microSD Card
On the rear of the R&S ZN-Z152 and R&S ZN-Z153 calibration units, there is a
microSD card slot. The microSD card can be used to store user characterization
data. The factory data is always stored on the internal memory.
●
Use the microSD card shipped with the calibration unit, if possible.
●
Before removing or inserting the microSD card, disconnect the USB
connection between calibration unit and network analyzer.

Introduction
A calibration unit enables the automatic calibration of several network analyzer
ports in one simple procedure. It contains calibration standards that are electroni-
cally switched by the analyzer firmware, when a calibration is performed. The
characteristic data of these standards is stored in the calibration unit, so that the
analyzer can calculate the error terms and apply the calibration without any fur-
ther input.
Automatic calibration is faster and less error-prone than manual calibration:
●
There is no need to connect calibration standards manually, which is particu-
larly time-saving if you want to calibrate multiple ports.
●
Invalid calibrations due to operator errors (e.g. wrong standards or improper
connections) are almost excluded.
●
There is no need to handle calibration kit data.
●
The internal standards do not wear out because they are switched electroni-
cally.
Scope of this document
This User Manual gives a brief introduction to the unit’s connection and use. For
detailed information, refer to the help system of your network analyzer.
The R&S
ZN-Z15x calibration units differ in the number of calibration ports and
the connector types. For an overview, refer to the data sheet.
