:WAVeform:SEGMented:ALL
Command Syntax
:WAVeform:SEGMented:ALL {{0 | OFF} | {1 | ON}}
The :WAVeform:SEGMented:ALL command enables or disables the "waveform
data for all segments" setting:
• ON — The :WAVeform:DATA? query returns data for all segments.
ON is available only when the :WAVeform:SOURce is an analog input channel.
When ON, the :WAVeform:DATA? query returns data for the number of
segments multiplied by the number of points in a segment (which is the points
value returned by the :WAVeform:POINts? or :WAVeform:PREamble? queries).
• OFF — The :WAVeform:DATA? query returns data for the current segment.
The ability to get waveform data for all segments is faster and more convenient
than iterating over multiple segments and retrieving each one separately.
The performance improvement comes primarily when raw acquisition record data
is being retrieved (:WAVeform:POINts:MODE RAW) instead of the measurement
record data (:WAVeform:POINts:MODE NORMal).
One corner case where you may want to retreive the measurement record data is
when the acquired data for a segment is less than the screen resolution and the
measurement record is interpolated.
Most often though, the acquired data for a segment is enough to fill the screen,
and less than the maximum measurement record size, so the segmented raw
acquisition data and the measurement record data are the same.
If the number of segments is small, the raw acquisition segment size is greater
than the measurement record size.
Query Syntax
:WAVeform:SEGMented:ALL?
The :WAVeform:SEGMented:ALL? query returns the "waveform data for all
segments" setting.
