4 Using the Measurement Functions
From the remote interface:
Use the following SCPI commands to enable seamless measurements:
SENS:CURR:RANG:AUTO ON,(@1)
SENS:VOLT:RANG:AUTO ON,(@1)
N678xA SMU Meter-Only Modes
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 necessary
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.
When the Measure Only modes are selected, the output is enabled to allow the meters to measure
correctly. The voltage or current measurement is continuously displayed on the Meter View. Both
voltage and current meters are active in either mode.
From the front panel:
In the Source Settings window, the Voltage Measure selection emulates a voltmeter. Current priority
mode is set by default. The +/- Voltage Limits are set to their maximum values. The voltage
measurement cannot exceed the voltage ratings of the unit as indicated in the +/- Voltage Limit fields.
