A16 Reference Assembly Troubleshooting
Assembly Output Signal Frequency & Amplitude Verification
With the use of a spectrum analyzer, verify the frequency and amplitude of the
different A16 Reference assembly outputs as outlined in
. In order to
measure these signals, you will need to remove the instrument dress cover
(MP24) and top brace (MP10). Refer to
Chapter 18, “Assembly Replacement
for instructions on removing these covers.
The location of the connection for each of the A16 Reference assembly signals
and the description, frequency, and amplitude of
each can be found in
