Preselector (Option 123)

Adjust

Allows you to manually adjust the preselector filter center frequency to optimize its

response on the signal of interest. When enabled, the center frequency must be set to

3.045 GHz or greater.

Limits are: –250 MHz to 250 MHz.

PreSelector Enabled

Enables or disables the preselector.

Enabled: Can be set if the Center Frequency is greater than 3.045000000 GHz.

Possible Values: Enabled, Disabled

Peak

Performs a peak search.

Enabled: Can run if Center Frequency is greater than 3.045000000 GHz.

Instrument Functions: A - L

External Mixer

Selects either the internal mixer or an external mm-wave mixer.

• When Internal mixing is selected, normal operation and all other external mixing

functions are unavailable.

• When External mixing is selected, you can analyze high frequency signals (that is,

higher than the spectrum analyzer’s maximum frequency) by using an appropriate

external mixer.

Band Selects a band, or sets the frequency band to be user defined.

User Defined values:

• K - 18 to 26.5 GHz

• A - 26.5 to 40 GHz

• Q - 33 to 50 GHz

• U - 40 to 60 GHz

• V - 50 to 75 GHz

• E - 60 to 90 GHz

• W - 75 to 110 GHz

• F - 90 to 140 GHz

• D - 110 to 170 GHz
