CAUTION
NOTE

Operation

Leveling Feedback Loop
Never interrupt the LO leveling feedback from the reference module leveling
coupler, detector, or leveling cables. Doing so can cause the LO power to
exceed the damage level of the HP 11970 mixers.
Electrostatic Discharge
When installing the mixers, connect the SMA cables to the test/reference
modules before connecting them to the mixers. This will minimize the
danger of an electrostatic discharge damaging the mixers.
The HP 85325 millimeter wave system is designed to be used with a
HP 85310A or HP 85301B. Refer to these instrument manuals for system
level operating information.
