Data Variable and Analysis Function
Data Variable
You can get the measurement results by using the measurement result names. If the
corresponding SMU or VMU does not perform a measurement, invalid data is
returned.
Output data of PGU
The data variables for PGU output are as follows:
Time data of sampling measurement
@TIME
is the data variable for time data of sampling measurement.
Index of the measurement result data
@INDEX
is the data variable for index number of measurement data.
The index number of the first data is 1. For a subordinate sweep measurement, the
index number continues to increment by 1 between secondary sweep steps, that is,
• last data of a primary sweep: index
• first data of next primary sweep: index +1
Set data Data variable name
pulse peak VNAME for PGU that you defined on CHANNELS: CHANNEL
DEFINITION screen is the data variable name for pulse peak voltage.
pulse period @PGT is the data variable for pulse period.
pulse duration @PGD is the data variable for duration time of pulse stress force.
Duration time is the pulse count multiplied by pulse period.
pulse delay
time @PG1DL is the data variable for pulse delay time of PGU1.
@PG2DL is the data variable for pulse delay time of PGU2.
pulse width @PG1W is the data variable for pulse width of PGU1.
@PG2W is the data variable for pulse width of PGU2.
pulse base @PG1B is the data variable for pulse base voltage or current of PGU1.
@PG2B is the data variable for pulse base voltage or current of PGU2.
pulse leading @PG1LD is the data variable for leading-edge transition time of PGU1.
@PG2LD is the data variable for leading-edge transition time of PGU2.
pulse trailing @PG1TR is the data variable for trailing-edge transition time of PGU1.
@PG2TR is the data variable for trailing-edge transition time of PGU2.
