IMPORTANT!
Due to limitations in the OML hardware, the heads have a 6 GHz frequency
span.
Examples
Using a 24 to 40 GHz mixer, you can sweep:
— 24 to 30 GHz and 25 to 31 GHz, but not
— 24 to 31 GHz
Assuming the same 24 to 40 GHz mixer, using OTA mode, you can
— Set a CC0 to 24 GHz and CC1 to 31 GHz, but not
—
PAA and 89600 VSA (via the Remote Server feature) is compatible with the
frequency converter heads, but cannot apply or edit the frequency head
corrections.

These settings are used to set up a frequency extender head (e.g., OML head).
The frequency extender feature can be used in OTA FR2 measurements. See

LTE TDD Option 371, 5GTF Option 377 (CPU2 Only)."
The frequency extender heads are an external down converter that extends the
FieldFox's range. The frequency extender head makes use of the FieldFox's
source and uses USB port for power. The FieldFox support for the frequency
extender head includes:
— The frequency extender heads are compatible with to SA, IQA, OTA, PAA,
The OML frequency extenders have approximately 4 to 10 dB of gain
depending on the mixer and frequency.

— The USB ports are used to supply power to the head
— Port 1 is used to supply an LO signal to the head. The LO signal is
automatically generated, using the internal source. Therefore the
application disables normal Port 1 access to the internal source. But,
automatic alignments of the SA Receiver still remain active using an
internal path for the source.
— Port 2 is where the head delivers the downconverted signal to the SA
receiver.
