Features
Digital Enable
A BNC connection for a TTL compatible signal
to turn ON/OFF the high voltage output is
provided. TTL high (or open) turns off the HV
output; TTL low turns on the HV output.
Response
A graduated 1-turn panel potentiometer is used
to optimize the AC response for various load
parameters.
High Voltage LED
Front panel red LED illuminates when the high
voltage is on.

Note
The output cable supplied with this instrument uses a coaxial cable that
has 30.8 pF/ft of capacitance at 1 kHz nominal. This cable capacitance
must be factored in as a portion of the load and will reduce slew rates
and large signal bandwidth. In applications that require maximum
performance it is suggested that the supplied high voltage coaxial cable
be kept as short as possible to reduce capacitance. Another option is
to cut the coaxial cable short and add two break out leads (1 for shield
[ground] and 1 for the center conductor) for the connection to load.
