Chapter 4 Remote Interface ReferenceArbitrary Waveform CommandsDATA:ATTRibute:AVERage? []Query the arithmetic average of all data points for the specifiedarbitrary waveform. The default arb name is the arbitrary waveformcurrently active (selected with FUNC:USER command).œ 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? []Query the crest factor of all data points for the specified arbitrarywaveform. Crest factor is the ratio of the peak value to the RMS value ofthe waveform. The default arb name is the arbitrary waveformcurrently active (selected with FUNC:USER command).œ 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? []Query the number of points in the specified arbitrary waveform.Returns a value between 8 and 16,000 points. The default arb name isthe arbitrary waveform currently active (selected with FUNC:USERcommand).4œ 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? []Query the peak-to-peak value of all data points for the specifiedarbitrary waveform. The default arb name is the arbitrary waveformcurrently active (selected with FUNC:USER command).œ This command returns a value between “0” and “+1.0”, with “+1.0”indicating full amplitude available (100%).œ The maximum peak-to-peak amplitude will be limited if the datapoints do not span the full range of the output DAC (Digital-to-AnalogConverter). For example, the built-in “SINC” waveform does not usethe full range of values between –1 and therefore its maximumpeak-to-peak amplitude is 6.084 Vpp (into 50 ohms).œ If you query a waveform that is not currently stored in memory,a +785, “Specified arb waveform does not exist” error is generated.181
