGE The AVMP-4-C may fail if triggered at a PRF greater than 1 MHz. This unit is designed to operate into a load impedance of 50 Ohms and the output stage will be damaged if it is operated into an open circuit (or any other high impedance).
Page 21: Mechanical Information
There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel.
Page 22: Maintenance
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.
