By default, the units are decibels with a ceiling of 10dB and a floor of -90dB. The first side panel control block is the Magnitude plot configuration window. When using a device with more than two channels, these channels are also present in the plot panes and have their own configuration options. To view the channel 1 phase plot decreasing from 0 degrees to -90 degrees (this is the phase of the filter's frequency response), set the phase reference to channel 2. With the Wavegen connected to the scope channel 2 input, the plot panes should show channel 2 (blue trace) as a flat 0db magnitude plot, channel 1 (yellow traces) magnitude plot decreasing from 0dB to -40dB (this is the magnitude of the filter's frequency response). Click Single ( ) to sweep the circuit network only once. Click Stop to stop outputting analog voltages, and to stop capturing data on the analog input pins. While sweeping, the Run button ( ) changes to Stop ( ). From the control bar, click Run to continuously sweep the circuit network with an input signal of varying frequency - by default, the frequency sweep ranges from 1 kHz to 1 MHz.
