5.9. MEASure

Measure commands return back the output voltage, current, power or temperature. They trigger the acquisition of new data before returning the reading. Measurements are performed by digitizing the instantaneous output voltage, current or temperature. Output power is calculated as product of measured voltage and current. Keyword [:DC] is optional since all measurement are by default of the DC level of the signal.
