Operating and Service Manual
1. Only supplied with R band.
2. This wrench is specially designed. The "closed" end has been
machined to be smaller, and has been slotted so it will fit over a cable.
The modified end has another feature as well, it slips when
approximately 10 inch-pounds of force is exerted on the SMA
connection. 10 inch-pounds is the torque specification for all SMA
connections inside the mm-wave modules, or inside the HP 85309A.

Adjustments

Only the HP 85309A LO/IF unit requires periodic circuitry adjustments.
Refer to the HP 85310A or HP 85301B Operating and Service Manual for
HP 85309A adjustment procedures. If the LO and RF source's timebases are
not connected together, refer to either of the manuals (mentioned above) for
adjustment instructions.
The LO power to the test and reference modules must be adjusted during
installation. Refer to Installation, Chapter 1 for more instructions.
