User Manual 1177.6381.02 ─ 03
This manual only gives a brief introduction to the Inline Calibration System's
connection and use. For detailed information on remote operation refer to
the forthcoming Rohde
&
Schwarz Application Note.
3.1
Inserting the ICUs into the Signal Path
Each Inline Calibration Unit offers two RF connectors:
●
The female
VNA
connector is used to establish an RF connection to the VNA
(using cables, step attenuators, etc.)
●
The male
DUT
connector is used to establish an RF connection to the DUT; it
should be connected
directly to the DUT
Every cable, adapter etc. between the Inline Calibration Unit and the DUT
will be treated as a part of DUT, because the reference plane of the calibra-
tion is shifted to the DUT Port of the Inline CalU.
3.2
Connecting the ICUs to the ICC
See
Chapter 2.4, "Connecting ICUs"
3.3
Calibration Accuracy
To ensure an accurate calibration consider the following:
●
Avoid using adaptors between Inline Calibration Unit and DUT
●
After connecting the Inline Calibration Units to the Inline Calibration Controller,
allow for a sufficient warm-up time before starting the calibration
