Theory of Operation
0.045 to 2 GHz Band In the .045 to 2 GHz range, the signal from the RF source is not multiplied; it
is applied directly to the mixers. The mixers for this range are located in the
millimeter wave controller, and are designed to use the fundamental of the
LO input frequency. This applies to 8510XF systems equipped with
Option 005 only.
