Level Meters

The Level meters show the RMS level as a coloured bar and a numeric value at the bottom of the meter and the peak value as a red line and a numeric value at the top of the meter. Levels shown on the bar are in dB below Full Scale. The numeric value for the output meters is in the units that have been selected on the generator (dBu, dBV, Volts or dBFS). The numeric value for the input meters is in the units selected by right-clicking on the meter (dB SPL, dBFS, dBu, dBV, dBW, Volts or Watts), values other than dBFS depend on the input full scale setting on the RTA window or, for SPL, the SPL meter calibration.

If the signal generator is playing a sine wave the lower panel shows the gain and phase of the measurement input relative to the reference input at the signal generator frequency, this may be useful for checking inter-channel gain and phase if both channels are fed the same signal.
