Compensation function
Table 28. The E4980A provides three types of compensation functions:
OPEN compensation, SHORT compensation, and LOAD compensation.
Type of compensation
Description
OPEN compensation
Compensates errors caused by the stray admittance (C, G) of the test
fixture.
SHORT compensation
LOAD compensation
Compensates errors caused by the residual impedance (L, R) of the test
fixture.
Compensates errors between the actual measured value and a known
standard value under the measurement conditions desired by the user.
List sweep
Points: There is a maximum of 201 points.
First sweep parameter (primary parameter): Test frequency, test signal voltage, test
signal current, test signal voltage of DC bias signal, test signal current of DC bias
signal, DC source voltage.
Note
A parameter selected for one of the two
parameters cannot be selected for the other
parameter. It is not possible to set up a
combination of test signal voltage and test
signal current or one of test signal voltage of DC
bias signal and test signal current of DC bias.
Second sweep parameter (secondary parameter): None, impedance range, test
frequency, test signal voltage, test signal current, test signal voltage of DC bias signal,
test signal current of DC bias signal, DC source voltage
The secondary parameter can be set only with
SCPI commands.
Trigger mode
Sequential mode: When the E4980A is triggered once, the device is measured at all
sweep points. /EOM/INDEX is output only once.
Step mode: The sweep point is incremented each time the E4980A is triggered.
/EOM/INDEX is output at each point, but the result of the comparator function of the
list sweep is available only after the last /EOM is output.
