1
Once the beatnote is displayed;
a
press the press [[RANGE]]
b
press [[AUTO RANGE OFF]]
c
and press [[SINGLE AUTO RANGE]] on the RF analyzer
2
Set the span width on the RF analyzer to approximately 4 x PLL bandwidth.
Adjust the BITNET to position it near the center of the display.
a
Press the [[AVG]] key, and then the RMS key.
Wait for the trace to return and then press;
b
[[MKR]] and MKR to Peak.
3
Press [[REL MKR]], and MKR REF.

Peak tuning range (Hz)
NOTE
If you are not able to tune the beatnote to 2 X PLL bandwidth (center of display) due to
frequency drift, refer to Tracking Frequency Drift in this section for information about
measuring drifting signals. If you are able to locate the beatnote, but it distorts and then
disappears as you adjust it towards 0 Hz, then your sources are injection locking to each
other. Set the beatnote to the lowest frequency possible before injection locking occurs
and then refer to“Minimizing Injection Locking" on page 120 for recommended actions.
