Frequency Extender Procedure
General Comment on Frequency Converter Usage:
OML heads are limited to 6 GHz span.
Example:
If you are using a 24–40 GHz OML head you can sweep:
— 24–30 GHz and 25–31 GHz, but not:
— 24–31 GHz
But, in OTA mode, because each frequency is set separately, you can set CC0
to 24 GHz and CC1 to 31 GHz.
But, you cannot set CC0 to 4 GHz and CC1 to 32 GHz. You have to stay within
the band of the OML mixer (24-40 in this example), if you are enabling an
external head.

input (100 MHz). Default is OFF (maximum span – 6 GHz).
Setup Corr Auto Edit SA
corrections for a frequency converter head are automatically loaded
("...Default.csv"). These corrections are defaults for the specific head,
to improve nominal accuracy of the amplitude readings, but this accuracy
is not specified. Press Edit SA, when you want to view or edit the
corrections using the SA mode corrections. This state stops all
auto-loading of the default corrections. Refer to step 8.
The other non-SA supported modes do not allow viewing or editing of the
corrections, but they all share the same corrections.
Therefore, any manual changes to the corrections (using SA via Edit SA)
are then used by other supported modes (RTSA/IQA/OTA) as well.
