Phase Lock Diagnostics

Description
This program
is not
a
test in
that It
does not verify conformance
to
a
specification. Rather it
is a
diagnostic which tests the integrity of
the Internal phase lock loops
The diagnostic causes the
phase lock loop frequency
to be switched very rapidly from one extreme
to the
next During
this process, the synthesizer
is
polled for an unlock indication
to determine
if
phase
lock has
been
lost
If
at any point during
the test an unlock
indication
is
detected, the diagnostic
will
indicate which phase lock loop
was unlocked.
