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, 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 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 is normally a delay of 5-10 seconds before anything is shown on the main display. If the main menu does not appear after 30 seconds, turn off the instrument and leave it off for at least 60 seconds before applying power again. - Page 16 5. LIQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with the keypad to change the instrument settings. Normally, the main menu is displayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenus in detail.

3. DC FUSES . These two fuses protect the internal DC power supplies. Please see the “FUSES” sections of this manual for more information. 4. TRIG . When the AV-151D-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 18 a password (“default”, as shipped from the factory) when logging into a serial terminal session. See the “Programming Manual for -B Instruments” for more details on RS-232 control. 7. Network Connector . (Optional feature. Present on -VXI units only.) This Ethernet connector allows the instrument to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols.

Page 20: Pulse Generation
SYNC output is not adjustable. PULSE GENERATION The AV-151D-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 (0.2 us to 500 ms), and the amplitude may be varied from 0 to +30V. -
Page 21: Amplify Mode
MAIN OUTPUT AMPLIFY MODE When the AMPLIFY mode is enabled, AV-151D-B may be used as a DC - 1 MHz variable-gain linear amplifier. The maximum gain is +15. The maximum input signal is ±2V. The gain is adjusted by varying the amplitude setting, which corresponds to the output that would be obtained for a +2V input. -
Page 22: Short Circuits
may be possible to reduce the distortions by adding a series resistance between the front-panel output connector and the cable. The RC time constant of this resistance and the cable capacitance will act as a passive filter which may remove some distortion, at the expense of slower rise and fall times. -

To set the AV-151D-B to trigger from the internal clock at a PRF of 1 kHz:... - Page 24 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 1 kHz. c) Press CHANGE to return to the main menu.

Page 28: 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 29: 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. -
