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.
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)
GND : Ground
TE
: Tracking error signal (Traverse adjustment)
FE
: Focus error signal
VC
: Reference level for checking the signal
RF
: RF signal (Check jitter)
