5 Troubleshooting
5.1 Input
 TS1 ERROR
 Alarm message
 LCD: TS1 ERR
 LED_ TS1: Off
 LED_ TSErr: On
 Cause: Input signal from port [TS_IN_1] is lost or has invalid format.
 Solution: Check connection of port [TS_IN_1], and make sure input signal has valid
format.
 TS2 ERROR
 Alarm message
 LCD: TS2 ERROR
 LED_ TS2: Off
 LED_ TSErr: On
 Cause: Input signal from port [TS_IN_2] is lost or has invalid format.
 Solution: Check connection of port [TS_IN_2], and make sure input signal has valid
format.
 Transport Stream Rate Overflow or Underflow
 Alarm message
 LCD: TS_RATE Overflow
 Cause: The input TS bit rate is higher than the bit rate required
 Solution: Adjust the TS input bit rate. Or connect all devices with the same reference
clock (GPS).
Note:
The exciter has bit rate auto-adaptation function to deal with the bit rate mismatch. It
will automatically delete null packets or insert null packets when necessary to achieve
the accurate acquired bit rate.
5.2 ADPC
 Feedback Signal Level
 Alarm message
 LCD: " FEEDBACK TOO BIG! Press Any key to Esc"
Or " FEEDBACK TOO SMALL! Press Any key to Esc"
 LED_ SysErr: Flashing (during the ADPC process)
 Cause: Feedback signal level is too high or too low.
 Solution: Cancel the ADPC function manually and then adjust the input level of the
feedback signal according to the messages on the LCD. Start the ADPC function again
after the problem is resolved.
Note:
The acceptable range of feedback signal from port [RF_IN_A] or [RF_IN_B] is -30
