Page 5: Introduction
INTRODUCTION The Model AV-143B-PS DC-coupled linear amplifier has a gain (V ) of +5 V/V. The input may range from -4V to +4V. The input impedance is 1 kΩ. The corresponding output voltages are 0 to ±20V, into load impedances of 50Ω or greater. -
Page 6: Regulatory Notes
If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech (info@avtechpulse.com) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure. -

AC POWER SUPPLY REGULATORY NOTES This instrument converts the AC input power to the +24V DC voltage that powers the internal circuitry of this instrument using a Tamura AAD130SD-60-A switching power supply. According to the manufacturer, the Tamura AAD130SD-60-A has the following certifications: UL60950-1 IEC60950 -1... -
Page 9: Installation
INSTALLATION VISUAL CHECK After unpacking the instrument, 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. If the instrument has been damaged, file a claim immediately with the company that transported the instrument. -

ENVIRONMENTAL CONDITIONS This instrument is intended for use under the following conditions: 1. indoor use; 2. altitude up to 2 000 m; 3. temperature 5 °C to 40 °C; 4. maximum relative humidity 80 % for temperatures up to 31 °C decreasing linearly to 50 % relative humidity at 40 °C;... -
Page 12: 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 13: 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... -

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 15 4. OUT Connector . This BNC connector provides the main output signal. The output is an amplified version of the input on (3).

Page 16: 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. -
Page 17: General Information
GENERAL INFORMATION BASIC CONTROL The AV-143B-PS is a DC-10 MHz fixed-gain linear amplifier. The gain is fixed at +5 V/V. The required voltage input signal is applied at the “IN” connector. This mode is illustrated below: ARBITRARY WAVEFORM, INPUT VOLTAGE, ON , ±4 V MAXIMUM... -
Page 18: Operational Check
2) Set the signal generator to produce a +4V, 10 kHz waveform. (The input impedance of the AV-143B-PS is 1 kΩ). Connect a cable from the SYNC connector of the signal generator to the TRIG input of an oscilloscope. Set the oscilloscope to trigger externally. - Page 19 5) Turn on the amplifier and the signal generator. 6) The Channel B waveform should increase to +20V, and have a shape similar to that of the Channel A waveform. 7) This completes the operational check.

Page 20: 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 21: 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. -
