Troubleshooting
In this section, a thorough discussion of the error conditions will be presented together with a
systematic step-by-step procedure for tracking down the source of the problem.
systematic step-by-step procedure for tracking down the source of the problem.
3.1
Transmitter Problem: No Signal on Screen
a) In Graph mode try the Automatic timezero search. Keep the antennas about one
antenna length apart.
b) If the error comes up “No Signal Found” then try using the Full Search option in Graph
mode timezero search to look for the pulse.
If the pulse still cannot be found do the following checks:
Make sure the transmitter battery is properly charged and connected.
Check the condition of the single fiber optic cable to the transmitter, looking for any signs of
stress or damage. Replace or repair if needed.
stress or damage. Replace or repair if needed.
Check that the brass antenna sockets in the bottom of the transmitter and the brass antenna pins
in the top of the antenna are properly tightened. Also check that there is a good contact between
them.
in the top of the antenna are properly tightened. Also check that there is a good contact between
them.
Set the system up with a time window of 1500 ns, stacks at 1024 and sampling interval at 800ps.
Unplug the grey transmitter fiber optics at the console.
Unplug the grey transmitter fiber optics at the console.
With the system running, look for a red light coming from the grey hole in the console (single
hole). Plug this cable back in and unplug the INPUT (black) cable at the transmitter. Check for a
red light coming from the cable.
hole). Plug this cable back in and unplug the INPUT (black) cable at the transmitter. Check for a
red light coming from the cable.
If the above process fails while checking the light in the cable then replace the cable.
If the above process fails while checking the light in the console, carefully remove the back from
the console unit and check the short fiber optic cables inside the unit. As a test, these short
sections of cable may be bypassed by plugging the long transmitter fiber optic cable directly into
the electronics. Replace or polish the short cable if needed.

c) If the signal is still not found, set the system up with the maximum time window (2048
ns on older systems, 32000 ns on newer systems) and stacks at one. Run in Graph
mode and use the Full Search option to look for signal. If the pulse is visible on the
trace, adjust it to the shaded region. Now you should be able to change the time
window back to the desired length and have timezero visible.
