General Description of External-Mixing Functions

NOTE

There are two different types of external mixers available, preselected and
unpreselected. The

EXT MXR PRE UNPR

softkey function applies only to the

selection of the type of external mixer to be used. It does not switch the
analyzer from internal to external mixing.

NOTE

No external mixing capabilities are available with an 8560A/E Option 002.
Resolution bandwidths less than or equal to 100 Hz are not available with
external mixers.

CONFIG,

EXT MXR PRE UNPR

selects either preselected external mixing mode or unpreselected
external mixing mode. This softkey sets the external mixer
configuration used by the softkey menu found under the

EXTERNAL MIXER

softkey under

AUX CTRL

.

If the preselected external mixer mode is selected, rear-panel output
J8 of the analyzer is automatically switched to provide an output of
1.5 V/GHz of the LO frequency, when 0.5V/GHz (FAV) is selected.
The 1.5 V/GHz of the LO frequency definition is required for the
11974 Series preselected external mixers.

EXTERNAL MIXER

accesses a menu of functions that allow you to extend the frequency
range using external mixers. These functions are described below.

FULL BAND

allows you to select a commonly-used frequency band above 18 GHz.
These bands are shown in

on page 77. Use the step keys or

the knob to select a desired frequency band; the selected band
appears in the active function block. Activating

FULL BAND

also

activates the harmonic-lock function.

AMPTD CORRECT

displays a menu of functions that set conversion losses and flatness
data.

AVERAGE CNV LOSS

displays the mean conversion loss for the current harmonic and
allows you to enter new conversion loss data. In a full frequency band
(such as A band), the mean conversion loss is defined as the
minimum loss plus the maximum loss for that band divided by two.
To change the maximum and minimum values, use the

CNV LOSS VS FREQ

softkey. Any change to the average conversion

loss also affects the flatness data, which is described below.

The default conversion loss value for each band is 30 dB.
