User Manual 1321.0950.02 ─ 07

Reference Deviation

The reference deviation is available only in the FM domain, the maximum of reference
deviation setting is (demodulation bandwidth) /2.

1. Press [DTF/BW] key.

2. Select the "Reference Deviation" softkey.

The R&S Cable Rider ZPH opens an input field to select the reference deviation.

3. Select the reference deviation you require.

See 

Table 12-1

 .

Audio Lowpass

The "Audio Lowpass", a DPD (Digital Predistortion) designed filter is used to fine-tuned
the measurements demodulated signals.

1. Press [MEAS] key.

The R&S Cable Rider ZPH opens the analog modulation measurement menu.

2. Select the analog modulation domain you require, "AM Domain" or "FM Domain"

softkey.

3. Select the "Audio Lowpass" softkey

A drop-down menu to select the audio lowpass filter opens.

4. Select the audio lowpass filter you require.

See 

Table 12-3

.

12.1.3.5

 

Defining FM Broadcast

Depending on the country-specific requirements, it maybe necessary to suppress the
display of higher frequency component of the modulation signal.

FM Broadcast

The FM broadcast is only enabled with the 

demodulation bandwidth

 setting at 200 kHz

or 300 kHz.

1. Press [DTF/BW] key.

2. Select the "FM Broadcast" softkey.

A drop-down menu to select the filter opens.

3. Select the filter setting you require.
