Introduction
The PASCO CI-6552A Power Amplifier II is an acces-
sory to the PASCO Signal Interfaces, Series 6500 and
Mac65. It amplifies the output of the computer, allowing
it to be used as a controlled DC power source or an AC
function generator.
With the Power Amplifier II plugged into one of the ana-
log channels of the Signal Interface, the appropriate soft-
ware (Power Amplifier for DOS, Power Amplifier for
APPLE II, or Science Workshop) can be used to generate
the following types of waves (up to ±10V peak at 1A, up
to 5,000 Hz):
• sine,
• square,
• triangle, and
• sawtooth.
This means the computer can now be used as an AC sig-
nal generator to power external circuits while it monitors
its own output current as well as other inputs. The Science
Workshop software can also generate a DC output.
Filter Select Switch
The CI-6552A Power Amplifier II has a filter select
switch which is preset for use with the CI-6560 Signal
Interface II (Mac65). The bandwidth at that switch posi-
tion is about 100KHz, limited by the power amplifier’s
feedback compensation section and the load. When using
the Power Amplifier II with the CI-6510 Signal Interface
(Series 6500), the bandwidth needs to be limited to
1.5KHz. To change the switch position push the filter se-
lect switch in the back panel slot to the left, as shown in
the illustration below.
