Measuring Multiplexed Analog Input Signals
The following section demonstrates how testing the evaluation board performance with full-scale, multi-
plexed input signals is performed once the hardware and software are configured.
Connect a 1 kHz, -0.5 dB signal to one analog input channel, and a 5 kHz, -0.5 dB signal to the other an-
alog input channel.
Select the Frequency Domain window by clicking on the Frequency Domain tab at the top of the screen.
Deactivate the Grounded Input FFT button. Activate the Log Freq Scale button. Select the Window Type
to be Crystal 7 Term.
