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