:CALibrate Calibrator Commands
The :CALibrate Calibrator commands control the CAL OUT and AUX OUT outputs on the front of the oscilloscope.
These two outputs share the same AC signal generator, but the CAL OUT has a DC offset while AUX OUT does not. This means that AUX OUT cannot be used in any DC mode. AUX OUT will always be a negative amplitude AC signal. AC signals on CAL OUT are level-shifted to be centered around 0 V.
