Measuring the output

All measurements are based on acquiring and subsequently processing output waveform information. When the ac source is on, it takes measurements and updates the front panel meter continuously. The Meter key accesses the measurement functions from the front panel.

The SCPI MEASure command acquires new waveform information each time it is executed. The SCPI FETCh command does not acquire new waveform information but extracts the desired information from previously acquired waveform data. SCPI commands let you measure phases individually or simultaneously measure all phases using the FETCh command.

Measurement functions

The following example illustrates the measurements that can be returned by the front panel of the ac source when sourcing power to a typical non-resistive load such as a power supply. The ac source output voltage and current waveforms are shown on the next page.

NOTE: On Agilent 6811B, 6812B, and 6813B units, the Input key selects the meter coupling and hence, what the meter will measure. The choices are: AC only, DC only, or AC + DC.
