lnovonics’ 530 answers the very real need for a simple, yet accurate and affordable FM “Mod-Monitor.” It combines a wideband FM receiver with very linear demodulation and metering circuitry for precise measurement of FM broadcast carrier modulation.
High-resolution displays give reliable readings of Total Modulation, demodulated Program Audio, and Pilot/Subcarrier injection levels. The incoming RF signal and multipath distortion components are also monitored to ensure that indicated measurements are truly valid.
-87-108MHz continuous coverage with 8 station presets.
Rear-panel BNC connector and IN/OUT switch permit external monitoring of baseband signal from off-air source, or provide input to stereo demod and metering for external baseband feed. Approx. 2 volts p-p corresponds to 100% modulation. 75-ohm output Impedance; lOk-ohm input characteristic.
Amplitude response of demodulated Composite signal: +0, -0.5dB. 10Hz-60kHz; less than 1.5dB down at 100kHz.
Dual displays show Left, Right, Stereo Sum, Stereo Difference. 19kHz Pilot, 38kHz Residual, Multipath Distortion and RF Signal Level. Quasi-peak response on +lOdB to -39dB scale, averaging response with additional 30dB gain on -2OdB to -69dB scale. ldB/step metering resolution.
Measurements, Indicators and alarms are brought-out to a rear-panel DB-25 connector so that any monitoring function may be duplicated at a remote location.
-105-130VAC and 210-260VAC, 50/60Hz; 15W.
-3.5”H x 19”W x 12”D (2U): 11 Ibs.
