Page 6: Introduction
A 50 Ohm load is required for proper operation. The output stage may be damaged if the output is not terminated into a 50Ω load. The AVR-E3-B is a highly flexible instrument. Aside from the internal trigger source, it can also be triggered or gated by external TTL-level signals. A front-panel pushbutton or a computer command can also be used to trigger the instrument. -
Page 7: Available Options
AVAILABLE OPTIONS The AVR-E3-B is available with several options, including: -ATT Option: Adds internal relay-switched 10 dB and 20 dB attenuators to provide improved low-amplitude performance. The attenuators are automatically enabled based on the programmed amplitude, and can handle the full output power of the instrument. -
Page 8: Specifications
6) Add the suffix -VXI to the model number to specify the Ethernet port.. 7) Fall time increases to < 3 ns for pulse widths less than 15 ns. A 50Ω load is required. Other loads may damage the instrument. Consult Avtech (info@avtechpulse.com) if you need to drive other load impedances. -
Page 9: 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. -

Page 13: 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 16: 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 17: 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 for standard models: Recommended Replacement Part Nominal Fuses... -
Page 18: 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 19 for -B Instruments” describes the menus and submenus in detail. 6. KEYPAD. Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten.

An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. - Page 21 6. GPIB Connector. A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on GPIB control. 7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be attached to this connector to allow the instrument to be computer-controlled.

Page 24: Gating Modes
GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector. The instrument can be set to stop triggering when this input high or low, using the front- panel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. -
Page 25: Optional Features
OPTIONAL FEATURES RACK MOUNTING, -R5 OPTION A rack mounting kit is available. The -R5 rack mount kit may be installed after first removing the one Phillips screw on the side panel adjacent to the front handle. DC OFFSET, -OS OPTION A DC offset can be added to the output signal by applying a DC voltage to the rear-panel OS connector. -
Page 26: Protecting Your Instrument
PROTECTING YOUR INSTRUMENT TURN OFF INSTRUMENT WHEN NOT IN USE The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use. In the case of failure, the switching elements are easily replaced following the procedure described in a following section. -
Page 27: Operational Check
A 50 Ohm load is required for proper operation. The output stage may be damaged if the output is not terminated into a 50Ω load. The AVR-E3-B output may be observed using either a high-speed sampling oscilloscope, or a slower real-time oscilloscope. To accurately observe these rising and falling edges, a sampling oscilloscope with a bandwidth of 2 GHz is required. - Page 28 200 V/div for real-time scopes, and the horizontal setting at 20 ns/div. 2.

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 35: 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. -
