Unit Function
NOTICE: See the MMI Commands manual for additional informa-
tion on commands and parameters.
ATCC Monitoring:
• Cavity status.
• ATCC Heartbeat signal: heart beat signal is repeated every 30 s.
Alarms:
• Software corrupted.
•
Distance between two channels below 150 kHz.
• Cavity VSWR alarm.
• Master Slave communication error.
• Motor alarm.
• Cavity tuning error alarms together.
• VSWR exceeded the specified value.
• Unable to park cavity.
• Cavity unable to tune to the current frequency in 3 attempts.
Controls:
• Cavity tune timeout: establishes a timeout period between a fine-tuning of
the cavities. All cavities must be fine-tuned at the timeout.
• Park a cavity: instructs the ATCC to park the specified cavity. This in-
volves adjusting the cavity resonance to a frequency outside of the Tx
band. If RF power is present, the cavity parks and then re-tunes to the in-
put frequency.
• VSWR Alarm Threshold: establishes a threshold for enabling a VSWR
Alarm. Valid threshold values are in the range 1.00 to 10.00 where 1.00
means No VSWR.
Recommended values for each MTS configuration are:
- 400 MHz: 3.00
- 260 MHz: 3.00
- 800 MHz: 4.00
DPM (Duplexer,
Post Filter)
Monitoring:
• Forward power on a digital power monitor: the input power range is from
0 W to 150 W.
• Reverse power on a digital power monitor: the input power range is from
0 W to 40 W.
• VSWR from a DPM.
• DPM temperature.
• DPM Heartbeat signal.
Alarms:
• SW is corrupted or unable to initialize.
