INTRODUCTION
The AVI-V-B-N-VCB is a high performance, GPIB and RS232-equipped instrument
capable of generating -5V to -50V into 50Ω loads. The rise times are less than 350 ps,
and the fall times are less than 1 ns. The output pulse width is variable from 3 to 12 ns,
at repetition rates up to 20 kHz.
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 AVI-V-B-N-VCB 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 AVI-V-B-N-VCB features front panel keyboard and adjust knob control of the output
pulse parameters along with a four line by 0-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.

1) -C suffix indicates stand-alone lab instrument with internal clock and line powering. No suffix indicates miniature module requiring DC power and external trigger. (See
http://www.avtechpulse.com/formats for details of the basic instrument formats).
2) -B suffix indicates IEEE- 88.2 GPIB and RS-232 control of amplitude, pulse width, PRF and delay. (See http://www.avtechpulse.com/gpib).
3) For operation at amplitudes of less than 20% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external attenuators on the output.

http://www.avtechpulse.com/speed/avi-v
Quantity: 1-3
Price: $XXXXX US each DDU (Delivered Duty Unpaid). Includes the cost of
shipping and insurance, but excludes customs duties, taxes, and other
import fees. Shipments are from Canada, and are normally duty-free.
Delivery: 8 weeks after receipt of order (excluding export permit* delays).
Quote valid for: 8 weeks
Because of the low volume and custom nature of our business, we do not
provide demos. For a view of typical test results for standard AVI units
see http://www.avtechpulse.com/ and click on the "Test Results" line.
Also, you may wish to consider ordering a single unit first.
*Export Permit: These instruments are very high performance pulse
generators, which are considered to be "Nuclear-Related Dual-Use Goods"
under government regulations. As such, an "End Use Statement - High
7

Speed Models" form must be completed when ordering. The necessary form
is attached (in PDF format), and is also available at
http://www.avtechpulse.com/end-use/EndUseStatement,HighSpeed,v6.pdf. We
will use the information in the completed form to apply for an export
license from the Canadian government, which will take 1 to 6 weeks to
obtain. We cannot ship your order without the license. Please return the
completed form to us by fax.
Please call or email me if I can be of further assistance.
Thank you for your interest in our products!

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. 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 (i[email protected]m) 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 ([e-mail]) if you require assistance.
