Error message Error correction
"Synthesis-extension: modulation input
level out of range"
If this message doesn’t vanish after reducing or
removing input signal, change the module.
"
Synthesis-extension: fm-offset adjustment
failed"
"Synthesis-extension: msw-ad adjustment
failed"
Try to execute Internal Adjustment “Adjust FM”
anew.
If error messages continue, change the module.
"Synthesis-extension: kvco adjustment
failed"
Check for correct input signals and cabling from
SSYN.
If input signals are correct and error message is
displayed anyhow, change the module.
"Synthesis-extension: adjustment data
invalid"
"Synthesis-extension: new adjustment data
invalid"
"Synthesis-extension: cannot initialize
adjustment data"
"Synthesis-extension: cannot initialize
adjustment pattern"
Try to execute Internal Adjustment “Adjust
Synthesis” anew.
If error message continues, although the adjustment
finished successfully, data transfer maybe disturbed.
Try to change the DACIF module.
"Synthesis-extension: cannot read
EEPROM data"
"Synthesis-extension: cannot store
adjustment data"
This indicates problems concerning the data transfer
from and to the EEPROM of the module. If changing
the module does not cure, change module DACIF .
Error Message - DACIF: PLL unlocked (100 MHz)
Error Error correction
This error message indicates that the 100
MHz PLL on the DACIF board module is
unlocked. The reference signal for this PLL
is supplied by the SYNEX A module, if
fitted. The error also occurs if this reference
signal is missing.
Connect spectrum analyzer to SYNEX A X706.
Check that frequency is 12.8 MHz and level is
correct.
Values correct: Defective connecting cable or
continue troubleshooting on DACIF board.
Values incorrect: Change module SSYN A.
Frequency Error < 2*10
-6
, Reference Oscillator adjustment
If a SYNEX module is fitted in Path A, the internal 10 MHz reference oscillator in this module is used.
Refer to module SSYN for adjustment.
