Instrument Calibration
The analyzer provides a wide range of sophisticated calibration methods for all types of measurements.
Which calibration method is selected depends on the expected system errors, the accuracy
requirements of the measurement, on the test setup and on the types of calibration standards available.
In the following we assume that the calibration kit ZV-Z21 contains an appropriate male short standard
with known physical properties. With a single short standard, it is possible to perform a normalization,
compensating for a frequency-dependent attenuation and phase shift in the signal path.
Due to the analyzer's calibration wizard, calibration is a straightforward, menu-guided process.
1. Unscrew the DUT and connect the male short standard from calibration kit ZV-
Z21.
2. In the CHANNEL keypad, press CAL to open the calibration menu.
3. Activate Start Cal – One Port P1 – Normalization (Short) to open the calibration
wizard for the selected calibration type .
4. In the first dialog of the wizard, select the calibration kit (here: ZV-Z21) and the
test port connector (here: N 50
Ω
(f), corresponding to a male calibration
standard), and click Next .
