As previously mentioned, the HP 66332A dc source has the capability of measuring output
waveform parameters such as peak, minimum, high level, and low level as illustrated in the
following figure.

Figure 5-5. Front Panel Pulse Measurement Parameters (HP 66332A only)
Use the Meter menu for making front panel measurements:
Action Display
1. For current measurements, press Shift, Input. Then press ä until you
obtain the CURR:RANG AUTO command. Press Enter to activate
autoranging. Two other selections are also available. Select the High
range when measuring currents above 20 mA. Select the Low range for
improved resolution when measuring currents below 20 mA.
CURR:RANG AUTO
2. For output waveform measurements, press Shift, Input. Then press q
until you obtain the CURR:DET command. Check to make sure that the
ACDC current detector is selected. This provides the best accuracy for
waveform measurements. Only select the DC current detector if you are
making dc current measurements and you require a dc measurement
offset better than 1mA on the High current measurement range.
CURR:DET ACDC
Note: In the Low current measurement range, the current detector is fixed at DC. With
the current detector in dc, accurate current measurements cannot be made on
waveforms with frequency contents over a few kHz.
