5. Adjust the analyzer center frequency, if necessary, to place the lower
frequency on the second vertical graticule line (one division from the
left-most graticule line).
6. On the analyzer, press Single. Wait for the completion of a new
sweep, then press the following keys:
Peak Search (or Search)
Marker, Delta
Peak Search (or Search)
Next Peak
The two markers should be on the signals near the second and tenth
vertical graticule lines (the first graticule line is the left-most).
7. If necessary, continue pressing Next Peak until the active marker is
on the right-most signal (1350 MHz).
8. Record the marker delta (∆ Mkr1) frequency reading as Test Record
entry 1 of the performance verification test record.
