Calibrating the Instrument
Calibration (system error correction) is the process of eliminating systematic,
reproducible errors from the measurement results. E.g., in the current test setup,
the connecting cables between the analyzer ports and the DUT introduce an
attenuation and a phase shift of the waves. Both effects impair the accuracy of
the S-parameter measurement.
The analyzer provides a wide range of sophisticated calibration methods for all
types of measurements. The calibration method to select depends on the expec-
ted system errors, the accuracy requirements of the measurement, on the test
setup and on the types of calibration standards available.
The following example requires a calibration kit with a male Through standard
with known transmission characteristics for the related test port connector type
and gender. With a single Through, it is possible to perform a transmission nor-
malization, compensating for a frequency-dependent attenuation and phase shift
in the signal paths.
Due to the R&S
ZNLE's calibration wizard, calibration is a straightforward, guided
process.
1. Replace the DUT by the Through standard of your calibration kit. Make sure to
disconnect all calibration units.
2. Select [Cal] > "Start... (Manual)" to open the "Calibration Setting" wizard.
3. Select the port combination Port 1 (P1) and Port 2 (P2) and the calibration
type "Trans Norm". Make sure to define port 1 as the source port.
