RF input port is calibrated for measurements on that port. The calibration proce-
dure requires no calibration standards as the R&S Cable Rider ZPH calibrates an
open connection only.

Only available with model .12.
Both RF ports are calibrated for transmission measurements. The calibration rou-
tine requires only a through connection. In the subsequent measurement, the isola-
tion between the test ports is not taken into account, a possible cross-talk between
the test ports in the test setup is not eliminated.
User calibration
After a user calibration is performed, the R&S Cable Rider ZPH allows you the option
to select applying user calibration (cal or norm) or factory calibration (dcal) data on the
measurement.
1. For model 02. press the [CAL] key.
For model 12, press the [CAL/SPAN] key.
2. Select the "User Calibration" softkey.
Depending on the current calibration state. the R&S Cable Rider ZPH toggle
between the user calibration (cal or norm) and factory calibration (dcal) state.
Note: The calibration state is displayed at the top right-hand corner on the trace
window. See
Chapter 7.1.7.1, "Calibration States"
,
on page 138.
Calibration unit, R&S ZN-Z103
Equipped with the calibration kit, R&S ZN-Z103, you can perform an automatic "Full 1-
Port" calibration across the entire frequency range. Unlike the manual calibration, this
calibration unit performs the calibration standard open, short and load to RF input of
the R&S Cable Rider ZPH without making any connection change during the calibra-
tion procedure.
Detection of the calibration kit is by means of the USB interface connection to the R&S
Cable Rider ZPH. See
Figure 7-8
.
When the calibration kit is detected, the R&S Cable Rider ZPH displayed the informa-
tion in the

1. For model 02. press the [CAL] key.
For model 12, press the [CAL/SPAN] key.
The R&S Cable Rider ZPH displayed the message "Calibration unit detected".
