Read Waveform from Oscilloscope
Reset the instrument to a known state and automatically configure the measurement parameters.
reset(dev) autoSetup(dev)
Get the actual record length, which is the number of points that the oscilloscope acquires.
recordLength = actualRecordLength(dev)
recordLength = 62500

Set the channel probe attenuation to 1.
dev.Channel("Channel1").ProbeAttenuation = 1;Specify the sweep time duration in milliseconds.
maxTimeMilliseconds = 1e3;
Read a waveform from the oscilloscope.
[waveformArray,actualPoints] = readWaveform(dev,"Channel1",recordLength,maxTimeMilliseconds);Visualize Data and Display Any Errors
Get the number elements in the waveform array and verify that they match the actual number of points returned by the readWaveform function.
n = numel(waveformArray);
Calculate the time in between samples and create a time vector.
dt = dev.Acquisition.HorizontalTimePerRecord/dev.Acquisition.HorizontalRecordLength; t = (0:n-1) * dt;
Display the waveform.
plot(t,waveformArray); grid on; xlabel('Time (s)'); ylabel('Volts (V)');
If there are any errors, query the driver to retrieve and display them.
errorNum = 1; while (errorNum ~= 0) [errorNum,errorMsg] = error_query(dev); fprintf('ErrorQuery: %d, %s\n',errorNum,errorMsg); end
ErrorQuery: 0, No error
Clean Up
Disconnect and clear the ividev object from the workspace.
