If the Out-of-Lock warning message appears,

verify that the voltage within the RF pulse “ON”

portion is zero volts (observed on the scope). If

phase-lock has been achieved, select Continue;

if phase-lock has not been achieved, select Re-try.

Phase lock indications include a flat zero-volt

trace (no presence of any beat note or search

signal).

7. When the measurement is complete, print the

results and save the measurement file.
