Always use the information printed on the SAX label of your module.

•
When using your signal analyzer with the SAX, you must set the analyzer to external mixing, including
harmonic and Doubler Switched parameters.
For the N90x0A Models:
[Input/Output] > External Mixer > External Mixer > Ext Mix Setup > Edit Harmonic Table >
[Enter] (or select OK).
Table Type > Doubler Switching > Harmonic > [N] > Enter N value (see SAX label on module, or see VDI
document, for N value)
For the N90x0B Models:
[Input/Output] > Select Input > External Mixer > External Mixer Setup > Table Type > Doubler Switching
> Harmonic (under Harmonic Table) > Enter N value (see SAX label on module, or see VDI document, for
N value)
For improved spurious response:
•
Change the number of sweep points:
[Sweep/Control] > Points > [40001]
Multi-Touch Sweep > Sweep Config > Points > [40001]
•
Reduce resolution bandwidth:
[BW] > Res BW > [300 kHz]
•
Turn on Signal ID:
[Input/Output] > External Mixer > Signal ID > On > Signal ID Mode > Image Suppress
Multi-Touch Input > Output > Signal ID > On > Signal ID Mode > Image Suppress
There is data on the USB drive that can be used to create a corrections file to improve amplitude
accuracy.

When using the LO/IF (L) Input (External Mixing), use LO (L): N= X, with
"X" being the multiplication factor value shown on your SAX label.
When using the LO/IF (H) Input, use LO (H): N= X, with "X" being the
multiplication factor value shown on your SAX label.
SAX Label
On the SAX label, the multiplication
factor values are circled. This is an
example only; the actual values will
vary.
