4 Using the Measurement Functions
Agilent N678xA SMU Meter-Only Modes
NOTE
106
Seamless voltage and current measurement autoranging is available
on Agilent Models N6781A and N6782A. This enables a wide dynamic
measurement range with no data lost across ranges. Autoranging
does not include the 10 μA range, which must be selected manually.
To enable seamless voltage or current autoranging on channel 1:
SENS:CURR:RANG:AUTO ON,(@1)
SENS:VOLT:RANG:AUTO ON,(@1)
The following information only applies to Agilent Models N678xA SMU.
Agilent Models N678xA SMU can measure voltage or current at the
output terminals without involving the source function of the
instrument.
Make all measurement connections before selecting the Measure Only
functions. This is because when the Measure Only functions are
selected, the instrument goes through an initialization sequence that
minimizes the amount of disturbances imposed on the DUT. The
output is also enabled to allow the meters to measure correctly.
From the front panel
In the Source Settings window, select one of the Measure Only
functions in the Emulating dropdown list.
The Voltage Measure Only selection emulates a voltmeter. Current
priority mode is set by default. The +/- Voltage Limits are set to their
maximum values. No additional settings are required.
