Remarks
– The unit for the scale specified must correspond to the existing unit in the
selected memory slot.
– If no waveform data exists in the selected memory slot, error –221,“Settings
conflict;No data in waveform memory slot” will occur.
– If you set a scale value which exceeds its minimum or maximum limit, the value
will be clipped to its minimum or maximum value respectively. Error
–222,“Data out of range;Value clipped to minimum (#)” or –222,“Data out of
range;Value clipped to maximum (#)” will occur.
Query
WMEMory{1|2|3|4}:SCALe?
This query returns the current setting of the waveform scale of the specified
memory slot. The response format is
<NRf>
in the following units:
– dB/div or W/div (for waveforms of channels 1 and 4)
– V/div (for waveforms of channels 2 and 3).
Query example
WMEM2:SCAL?
Queries the waveform scale setting of memory slot 2.
