JIG FOR CHECKING BD (MD) BOARD WAVEFORM
The special jig (J-2501-196-A) is useful for checking the waveform of the BD (MD) 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)
TE
: TRK error signal (Traverse adjustment)
VC
: Reference level for checking the signal
RF
: RF signal (Check jitter)
FE
: Focus error signal
