Title: L-Band Satellite Level Monitor
Category: Digital Products
Industry: TV/Radio Broadcast, CATV Cable Industry,
Description:
The SLM-771 is an L-Band Satellite Level Monitor designed to detect measure and report the receiving level of any RF signal from 5MHz up to 2.5GHz. Use it for early warning of satellite dish and LNB signal degradation due to snow loading, bug & bird intrusions, dish misalignment due to wind or movement, and any increase in LNB loss for whatever reason. It will alert you to the signal reduction before a system failure occurs.
It has both visual and telemetry voltage outputs calibrated in dB steps and an audible alarm with a relay contact for activation of external alarms or other equipment.
The front panel LED indicators are calibrated in 1dB steps for accurate loss detection. A front panel control is used to set up the monitor and alarm level.
The meter output has a voltage that changes 100mV per 1 dB and is field adjustable for offset to match your telemetry transmission equipment. +/- 0.0 to 10 Volts is available at the meter output. The unit is fully RF shielded and can be mounted in the front or rear of your rack.
