JIG FOR CHECKING BD BOARD WAVEFORM
The special jig (J-2501-149-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)
TE : Tracking error signal (Traverse adjustment)
VC : Reference level for checking the signal
RF : RF signal (Check jitter)
FE : Focus error signal
