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)

TEO : TRK error signal (Traverse adjustment)

VC

: Reference level for checking the signal

RF

: RF signal (Check jitter)
