Command Reference
QSZ
The current compliance polarity is automatically set to the same
polarity value as the output voltage, regardless of polarity of the
specified Icomp.
Example
Statements
OUTPUT @B1500;"QSV 1,1,0,0,5,1,4,0.1"
This example sets the following parameter values:
start=0 V, stop=5 V, cvoltage=1 V, step=4
This sets the sweep step voltage to 1 V. And the capacitance measurement is then
executed over the following voltage ranges:
1st sweep step: 0.5 to 1.5 V
2nd sweep step: 1.5 to 2.5 V
3rd sweep step: 2.5 to 3.5 V
4th sweep step: 3.5 to 4.5 V
For easy definition, use variables to set the parameters as shown below:
Start=0 !Start voltage (V)
Stop=5 !Stop voltage (V)
Cvolt=1 !C meas voltage (V)
Svolt=1 !Sweep step voltage (V)
Nop=ABS(Start-Stop)/Svolt-1 ! Number of steps
!
OUTPUT @B1500;"QSV 1,1,0,Start,Stop,Cvolt,Nop,0.1"
QSZ
This command enables/disables the capacitance offset cancel function for the
quasi-static CV measurement (MM13). Or this command triggers the capacitance
offset measurement, and returns the measurement result.
Execution
Conditions
The quasi-static CV measurement setup must be completed before executing the
offset measurement.
To execute the offset measurement, open the measurement terminals at the end of
the device side.
Syntax QSZ mode
Parameters mode : Capacitance offset cancel function. Integer expression. 0 to 2.
