The AVI series provides high amplitude (as high as 100 volts) flat topped pulse outputs with rise times as low as 200 psec and fall times of 2 nsec. Units with maximum pulse repetition frequencies of 20 KHz and 5 KHz feature output pulse widths variable over the range of 0 to 100 nsec by means of a one turn control. Models AVI-V-C and AVI-HV1 -C provide output amplitudes variable from 0 to 50 volts with rise times of 350 psec and 250 psec respectively. Models AVI-HV2-C and AVI-HV3- C provide peak amplitudes of 100 volts and rise times of 500 psec and 200 psec.

The pulse repetition frequency is variable from 50 Hz to 20 KHz (to 5 KHz for -HV2-C and -HV3-C units) using the internal clock oscillator which is controlled by a front panel one turn control. A delay control and sync output is provided for sampling scope triggering purposes. The units can also be triggered externally using a TTL level pulse. The propagation delay in the externally triggered mode is typically 250 nsec. Either output polarity or an optional dual output polarity can be provided. Polarity inversion in dual polarity units is accomplished by means of a built-in inverting transformer and a coaxial jumper cable which connects the transformer to the uninverted output port. A DC offset or bias insertion option is available. Units with this option include a circuit similar to Model AVX-T at the output. The required DC offset or bias is applied directly to rear panel solder terminals. Some AVI units are also available with a monitor output option which provides an attenuated (20 db or X10) coincident replica of the main output pulse. Models with the -C suffix require 120/240V (switchable) 50-60 Hz prime power.

All AVI units are also available in a line powered chassis without the internal clock (-PS suffix) and in DC powered (+15V) miniature module form. The modules and -PS units require a low level slow speed input TTL trigger signal and the output PRF equals the input trigger PRF. Module units AVI and AVI-MP offer PRF up to 1.0 MHz with pulse width control via an external delay line.

The AVI series is ideally suited for systems or laboratory applications such as logic family propagation testing, TDR, radar, optical and cable communications, SAW, nuclear, switching and propagation time studies and educational fields. In some cases, the specifications can be adapted to satisfy a particular requirement. Contact the factory for your special requirement.
