Inovonics Model 540 FM Subcarrier Monitor

The Inovonics 540 accurately measures SCA RDS/RDBS and high speed data subcarriers, with a quick and easy user interface

• A tunable monitor for all digital and analog FM subcarriers.
• Measures sub injection level and demodulates SCAs.
• Optional RS-232 interface for downloading RDS/RBDS data.

The Model 540 connects to the composite/MPX output of any FM modulation monitor. Setup is simplified with a built-in calibration utility.

The 540 is tuned in 1kHz steps to display the injection level of any digital or analog subcarrier between 55kHz and 99kHz.

A dual-bandwidth IF accommodates wide and narrow subcarrier signals.

Conventional analog SCAs are demodulated to show the actual subcarrier deviation, and an RS-232 interface is optionally available for downloading and reading RDS/RBDS data groups.

Accepts MPX input; tunes and demodulates analog and data subcarriers, 55kHz-99kHz.
