R&S ZVH Network Analyzer Mode (R&S ZVH-K42)
Calibrating Measurements
Operating Manual 1309.6946.12 - 09 179
● Full 1-Port
For more information see "Calibration Methods" on page 46.
● Normalize Transmission
For more information see "Calibration Methods" on page 46.
● Normalize Transmission with Isolation
For more information see "Calibration Methods" on page 46.
Each calibration method is suitable for certain kinds of measurement tasks.
● For high isolation meaurements, use the normalization and isolation calibration
methods.
● For filter measurements requiring high standards (for example S11 in passband
better than -20 dB), use the full 2-port high accuracy calibration.
● For full s-parameter measurements on attenuators or amplifiers, use the full 2-port
calibration.
6.1.1.3 Performing Calibration
The procedure is similar for all calibration methods, except that you are going to need
different type and number of calibration standards. You can find an example of a full 2-
port calibration procedure in the description of the cable and antenna analyzer. For
more information see "Performing a Full 2-Port Calibration" on page 46.
Selecting a calibration kit
To avoid phase errors, you have to define the characteristics of the calibration kit you'd
like to use and then select the calibration kit in use. The R&S ZVH then corrects the
measurement results accordingly.
You can either use one of the calibration kits specifically designed for use with the
R&S ZVH, e.g. the R&S FSH-Z28 and -Z29 calibration kits. Those provide an "Open",
"Short" and "Load" calibration standard in one piece. The characteristics of these
calibration kits are already part of the R&S ZVH firmware.
You can create and edit calibration kits with the R&S ZVHView software and transfer
them to the R&S ZVH via the USB or the LAN interface. The number of standards the
R&S ZVH can store in its memory depends on the number of other data sets stored on
the R&S ZVH.
For more information see "Managing Datasets" on page 27.
► Press the CAL key.
► Press the "Cal Kit" softkey.
The R&S ZVH opens a dialog box to select the calibration kit. The list of supported
calibration kits covers those supported by the R&S ZVH and those that you have
customized.
► Select the calibration kit you are using.
The R&S ZVH uses the characteristics specified for the calibration kit.
