Mounting:

Any

Temperature range:

+5°C to +40°C

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 four basic instrument formats). 

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 analog electronic control (0 to +10V) of the amplitude, suffix model number with -EA. Electronic control units also include standard front-panel 

controls.

4) 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.

5) For 10-turn dial control of pulse width (or amplitude) suffix model number with -PWT (or -AT). For -C units only.
6) Indicate desired polarity by suffixing model No. by -P or -N (i.e. positive or negative) or -PN for dual polarity option. Polarity reversal is achieved by 

means of a two-position switch on -C units and by keypad control on -B units.

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