Rohde & Schwarz SML01 - Residual

Test sequence R&S®SML / R&S®SMV03
1090.3123.12 10.12 E-6
determined. The result is then referenced to 1 Hz bandwidth. The result
of this calculation is the value of the broadband noise.
Measurement - Measure the carrier power (P
T
)
- Detune the center frequency by 5 MHz
- Measure the channel power (P
K
)
Analysis The value of the broadband noise is determined from:
