Units for each input channel can be set to Volts or Amps using the Units softkey in the
channel's Probe Menu. Scale and offset units are:

* When the FFT source is channel 1, 2, 3 or 4, FFT units will be displayed in dBV when channel
units is set to Volts and channel impedance is set to 1 M
when channel units is set to Volts and channel impedance is set to 50
displayed as dB for all other FFT sources or when a source channel's units has been set to Amps.
A scale unit of U (undefined) will be displayed for math functions when two source
channels are used and they are set to dissimilar units and the combination of units
cannot be resolved.
