R&S SMB100A
Manual operation:
[:SOURce]:STEReo:EXTernal:IMPedance <Impedance>
Selects the input impedance for the external analog audio signal inputs L and R.
Parameters:
<Impedance>
Example:
Options:
Manual operation:
[: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>
Example:
Options:
Manual operation:
[: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>
