You can create and edit transducer factor with the R&S InstrumentView software pack-
age and then transfer them into the internal memory of the R&S Cable Rider ZPH.
Each transducer factor can consist of up to 1000 reference values.
Display of the antenna directions
An isotropic antenna consists of three orthogonal elements. Each of these elements
measures the field strength from a different direction (x-, y- and z-axis).
Decrease of measurement speed
The R&S Cable Rider ZPH performs a measurement on each of the three antenna
axes, the update rate of the results decreases slightly.
You can select to display different aspects of the measurement.
1. Select the "Meas Mode" softkey.
2. Select the "Isotropic Antenna" menu item.
The R&S Cable Rider ZPH opens a new menu to select the measurement aspect.
● "Auto"
Shows the total field strength over all three antenna axes.
The displayed result is a combination of the results for each antenna element.
After measuring each of the three directions individually, the R&S Cable Rider
ZPH calculates the total field strength (E

) based on the results for each
antenna element.

● "X"
Shows the field strength measured on the antenna's x-axis only.
● "Y"
Shows the field strength measured on the antenna's y-axis only.
● "Z"
Shows the field strength measured on the antenna's z-axis only.
Direct current output
The BNC and RF connector can be configured as in internal DC bias port to provide
direct current output for active equipment under test. When the internal DC bias port is
activated, the status of the internal DC bias connector, voltage and current setting is
displayed at the right-hand corner of the trace window.
For more information, see
Internal DC bias connection.

Configuring Spectrum Measurements
Basic measurement settings that are common to many measurement tasks, regardless
of the application or operating mode, are described here. If you are performing a spe-
cific measurement task, using an operating mode other than Signal and Spectrum Ana-
