System error correction
For precise S-parameter measurements, a system error correction is recommen-
ded. System error correction requires a calibration kit that is suitable for the mea-
sured frequency range. For the R&S
ZNA67EXT we recommend the 1
mm cali-
bration kit R&S
ZV-Z210. The standards in these calibration kits allow for OSM,
TOSM, UOSM and TOM calibrations.
The characteristic data of a particular R&S
ZV-Z210 is stored on a USB stick
shipped with the kit, and must be installed manually, before the kit can be used.
With an additional reference receiver calibration at one of the converter
ports, a full n-port system error correction at n > 1 converter ports of the
same waveguide band can be extended to a SMARTerCal. A SMARTerCal
enables (relative) phase
and
(absolute) power accurate measurements of all
involved a- and b-waves.
Refer to the documentation of your calibration kit and to the R&S
ZNA help sys-
tem or user manual for more information.
9.6
Mounting a DUT
The DUT must be screwed to the 1
mm test port connector at the front of the
diplexer. A tight connection is essential to ensure precise calibration and mea-
surement results. Depending on the connectors of the DUT, possibly additional
adapters are required.
For
n
-port measurements,
n
external test sets must be connected to one DUT.
Use the adjustable feet of the test sets to align the DUT accurately.

Measurement
After power calibration and system error correction, mount the DUT (see
Measurements involving converters can be performed like other measurements.
All measured quantities (S parameters, wave quantities, ratios etc.) are available.
