Test modes
Select a test mode
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).
