Manual operation: See "RDS Program Service Name - Stereo Modulation"

[:SOURce]:STEReo:EXTernal:IMPedance <Impedance>
Selects the input impedance for the external analog audio signal inputs L and R.
Parameters:
<Impedance> 600 | 100000
Range: 100kOhm to 600Ohm
*RST: 100kOhm
Example:
SOUR:STER:EXT:IMP 600Ohm
selects 600 OHM as the impedance for the external analog audio
signals.
Options: Option R&S SMB-B5
Manual operation: See "External R/L Impedance - Stereo Modulation" on page 183
[:SOURce]:STEReo:MMF <Mmf>
Sets the maximum possibly used modulation frequency. This setting is only effective for
external modulation source and activated preemphasis. It prevents over modulation but
result in a decreased s/n ratio.
Parameters:
<Mmf> float
Range: 0.00 to 18.0kHz
Increment: 0.01Hz
*RST: 1kHz
Example:
SOUR:STER:MMF 2000
sets a maximum modulation frequency of 2 kHz.
Options: Option R&S SMB-B5
Manual operation: See "Max Modulation Freq- Stereo Modulation" on page 184
[:SOURce]:STEReo:PILot:PHASe <Phase>
Sets the phase of the pilot tone in relation to the 38 kHz carrier signal of the receiver. For
a correct demodulation, the pilot tone must be in phase with the 38 kHz carrier.
Parameters:
<Phase> float
Range: -4.0DEG to +5.0DEG
Increment: 0.1DEG
*RST: 0DEG
Example:
SOUR:STER:PIL:PHAS .2DEG
decreases pilot tone quality by adding a phase difference of 0.2
degrees between pilot signal and receiver carrier signal.
