Page 5: Introduction
INTRODUCTION The AVO-5C-C is a high performance instrument capable of generating up to 8 Amps into low impedance loads at repetition rates up to 5 MHz. The output pulse width is variable from 5 to 50 ns, and the sync delay is variable up to 200 ns. The rise and fall times are less than 3 ns typically. - Page 6 -M Option: a monitor output is provided.

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 connector is an output, which supplies a 2V, 50 ns wide pulse for each trigger 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).

REAR PANEL CONTROLS SMOOTH 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 AVO-5C-C should be tested with a sampling oscilloscope with a bandwidth of at least 1 GHz to properly observe the high-speed waveform. A typical test arrangement is shown below: A Tektronix CT-2 or Integrated Sensor... -
Page 19: Waveform Distortions
where V is the voltage drop across the diode, R is the parasitic resistance of DIODE DIODE the diode, and R is the resistance of the series resistor. R should be SERIES SERIES DIODE equal to 6.2 Ohms for the AVO-5C-TA, and 1.5 Ohms for the AVO-5C-TB. Aside from providing the required termination, the added series resistance may also be used to monitor the output current waveform. -
Page 20: Basic Pulse Control
BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. When triggered internally, two mainframe output channels respond to the trigger: OUT and SYNC. • OUT. This is the main output. •... -
Page 21: Parameter Interaction
PARAMETER INTERACTION The pulse width, amplitude, and frequency controls may all interact to some extent. If you change the PRF by switching ranges, the output pulse may “disappear” because the pulse width has shifted. Simply adjust the pulse width control until the pulse re-appears. -
Page 22: Minimizing Waveform Distortions
In particular, wire-wound resistors should be avoided. PREVENTING DAMAGE The AVO-5C-C may fail if triggered at a PRF greater than 5 MHz, or if the duty cycle exceeds 10%. The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. -
Page 23: Mechanical Information
MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. -
Page 24: 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. -
