Page 5: Introduction
The AV-153A-B will drive load impedances of 5 k or higher. The AV-153A-B can also drive capacitive loads, at reduced frequencies. When supplied with an external voltage input, the AV-153A-B may be used as a DC to 300 kHz variable-gain linear amplifier. The gain is variable from +1 to +100. -

SPECIFICATIONS Model: AV-153A-B Output amplitude 0 to 200 Volts GPIB and RS-232 control: included Load resistance: 5 k Avg. output power: 15 Watts maximum Minimum frequency: 30 Hz Maximum frequency: 300 kHz (5 k0 nF) (for a given load resistance 60 kHz (5 k1 nF) -
Page 8: 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, a GPIB cable, and two instrumentation manuals (this manual and the “Programming Manual for -B Instruments”) are with the instrument. - Page 9 If it is not set for the proper voltage, remove the fuse and then grasp the card with a pair of pliers and remove it. Rotate horizontally through 180 degrees. Reinstall the card and the correct fuse. In the 120V setting, a 1.0A slow blow fuse is required. In the 240V setting, a 0.5A slow blow fuse is required.

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 11 which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenus in detail. 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.

3. GATE . This connector is not used in the AV-153A-B. 4. TRIG . When the AV-153A-B is set to operate in the amplifier mode, the externally- generated input signal is applied to this connector. The maximum input voltage is ±2V. - Page 13 The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thru 50 Ohm terminator is suggested for this purpose.) 5. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “OP1B Interface Programming Manual”...

Page 15: Pulse Generation
PULSE GENERATION The AV-153A-B can also act as a pulse generator, with variable delay between the SYNC output and the main output. In this mode, the pulse width may be varied over a wide range (1 us to 500 ms), and the amplitude may be varied from 0 to +200V. -
Page 16: Resistive And Capacitive Loads
± 200V MAXIMUM RESISTIVE AND CAPACITIVE LOADS The AV-153A-B can drive resistive loads with impedances of 5000 Ohms and higher. At reduced frequencies, the AV-153A-B can also drive a capacitive load of up to 10000 pF. The reduced maximum frequencies and increased rise times are outlined in the... -
Page 17: Mechanical Information
Always disconnect the power cord before opening the instrument. 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. Caution: High voltages are present inside the instrument during normal operation. -
Page 18: 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. -

100 V/div, and the horizontal scale to 20 us/div. 4. Turn on the AV-153A-B. The main menu will appear on the LCD. 5. To set the AV-153A-B to trigger from the internal clock at a PRF of 30 kHz:... - Page 20 a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. b) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 30 kHz. c) Press CHANGE to return to the main menu.
