2) These parameters can easily be adapted to meet special requirements. Contact Avtech (info@avtechpulse.com) with your special application. 3) To specify the DC offset option, add the suffix -OS to the model number. The sum of the amplitude and the offset must remain within the rated output amplitude range –... -
Page 7: 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. -

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 compliance (as mandated in Directive 2002/96/EC of the European Union and local laws) on behalf of the customer, as provided for under Article 9 of Directive 2002/96/EC. -
Page 9: Ac Power Supply Regulatory Notes
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 10: Installation
INSTALLATION VISUAL CHECK After unpacking the instrument, examine to ensure that it has not been damaged in shipment. Visually inspect all connectors, knobs, and handles. Confirm that a power cord is 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 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... -

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 standard coaxial cable, to ensure that the center conductor is not exposed. 6. OFFSET Controls . (Optional: -OS option only.) This dial varies the DC offset on the output from 0 to ±200V. The ON/OFF switch below the dial enables and disables this function.

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
The AV-112A-PS can drive resistive loads with impedances of 5 kilohms and higher. At reduced frequencies, the AV-112A-PS can also drive a capacitive load of up to 6.8 nF. The reduced maximum frequencies and increased rise times are outlined in the... -
Page 19: Cable Lengths
CABLE LENGTHS The length of cable used to connect the load to the output of the function generator should be less than 3 feet (1 meter), and ideally less than 18 inches (0.5 meters). At longer lengths, the transmission line reflections caused by the cabling will distort the output signal, particularly if the signals with fast rise times are used. -
Page 20: Operational Check
2) Set the signal generator to produce a ±2V, 25 kHz waveform. (The input impedance of the AV-112A-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 21 5) Set the gain control to minimum (0.0). Turn on the amplifier and the signal generator. 6) Channel A should show a ±2V, 25 kHz waveform from the signal generator. Rotate the gain control to its maximum setting. The Channel B waveform should increase to ±200V, and have a shape similar to that of the Channel A waveform.

Page 22: 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 23: 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. -
