.

+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 the basic instrument formats). Not
recommended for new designs. Use -B versions instead.
2)
-B suffix indicates IEEE-488.2 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 10% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external attenuators on the
output.
4)
The amplitude of the AVR-3-PW-TEK2-C may also be controlled by a 0 to +10V DC voltage applied to a rear-panel BNC connector, in addition to the standard front-panel
controls.
5)
Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative).
6)
An optional additional output module is available for "Output 2" of the AVR-3-PW-TEK3-B, which is suitable for use with CT-1 and CT-2 current probes. This output module
uses a very short length of de-solderable bus-bar wire (instead of flexible cable) which must be fed through the probe. Add the suffix "-CT" to the model number to specify
this option.
7)
Add the suffix -VXI to the model number to specify the Ethernet port.
