START-UP
The oscilloscope automatically performs a set of diag-
nostic tests
each
time it
is
turned
on.
These tests warn
the user of
any
available indication that the instrument
may
not
be
fully functional. The tests
run
for several
seconds after power is applied. If no faults are encoun-
tered, the instrument operates normally. A failure of
any
of
the power-up tests will
be
indicated
by
either a flashing
TRIG'D indicator
on
the instrument front
panel
or a
bottom-line readout
on
the CRT
in
the form: TEST XX
FAIL
VY
(where
XX
is
the test number
and
YY
is
the
failure code of the failed test).
If a failure of
any
power-up test occurs, the instrument
may
still
be
usable for
some
applications. To operate the
instrument after a power-up test failure, press the A/B
TRIG button (or A/B
MENU).
Even
if the instrument then
functions for your particular measurement requirement, it
should
be
repaired
by
a qualified service technician at the
earliest convenience. Additional information
on
the power-
up tests
and
troubleshooting
may
be
found
in
the "Mainte-
nance" section of this
manual.
Consult your service
department, your local Tektronix Service Center, or
nearest Tektronix representative if additional assistance
is
needed.
