M2.2R Analog SCA and AM Measurements

Overview. The M2.2R adds extended FM analog monitoring capabilities to the M2.0X including peak­type measurements of the injection level for 19kHz pilot, 38kHz, 57kHz, 67kHz and 92 kHz sub-carriers
using the Carrier Modulation LED display with a 0.2% resolution between 4.4% and 10.4%. A rear
panel MPX Output for external sub-carrier decoding is also included. The M2.2R also adds a relative
indication of the incidental AM noise component of the FM carrier using the top Demodulation Level
LED display. During the AM noise and Sub-Pilot measurements, all other M2.0X functions are
disabled.

AM Noise Level. A relative measurement of the incidental AM noise component of the FM carrier can
be made by first tuning to the FM station of interest and then selecting AMN mode by pressing the
Demodulation Level Select switch until the blue AMN LED illuminates. The top Demodulation Level
LED meter will indicate the relative level of the incidental AM noise component present in the FM
carrier. The 0dB indication is referenced to –50dB.

Pilot and SCA Injection Level. The injection level for 19kHz pilot, 38kHz suppressed stereo
subcarrier, 57kHz SCA, 67kHz SCA and 92kHz SCA of an analog FM signal can be accurately
measured using the Carrier Modulation LED display by first tuning to the FM station of interest and then
selecting the Sub-Pilot mode by pressing the Carrier Modulation Select switch until the blue Sub-Pilot
LED illuminates. The received RF signal level of the analog FM signal must be at least 65dBf for the
Sub-Pilot mode to be active.
