Measuring Output Pulses (Agilent 66312A, 66332A Only)

Current Detector

Check that the current detector is set to ACDC when measuring current pulses or other waveforms with a frequency content greater than a few kilohertz.

SENSe:CURRent:DETect ACDC

Only select DC as the measurement detector if you are making only DC current measurements and you require a measurement offset better than 2mA on the High current measurement range. Note that this selection gives inaccurate results on current waveforms that have ac content.

SENSe:CURRent:DETect DC

Pulse Measurement Queries

The dc source has several measurement queries that return key parameters of pulsewaveforms as shown in Figure 3-4.

FETC:CURR:MAX?

FETC:VOLT:MAX?

FETC:CURR:HIGH?

FETC:VOLT:HIGH?

FETC:CURR:LOW?

FETC:VOLT:LOW?

DATA POINTS

FETC:CURR:MIN?

FETC:VOLT:MIN?

Figure 3-4. Measurement Commands Used to Return Pulse Data

To return the maximum or minimum value of a pulse waveform use the following commands. Note that the data points of the measurement sample may not coincide with the actual maximum or minimum point on the waveform.

FETCh:VOLTage:MAXimum? or

FETCh:VOLTage:MINimum?

FETCh:CURRent:MAXimum? or

FETCh:CURRent:MINimum?

The average value of the high level or low level of a pulse can also be measured. To return the average value of the high level, use:

FETCh:CURRent:HIGH? or

FETCh:VOLTage:HIGH?

To return the average value of the low level, use:

FETCh:CURRent:LOW? or

FETCh:VOLTage:LOW?
