5.11.5 METAS Cal tab

The controls on the "METAS Cal" tab allow you to set up the instrument for real-time

measurement uncertainty analysis. It is only visible if option R&S ZNB-K50 "Measure-

ment Uncertainty Analysis" and METAS VNA Tools (version 2.2.3 or higher) are instal-

led on the instrument.

For background information, see Chapter 4.7.7, "Measurement uncertainty analysis",

on page 247.

For the R&S ZNBT, the "Measurement Uncertainty Analysis" option is not availa-

ble.

●

If external switch matrices are used, measurement uncertainty analysis is not sup-

ported.

●

METAS calibration and verification is not fully supported via remote control. Some

actions must be performed from the VNA GUI.
