Chapter 5 Troubleshooting
There is no signal response.
Verify that the power is switched on and all
connections are secure.
Verify the proper terminating resistor is installed if
using a Voltage measurement device.
Verify that the optical signal wavelength is within
the specified wavelength range.
Verify that the optical signal is illuminating the
detector active area.
Output voltage will not
increase or detector output is
skewed.
Check to make sure the detector is not saturated.
Refer to the Output Voltage spec in Chapter 6.
Install a 1" Lens Tube (SM1L10) to the thread
coulpler (SM1T1) to baffle any external light
sources to see if this improves the response.
