Manual operation: See "RDS Program Service Name - Stereo Modulation"
on page 217
[:SOURce]:STEReo:EXTernal:IMPedance <Impedance>
Selects the input impedance for the external analog audio signal inputs L and R.
Parameters:
<Impedance> 600 | 600Ohm | 100000 | 100kOhm | 100000Ohm
*RST: 100000
Example:
SOUR:STER:EXT:IMP 600Ohm
selects 600 OHM as the impedance for the external analog
audio signals.
Options: R&S SMB-B5
Manual operation: See "External R/L Impedance - Stereo Modulation" on page 214
[: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> integer
Range: 1000 to 18000
*RST: 1000
Example:
SOUR:STER:MMF 2000
sets a maximum modulation frequency of 2 kHz.
Options: R&S SMB-B5
Manual operation: See "Max Modulation Freq- Stereo Modulation" on page 215
[:SOURce]:STEReo:PILot:PHASe <Phase>
Sets the phase of the pilot tone in degrees, 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: -5 to 5
Increment: 0.1
*RST: 0
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.
