Trek 2205 User Manual
Trek Model 2205
Piezo Driver/Power Amplifier
The Trek Model 2205 is a member of Trek’s 2200-series of
high-voltage 40 W amplifiers that offers high performance at
an attractive price. It incorporates DC stability, wide
bandwidth, well regulated and controlled AC output signals,
full four-quadrant class AB all-solid-state output stages, DC
offset adjustment with front panel metering, and autorecovery shutdown to protect the output from being
overpowered. The instrument also stage sinks or sources
current into reactive or resistive loads throughout the output
voltage range which makes it ideal to achieve the accurate
output response and high slew rates demanded by reactive
loads.

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 (one for shield [ground] and one for the center conductor) for the
connection to load.
