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 50load or  
50output impedance that provides  
better matching for 50loads at  
drive levels up to +5V.
