HIStogram:SOUrce
Description
This command sets or queries which source will be compared against
the histogram box when the histogram testing is enabled. This is equiv-
alent to selecting Waveform Histograms from the Measure menu and
then choosing the desired waveform source. The waveform need not be
displayed for histograms to run. You might want the channel displays
disabled so you can see a full --screen histogram and not have waveform
data confuse the display.
