HCD-C5

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.

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)
