Audio filter test & measurement with Picoscope & 2204A – PART 2

Noise Generator output, as seen on the 2204A scope, is shown in Figure 1. Same output, as seen on the 2204A Spectrum Analyser is shown in Figure 2, showing Wideband Noise to 97 KHz. This and all other PC screen photos to be posted were obtained with the following settings of the FFT options:
-Window Functions: Gauss.
- Y axis: Average.
- Log unit: dBm/600 Ohm

The Average function of course slows down the measurement process, but provides a very neat display. Also uploaded is the calculated response of the filters to be tested.
