Trek 668B High-Voltage Reference Supply - Manual

Model 668B
Precision, High-Voltage
Reference Supply
The Trek Model 668B is a precision, high-voltage, reference
power supply with an adjustable output voltage range of 0 to
3 kV DC or 0 to -3 kV DC and an output current capability of up to
±5 mA DC.
Front panel push-buttons are used to select the desired output
voltage with 100 mV resolution. Each decade of the output
voltage is independently controlled by its own set of up and
down push buttons.
Current control is provided by front panel selection of either
supply trip-off or limiting at the preset current value.
Nine programmable memory locations are provided for saving
and recalling frequently used output voltage and current
settings.
A voltage setting (including polarity) and a current limit or trip
value can be stored in each memory location.
The memory locations can be accessed from the front panel or
through an optional digital communications interface.
An easy-to-read, sixteen-character LED display indicates the
output voltage, the current limit or current value, as well as the
memory location currently selected.
The Digital Enable feature provides a connection for a TTL
signal or a switching device to turn on and off the high voltage
remotely. The optional digital communications interface is well
suited for automated test equipment applications.
The 668B can be operated on a bench top or, with optional
hardware, in a 19-inch rack.
