Initial S/W Revision
Agilent 11970
This menu allows you to preset for one of the models in the HP/Agilent 11970 series.
Because the X-Series has an LO range of 3.8 – 14 GHz, and older analyzers had an LO range of 3.0 – 6.8 GHz, the
harmonic numbers used in the X-Series may differ from those used on older analyzers for the same mixers.
Additionally, some of the 11970 mixers cannot be operated over their full range with the X-Series without
switching harmonics. Consequently, you will find that some of the bands (A-Band, for example) are broken into
two ranges for use with the X-Series.

More Information
Below are the 11970A presets. The 11970U and the 11970W use a single harmonic. The other three switch
harmonics mid-band. Both harmonic ranges are shown in the table. None of these mixers use LO doubling.
The 11970 K-band mixer and the 11974 preselected mixer series are not supported.

The [:SENSe]:MIXer:BAND command was used in PSA and ESA to select
the mixer band. In the X-Series, only the legacy parameters A, Q, U, V, and
W are honored, and they preset the analyzer to match the corresponding
Agilent 11970 legacy mixer. Parameters D, E, F, G, J, K, and Y, which were
accepted in ESA and PSA, return an error if sent. If you are using a mixer in
one of these bands, you should study the tables of presets and choose the
appropriate preset to match your application.
