INTRODUCTION

The AVR-E5-B is a high performance, GPIB and RS2 2-equipped instrument capable

of generating up to 50V into 50Ω loads. The rise time (20%-80%) is less than 500 ps,

and the fall time (80%-20%) is less than 1 ns. The output pulse width is variable from

<1 ns to 10 ns, at repetition rates up to 1 MHz.

Instruments with the "-P" model suffix can generate up to +50V, whereas instruments

with the "-N" model suffix can generate up to -50V. Instruments with the "-PN" suffix

can generate both polarities.

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-E5-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.

The AVR-E5-B 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” of all key

instrument settings, and recall this setup at a later time.

This instrument is intended for use in research, development, test and calibration

laboratories by qualified personnel.

AVAILABLE OPTIONS

The AVR-E5-B is available with several options, including:

-OS Option: an externally generated DC offset can be added to the output.

-R5 Option: This is the optional rack-mounting kit. The R5 rack-mount kit may also be

ordered separately.

-VXI Option: Adds a rear-panel Ethernet connector, allowing the instrument to be

remotely controlled using the VXI-11. , ssh (secure shell), telnet, and http (web)

protocols. In particular, the VXI-11. features allows software like LabView to control an

instrument using standard VISA communications drivers and network cabling, instead

of using old-style GPIB cabling. (This eliminates the need for a GPIB controller card

and its proprietary drivers.)

SPECIFICATIONS

Model: AVR-E5-B2

Amplitude : (50 Ohm load8) Up to 50V

Rise time (20%-80%): 0.5 ns

Fall time (80%-20%): 1.0 ns

Pulse width (FWHM): 1 to 10 ns

Maximum PRF: 1 MHz

Polarity: Positive or negative or both (specify4)

DC offset or bias insertion: Option available5. Apply required DC offset or bias in the range of ± 25 Volts,

(250 mA max) to back panel solder terminals.

Trigger modes: Internal trigger, external trigger (TTL level pulse, > 10 ns, 1 kΩ input impedance),

front-panel “Single Pulse” pushbutton, or single pulse trigger via computer command.

Variable delay: 0 to 1.0 seconds, for all trigger modes (including external trigger).

Propagation delay: ≤ 160 ns (Ext trig in to pulse out)

Jitter: (Ext trig in to pulse out) ± 5ps ± 0.015% of sync delay

Sync output: Standard: + Volts, 100 ns, will drive 50 Ohm loads

Gate input: Synchronous or asynchronous, active high or low, switchable. Suppresses triggering when

active.

Connectors: Out: SMA, Other: BNC

Power requirements: 100 - 240 Volts, 50 - 60 Hz

GPIB and RS-2 2 control2: Standard on -B units.

LabView drivers: Check http://www.avtechpulse.com/labview for availability and downloads

Ethernet port, for remote control

using VXI-11. , ssh, telnet, &

web:

Optional6. Recommended as a modern alternative to GPIB / RS-2 2.

See http://www.avtechpulse.com/options/vxi for details.

Settings resolution: The resolution of the timing parameters varies, but is always better than 0.15% of the set value.

The amplitude resolution is typically 0.02% of the maximum amplitude.

Settings accuracya: Typically ± % (±2 ns or ± 2% of max. amplitude) after 10 minute warmup. For high-accuracy

applications requiring traceable calibration, verify the output with a calibrated oscilloscope.

Dimensions (H x W x D): 100 mm x 4 0 mm x 75 mm ( .9” x 17” x 14.8”)

Chassis material: cast aluminum frame and handles, blue vinyl on aluminum cover plates

Temperature range: +5°C to +40°C

1) -C suffix indicates stand-alone lab instrument with internal clock and line powering. (See http://www.avtechpulse.com/formats for additional details of

the four basic instrument formats).

2) -B suffix indicates IEEE-488.2 GPIB and RS-2 2 control of amplitude, pulse width, PRF and delay (see http://www.avtechpulse.com/gpib).

) For operation at amplitudes of less than 10% of full-scale, best results will

be obtained by setting the amplitude near full-scale and using external attenuators on the output.

4) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option. Polarity reversal achieved

by means of a two-position switch that controls the polarity of the signal output port on -C units, and via keypad control on -B units. -PN option not

available on -W units.

5) For DC offset option suffix model number with -OS.

6) Add the suffix -VXI to the model number to specify the Ethernet port..

7) Fall time increases to < ns for pulse widths less than 15 ns.

8) A 50Ω load is required. Other loads may damage the instrument. Consult Avtech (info@avtechpulse.com) if you need to drive other

load impedances.

REGULATORY NOTES

FCC PART 18

This device complies with part 18 of the FCC rules for non-consumer industrial,

scientific and medical (ISM) equipment.

This instrument is enclosed in a rugged metal chassis and uses a filtered power entry

module (where applicable). The main output signal is provided on a shielded connector

that is intended to be used with shielded coaxial cabling and a shielded load. Under

these conditions, the interference potential of this instrument is low.

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.

If any of the connectors on the instrument are unused, they should be covered with

shielded metal “dust caps” to reduce the interference potential.

This instrument does not normally require regular maintenance to minimize interference

potential. However, if loose hardware or connectors are noted, they should be

tightened. Contact Avtech (info@avtechpulse.com) if you require assistance.
