JIG FOR CHECKING BD BOARD WAVEFORM
The special jig (J-2501-196-A) is useful for checking the waveform of the BD board. The names of terminals and the checking items to be
performed are shown as follows.
GND : Ground
I+3V : For measuring IOP (Check the deterioration of the optical pick-up laser)
IOP : For measuring IOP (Check the deterioration of the optical pick-up laser)
TEO : TRK error signal (Traverse adjustment)
VC
: Reference level for checking the signal
RF
: RF signal (Check jitter)
FE
: FOCUS error
