DATA:ATTRibute:AVERage? [<arb name>]
Query the arithmetic average of all data points for the specified
arbitrary waveform. The default arb name is the arbitrary waveform
currently active (selected with FUNC:USER command).
If you query a waveform that is not currently stored in memory,
a +785, “Specified arb waveform does not exist” error is generated.
DATA:ATTRibute:CFACtor? [<
arb name>]
Query the crest factor of all data points for the specified arbitrary
waveform. Crest factor is the ratio of the peak value to the
RMS value of
the waveform. The default arb name is the arbitrary waveform
currently active (selected with FUNC:USER command).
If you query a waveform that is not currently stored in memory,
a +785, “Specified arb waveform does not exist” error is generated.
DATA:ATTRibute:POINts? [<
arb name>]
Query the number of points in the specified arbitrary waveform.
Returns a value between 8 and 16,000 points. The default arb name is
the arbitrary waveform currently active (selected with FUNC:USER
command).
If you query a waveform that is not currently stored in memory,
a +785, “Specified arb waveform does not exist” error is generated.
DATA:ATTRibute:PTPeak? [<
arb name>]
Query the peak-to-peak value of all data points for the specified
arbitrary waveform. The default arb name is the arbitrary waveform
currently active (selected with FUNC:USER command).
This command returns a value between “0” and “+1.0”, with “+1.0”
indicating full amplitude available (100%).
The maximum peak-to-peak amplitude will be limited if the data
points do not span the full range of the output
DAC (Digital-to-Analog
Converter). For example, the built-in “
SINC” waveform does not use
the full range of values between
1 and therefore its maximum
peak-to-peak amplitude is 6.084 Vpp (into 50 ohms).
If you query a waveform that is not currently stored in memory,
a +785, “Specified arb waveform does not exist” error is generated.
