Description
Select the measurement mode for your test:
•
FDS (only): Frequency Domain Spectroscopy
(5 μHz...5 kHz)
•
PDC (only): Polarization and Depolarization
Current Method (20 μHz...99 mHz)
Combined: Combines the FDS and PDC
•
methods in one measurement
(20 μHz...5 kHz). The PDC method is used for
frequencies below the set limit by transforming
the PDC results to FDS results to reduce the
measurement time up to 75% compared to
frequency domain measurements (FDS).
1
Switching frequency between the FDS and PDC
methods
Defines the low-frequency limit of the
transformation from PDC to FDS.
Select the Do not re-calculate stable PDC data
check box if you do not want to recalculate the
PDC data when the data does not change with the
increasing time of the PDC measurement.
Select Auto to generate default frequency sweep
list.
Select Custom to specify your own frequency
sweep list.
