2.29.12 Measurement of CARRIER/NOISE RATIO (DIAG-C/N MEAS)
The submenu DIAG - C/N MEAS can only be called with the option SMIQB17 (Noise generator and
distortion simulator). For C/N measurements in servicing the generator can be set to the service modes
as far are concerned. The carrier/noise ratio can then be easily determined this way. The submenu
DIAG - C/N MEAS offers an access to these modes.
