Making Time-Gated Measurements
Generating a Pulsed-RF FM Signal
Digitizing oscilloscope setup
If you are using a digitizing oscillascope, set up the oscilloscope to view the trigger,
gate and RF signals (see Figure 8-3 for an example of the oscilloscope display):
7 Set the RBW to auto,
gate view to off, gate
method to LO, and
gate to on.
a. Press Sweep/Control, Gate, Gate
View (Off).
b. Press BW, Res BW (Auto).
c. Press Sweep/Control, Gate, Gate
Method, LO.
d. Press Gate (On).
