Arbitrary Waveform Commands (Option 002)
4
DATA:ATTRibute:AVERage? [<arb name>]
Query the arithmetic average of all data points for the specified arbitrary
waveform (-1 ≤ average ≤ +1). 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 “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 “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 from 1 to 8,192 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 “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 from “0” to “+1.0”, with “+1.0”
indicating full amplitude available.
• The maximum 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 binary values between ±1 and therefore its maximum amplitude is
6.087 Vpp (into 50 ohms).
• If you query a waveform that is not currently stored in memory,
a “Specified arb waveform does not exist” error is generated.
