Signal Source
For model .02, an internal fixed signal source at -10 dBm is available.
For model .12, a tracking generator is available. See
Chapter 7.2.4, "Configuring the
Tracking Generator"
,
on page 152.
A typical test setup to test cables and antennas includes the R&S Cable Rider ZPH, an
RF cable (R&S FSH-Z320, order number 1309.6600.00), a calibration standard (R&S
FSH-Z28/Z29, order number 1300.7810.03 / 1300.7610.03 or R&S ZN-Z103 order
number 3586.9392.00) and the cable under test. See
Chapter 7.1.7.2, "Calibration
Methods"
,
on page 138.
Cable and antenna tests also require a signal source which is already part of the R&S
Cable Rider ZPH hardware. The signal source transmits a reference signal to the test
port.
1. Connect the RF cable to the RF input.
2. Connect the test cable to the RF cable.
3. For measurement on DUTs that need an external voltage supply (e.g. power ampli-
fiers), you can use the internal DC bias which is only available with model .12.
Select the "DC Bias" softkey.
The R&S Cable Rider ZPH opens an input field to specify the DC bias voltage.
4. Enter the desire voltage.
For more information, see
"Configuring the BIAS output port"
on page 40.
By default, the R&S Cable Rider ZPH is in the CAT mode after you have turned it on.
To switch to the CAT mode from another operating mode, proceed as follows.
1. Press the [MODE] key.
2. Select the "Antenna & Cable" softkey.
The R&S Cable Rider ZPH starts the antenna and cable test (CAT) mode.
