Page 5: Introduction
INTRODUCTION The AVR-AHF-1-B is a high performance, GPIB and RS232-equipped instrument capable of generating up to 250V at repetition rates up to 100 kHz into loads of 50Ω or higher. The pulse width is variable from 50 to 500 ns, and the duty cycle may be as high as 4%. -
Page 6: Available Options
AVAILABLE OPTIONS -EA Option: The amplitude can be controlled by an externally generated 0 to +10V analog control voltage. -R5 Option: Rack-mount kit. -VXI Option: Adds a rear-panel Ethernet connector, allowing the instrument to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. -

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. -

Requirements for WEEE compliance may include registration of products with local governments, reporting of recycling activities to local governments, and financing of recycling activities. -
Page 11: 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 14: 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 15: 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: Nominal Recommended Replacement Part Fuses... -
Page 16: 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 10 seconds before anything is shown on the main display, as the internal operating system boots up. 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 17 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.

REAR PANEL CONTROLS GATE TRIG RS-232 GPIB Note: some connectors may be in different positions than shown above, depending on the exact combination of options ordered. 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 19 When triggering externally, the instrument can be set such that the output pulse width tracks the pulse width on this input, or the output pulse width can be set independently. 6. GPIB Connector . A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled.

Page 20: General Information
GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the load. Its amplitude and pulse width are variable. - Page 21 > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure C As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed. The last figure illustrates the relationship between the signal when an external TTL-level trigger is used in the PW mode.
-
Page 22: Trigger Modes
TRIGGER MODES This instrument has four trigger modes: Internal Trigger: the instrument controls the trigger frequency, and generates the clock internally. External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector. Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton. -
Page 23: Electronic Amplitude Control, "-Ea" Option
ELECTRONIC AMPLITUDE CONTROL, "-EA" OPTION The output amplitude can be set to track the voltage on this input. Zero Volts in corresponds to zero amplitude output, and +10V in corresponds to maximum amplitude out. This mode is activated by selecting "Ext Control" on the front-panel amplitude menu, or with the "source:voltage external"... -

Then read the “Local Control” section of the “Programming Manual for -B Instruments” thoroughly. The “Local Control” section describes the front panel controls used in this operational check - in particular, the MOVE, CHANGE, and ADJUST controls.

Page 30: 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 31: 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. -
