1 ST LO OUTPUT
The 1st LO OUTPUT provides a nominal + 5 dBm signal that is tunable from 2.3214-6.1214 GHz. Since the
HP 8566B is synthesized, the 1st LO can be used as a precise tunable microwave source.
Example
Using the 1st LO OUTPUT as a precision source; connect equipment as shown:
Instrument Preset: (ZJ
Select zero span with: ('"ZY ]
0
Offset IF with:
By pressing (ii%-], you now have a precision source that can be tuned from 2.3214-6.1214 GHz with 1 Hz
resolution.
Example
Using the 1st LO OUTPUT as a tracking signal source from 2 - 5.8 GHz; connect equipment as shown:
Instrument Preset: @J
Set START/STOP FREQ: @ 2 GHz, @ 5.8 GHz.
The dynamic range will depend on the conversion loss and isolation characteristics of the mixer. Flatness variations
can be normalized through trace arithmetic.
