Power Detector; Common Queries - Comtech EF Data LPOD Series Installation And Operation Manual

The following parameters can be user defined to report an alarm condition, a fault condition, or the parameter can be ignored completely
by masking it:
•
RF amplifier low output power (user adjustable value).
•
Internal reference oscillator unlocked.
•
*LNB current outside specified window.
•
*LNB voltage out of tolerance.
*If this parameter generates a fault condition, the RF output will be muted.

5.2.5 Power Detector

A power detector is provided to monitor the output power. It has a useful range of over 20 dB, referenced to the unit's rated P1dB point. Its
value can be read by executing the RMS query. The test data supplied with each unit gives an indication of the accuracy and flatness of
the power monitor over the frequency band of operation.

5.2.6 Common Queries

The most common queries are:
•
RMS (Retrieve Maintenance Status) – Returns voltages, fan speeds, heatsink temperature, output power monitor reading, etc.
•
RCS (Retrieve Configuration Status) – Returns current attenuation, mute, amplifier, online, etc. status.
•
RAS (Retrieve Alarm Status) – Returns current alarm or fault status.
