6.3.1 Extended Frequency Range
In selected Test Universe modules (e.g., Harmonics and PQ Signal
Generator ) the CMC 356 supports a mode for generating stationary signals
up to 3 kHz on the voltage outputs and the low-level outputs. This mode
corrects the phase and gain errors of the output filter. The 3 dB bandwidth of
this filter limits the amplitude at 3 kHz to about 70 % of the maximum range
value. The application of the extended frequency range is the generation of
harmonics and interharmonics.
