20 kHz. The pulse width is adjustable from 4 to 50 ns. The rise times are 2.5 ns or less, and the fall times are 3.5 ns or less. The AVO-9W-B-P-P0E consists of a mainframe unit and an AVX-S3C series output module, which provides a socket into which the user's laser diode may be inserted. The mainframe generates voltage pulses of up to +125V. - Page 6 The AVO-9W-B-P-P0E features front panel keyboard and adjust knob control of the output pulse parameters along with a four line by 40-character backlit LCD display of the output amplitude, pulse width, pulse repetition frequency, and delay. The instrument includes memory to store up to four complete instrument setups. The operator may use the front panel or the computer interface to store a complete “snapshot”...

laws) on behalf of the customer, as provided for under Article 9 of Directive 2002/96/EC. Customers who have purchased Avtech equipment through local representatives should consult with the representative to determine who has responsibility for WEEE compliance. Normally, such responsibilities with lie with the representative, unless other arrangements (under Article 9) have been made. -
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, two instrumentation manuals (this manual and the “Programming Manual for -B Instruments”), and the output module are with the instrument. -

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. 2. - 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.

Page 23: Amplitude Control
The 6Ω resistance is built into the AVX-S3C output module. The AVO-9W-B-P-P0E can deliver up to 125V to the output module, which is halved by the current-doubling transformer to 62V, approximately. The maximum available output current is thus 62V / 6Ω... -

If the delay is negative, the order of the SYNC and OUT pulses is reversed: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT The next figure illustrates the relationship between the signal when an external TTL- level trigger is used: >... -
Page 25: Gating Modes
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. Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by using the appropriate programming commands. -

MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. -
Page 34: 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. -
