4.6 Measuring with More Than One Condition (Multi-measurement)

measurement in the step.
Selectable parameters in multi-measurement
In multi-measurement, only some main settings are recalled from the setting memory.
The following settings are recalled in multi-measurement.
Signal level (voltage value, constant current value, CV, and CC)
Internal DC bias voltage
Measurement range (including Auto and Rdc range)
Trigger delay time
Measurement speed
Measurement parameters (type and equivalent circuit of primary parameter, and type of secondary
parameter)
Comparator function
Lower and upper limit of the primary parameter for limit comparison (= Lower and upper
limit of BIN 1)
Lower and upper limit of the secondary parameter for limit comparison
When a setting memory with no data is specified, the previous setting is held.
OPEN/SHORT/LOAD correction in multi-measurement
When the multi-measurement is enabled, the correction value is measured and the correction is
performed at DUT measurement as follows.
When the spot correction is disabled
The global correction value (or standard value) is measured, and the correction is performed
using it.
When the spot correction is enabled
When the correction value is measured, the frequency, main settings, and spot correction value
(and standard value) are recalled for each step that is registered in the multi-measurement list,
and the new spot correction value (or standard value) is measured to be saved in the correction
value memory corresponding to the step. The global correction value (and standard value) on the
correction value memory is held as the previous value.
When the DUT is measured, the spot correction value (and standard value) is recalled from the
correction value memory corresponding to each step. The global correction value (and standard
value) is not recalled. When no valid spot correction value is saved in the correction value
memory, the current global correction value (and standard value) is used for correction.
Unlike usual measurement, the OPEN/SHORT/LOAD correction is not disabled in each step
even when the frequency changes.
