Troubleshooting the Analyzer
● Logic levels in this chapter are either TTL level high or TTL level low
unless stated otherwise. Toggling signal levels continually change
from one TTL level to the other.
● Configure a logic probe with an external bias supply for testing digital
signals. This analyzer does not have easily accessible +5 V supplies.
● If you abort a self test before the self test is finished, the analyzer may
fail its calibration routine. To prevent this from happening press
[
Preset] or cycle power after you abort the self test.
● The troubleshooting tests in this chapter assume only one
independent failure. Multiple failures can cause false results.
