Introduction

The PASCO CI-6552A Power Amplifier II is an accessory 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 analog channels of the Signal Interface, the appropriate software (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 signal 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 position 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 select switch in the back panel slot to the left, as shown in the illustration below.
