Averaging Controls
Starts and stops the average of the averaging of the spectrum.
Once the Average Time in completed, the user is asked if the current spectrum
should be used as the reference.
Resets the averaging of the spectrum.
The elapsed time since the beginning of the averaging.
The duration of the averaging.
Current spectrum on inputs
Spectrum Graph The FFT spectrum of the enabled inputs.
The legend of the plots and the global levels of are displayed in the upper right
corner.
Sets the frequency axis in linear or logarithmic mapping.
Rescales the amplitude axis.
The frequency weighting selects the unit of the spectrum (dBA, dBC or dBZ).
Generator Setup
Sets the tone generator frequency.
Sets the tone generator output level, white noise generator and DC offset. The
level is a fraction of full output range, which is around 2.1 V.
Maps each signal (tone generator, white noise generator and DC offset) to the
specified output (output 1, output 2 or none).
If several parts of the generator are mapped to the same output, parts will sum
up to form the output signal. If the absolute sum of the levels that form a given
output exceeds 100%, saturation may occur at the output.
