Epoch II fiber optic signal

Anyone know how to measure if the correct light signal is being received from the fiber optic sensors. All cables appear to be good and by using a flash light the light can be seen from the transmit cable through to the receive cable. Any instruction or troubleshooting tips on this would be Greatly appreciated......

I would suspect a fella could flip his meter to frequency and measure each quadtrature/phase signal.

We got it fixed. Someone that has had some prior experience helped us out. When the transmit and receive crystals are perfectly aligned you can see a red light on the receive end. Incredibly sensitive adjustment though.

Postal, I agree that it should be simple to measure the signal with the meter. Just don't know where to place the meter lead. If someone out there knows how to measure the signal on the board please share. Thanks......
