Trek Model PZD700A
Piezo Driver/Power Amplifier
The Trek Model PZD700A is a high-voltage DC-stable piezo
driver/amplifier designed to provide precise control of output
voltages in bipolar or unipolar ranges which are customer
specified within a range of available settings. The instrument
achieves the accurate output responses and high slew rates
demanded by reactive loads by utilizing a four-quadrant active
output stage that sinks or sources current into reactive or
resistive loads.
The Model PZD700A is configured as a non-inverting amplifier.
An inverting configuration is available. Both configurations are
available as either single or dual channel instruments. They are
bench top operable or 19-in rack mountable.
