Using the Digitizer
NOTE
The Digitizer functions described in this section are not available on all models.
Refer to the Test Extensions feature under “Model Differences” in chapter 1.
The digitizer function lets you access the enhanced voltage and
current measurement capabilities of the power system. You can:
 Specify a measurement function and range.
 Adjust the measurement sample rate.
 Select a measurement window that can attenuate AC noise.
 Retrieve arrays of the digitized current or voltage measurement.
 Synchronize measurements using trigger signals.
NOTE
When a remote interface measurement is in progress, the front panel display
may indicate “-- -- -- -- --“. Front panel measurements resume when the remote
measurement completes.
Programming the Digitizer
Select the Measurement Function and Range
The following commands select a measurement function. To enable
the measurement function, use:
Front Panel: SCPI Command:
Not Available To enable voltage measurements:
SENS:FUNC:VOLT ON, (@1)
To enable current measurements:
SENS:FUNC:CURR ON, (@2)
If a power module has simultaneous measurements (see chapter 1,
“Model Differences”), you can enable BOTH voltage and current
measurements on the same output channel.
Some power modules also have multiple measurement ranges.
Selecting a lower measurement range provides greater measurement
accuracy, provided that the measurement does not exceed the range.
To select lower measurement ranges, use:
Front Panel:
SCPI Command:
Select Measure\Range.
Select the lower measurement
range from the voltage or current
dropdown menu. Then press Select.
To set the 5 V measurement range:
SENS:VOLT:RANG 5, (@1)
To set the 1 A measurement range:
SENS:CURR:RANG 1, (@1)
