NOTE . It is possible to set a combination of WFMPre:XUNit and
WFMPre:YUNit for a reference waveform that is inconsistent (for
example, seconds with dB or Hertz with volts). The oscilloscope will
not warn you of this condition. The oscilloscope uses WFMPre:XU-
Nit to determine whether the waveform is a YT or an FFT.
For TDS200 oscilloscopes used with a TDS2CMA communications
or a TDS2MM measurement module, the set form is ignored. Refer to
the WFMPre:YMUlt command for equivalent functionality.
The query form returns the vertical units of the waveform specified
by the DATa:SOUrce command, if that waveform is active or
displayed. If that waveform is not active or displayed, the query fails
and the oscilloscope generates an execution error with event code
2244 (waveform requested is not active).
Waveform
WFMPre:YUNit <qstring>
WFMPre:YUNit?
<qstring> is Volts", U", or dB"
Volts" for volts, U for unknown units (divisions), or dB" for
decibels.
