ADVANCED_MEASUREMENTS_MDO3XXX
The ADVANCED_MEASUREMENTS_MDO3XXX node extracts waveform measurements from an MDO3xxx oscilloscope.This node is similar to MEASUREMENTS_MDO3XXX node but more measurements
are availble. The available measurements are as follows:
amplitude, area, burst, carea, cmean, crms, delay, distduty, extinctdb,
extinctpct, extinctratio, eyeheight, eyewidth, fall, frequency, high, hits,
low, maximum, mean, median, minimum, ncross, nduty, novershoot, nwidth,
pbase, pcross, pctcross, pduty, peakhits, period, phase, pk2pk, pkpkjitter,
pkpknoise, povershoot, ptop, pwidth, qfactor, rise, rms, rmsjitter,
rmsnoise, sigma1, sigma2, sigma3, sixsigmajit, snratio, stddev, undefined,
waveforms
Also available are 5 statistic modes:
instant, mean, max, min, and stdev where instant is a single measurement
and stdev is the standard deviation of the mean.
Requires a CONNECTION_MDO3XXX node at the start of the app to connect with
the instrument. The VISA address will then be listed under 'connection'.
This node should also work with compatible Tektronix scopes (untested):
MDO4xxx, MSO4xxx, and DPO4xxx. Many of the advanced measurements are likely
to not function with different model numbers.Params:connection : VisaConnectionThe VISA address (requires the CONNECTION_MDO3XXX node).channel : intThe channel with which to create a measurement for.measurement : strThe measurement to make.statistic : strThe type of statistic to take for the measurement.Returns:out : DataContainerScalar: The measurement from the oscilloscope channel.
