5.7.1 Voltage, Current and Power Measurements

To the rms voltage or current, use:

MEASure:VOLTage?or

MEASure:CURRent?

To measure the maximum current amplitude, use:

MEASure:CURRent:AMPLitude:MAXimum?

To reset the peak measurement , use

MEAS:CURR:AMPL:RESet

To measure the power, use:

MEASure:POWer?

5.7.2 Returning Voltage and Current Data From the Data Buffer

The MEASure and FETCh queries can also return all 4096 data values of the instantaneous

voltage and current buffers. These are:

MEASure:ARRay:CURRent[:DC]?;*WAI

MEASure:ARRay:VOLTage[:DC]?;*WAI

5.7.3 Triggering Measurements

You can use the data acquisition trigger system to synchronize the timing of the voltage and

current data acquisition with an external trigger source. Then use the FETCh commands to

return different calculations from the data acquired by the measurement trigger.

The following measurement trigger sources can be selected:

IMMediate Aquire the measurements immediate

BUS IEEE-488 device, *TRG, or <GET> (Group Execute Trigger)

TTLTrg The signal driving the Trigger Out

5.7.4 Measurement Trigger System Model

Figure 5-2 is a model of the measurement trigger system. The rectangular boxes represent

states. The arrows show the transitions between states. These are labeled with the input or

event that causes the transition to occur.
