Preselector Peaking

1. Place the active marker on the desired signal to be peaked.

Hint: To complete the preselector-peaking routine more quickly, place the signal at
center screen and reduce the frequency span until the sweep time is approximately
100 ms.

2. Peak the desired signal by using the following key sequence.

External-Mixing Functions

ext mixer

allows access to the following softkey functions that control the
measurement range when an external mixer extends the
spectrum-analyzer frequency range. The

specify the frequency range for measurements made with external
mixers. Twelve frequency bands are available.

lists the

start and stop frequencies of each band and also shows which
local-oscillator harmonic (N) is used for the mixing process. Once a
band is selected, the frequency range is locked and the spectrum
analyzer tunes with the local-oscillator harmonic for that band only.
(Selecting a new band presets the instrument in that band.)
