* The HP 8753D RF source characteristics in this mode are dependent on the stability of the external LO source .
The RF source tracks the LO to maintain a stable IF signal at the R channel receiver input. Degradation in
accuracy is negligible with an HP 8642A/B or HP 8656B RF signal generator as the LO source .
y
Refer to \HP 8753D Descriptions and Options" for a functional description.
z
Operation from 3 GHz to 6 GHz requires option 006.
x
Measurement accuracy is dependent on the stability of the input signal.
