Trek 603 User Manual
Trek Model 603
Piezo Driver/Power Amplifier
The Trek Model 603 is a high-voltage DC power amplifier/piezo
driver designed to provide precise control of output voltages in
bipolar or unipolar ranges that 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 603 is configured as a non-inverting amplifier. An
inver tin g con figur atio n is o ptio nally availab le. Both
configurations are available in single or dual channel packaging.
They are operable on a bench top or in a 19-in rack.
