Test setup
 Test setup 6
Settings on R&S SML / R&S
SMV03
- PRESET
- FREQ 100MHz
- LEVEL 0 dBm
- MODULATION STEREO SOURCE LFGEN (or EXT L/R)
MODE L (or MODE R)
Setting on UPL - GEN:
- INSTRUMENT ANALOG: Channel(s) 1 (or 2)
- FUNCTION Sine
- FUNCTION Frequency = 1kHz
- FUNCTION Voltage = 0.707V
Setting on FMB - DEMODULATOR FM-STEREO
- CHANNEL L (or R)
- RELATIVE
Measurement  Set the respective LF generator (R&S SML or UPL) to 500Hz and
measure the reference level (MEAS-REF). Then traverse the LF
gen. from 20Hz to 15kHz and record the frequency response in all
four combinations (internal L, internal R, external L, external R).
