Programming the Digitizer
The digitizer function lets you access the enhanced voltage and current measurement capabilities of
the N6700C power system. You can:
Select a measurement function and range.
Adjust the measurement sample rate.
Specify a measurement window that can attenuate AC noise.
Trigger the measurement
Retrieve the measurement array data.
Select a Measurement Function and Range
The following commands select a measurement function. To enable the measurement function, use:
Front Panel Menu Reference SCPI Command
Not available To enable voltage or current measurements:
SENS:FUNC:VOLT ON, (@1)
SENS:FUNC:CURR ON, (@2)
If a power module has simultaneous measurements (refer to 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 Menu Reference SCPI Command
Select Measure\Range.
Select the lower measurement range from the voltage
or current dropdown menu. Then press Select.
To setthe 5 V measurement range:
SENS:VOLT:RANG 5, (@1)
To setthe 1 A measurement range:
SENS:CURR:RANG 1, (@1)
Seamless Measurements
Seamless measurement autoranging for both voltage and current measurements is
available on models N678xA SMU and with Option SMR.
Seamless measurement autoranging enables a wide dynamic measurement range with no data lost
when transitioning across ranges. Seamless autoranging does not include the 10 μA range, which
must be selected manually.
