VX462B
Pulse Generator
Module

The  VX462B  is  a  20Mhz  pulse
generator  with  additional  40Mhz
square  wave  capability.

Its

operating  modes  are  Normal,
Triggered,  Gated,  Delayed  pulse
and  Double  Pulse  (second  pulse
occurs  “delay”  time  after  Trigger
Out).   Front  panel  BNC  connectors
are  provided  for  Pulse  Out,  Trigger
Out  and  Trigger  (&  Gate)  In.   LED
indicators  are  provided  for  MODID
and  RUN.   The  unit  is  jumpter
selectable for low output impedance
capable

10V into a 50

Ω load or

Ω output impedance that provides

better matching for 50

Ω loads at

drive levels up to

5V.
