4.10.3: Using Calibration Mode
Application:
The PCAP II Plus calibration mode allows verification of the PCAP II Plus functionality.
When enabled the PCAP II Plus will output on both digital and analog outputs the signal type
selected in the Signal Generator Output area. One of a number of tests can be selected and run
via the Run Test button. To download a complete calibration and test procedure in “.pdf”
format, please visit the DAC website at www.dacaudio.com.

Upon enabling the Calibration Mode, the Software Input Level Controls will be enabled to allow
precise control of input levels. The AGC will be disabled to allow a constant output level. Note
that if you use an RCA cable to loop the output to the input of the PCAP II Plus, you will be able
to view the effects of filters through the signal path with the Spectrum Analyzer. However, you
will not be able to listen to the filter effects as the PCAP II Plus will always output the pure
generated signal while in Calibration Mode.
