Coulombs Measurements
5-5
SCPI programming
A) SENSe:FUNCtion <name>
Parameters
‘CHARge’
Coulombs function
‘CURRent’
Amps function
‘VOLTage’
Volts function
‘RESistance’
Ohms function
Note that the parameter names are enclosed in single quotes (‘). However, double quotes (“)
can instead be used. Each measurement function “remembers” its own unique range setting.
B) SENSe:DATA?
This command does not trigger a reading. It simply returns the last “raw” reading string. It
will not return the result of any instrument calculation. The reading reflects what is applied to
the input.
To return a fresh (new) reading, you can send the INITiate command to trigger one or more
readings before sending :DATA?. Details on INITiate are provided in Section 9.
While Model 6514 is busy performing measurements, the :DATA? command will not return
the reading string until the instrument finishes and goes into the idle state.
