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 ext mixer softkey can be

 

 

 

 

found under the State key.

external mixers. Twelve frequency bands are available. Table 2-2

 

 

 

 

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.
