Note
U, V, and W-band power sensors are not available from
Hewlett-Packard. For these frequencies use the Anritsu ML83A
Power Meter with the MP715-004 (40 to 60
GHz),
the MP716A
(50 to 75
GHz),
or the MP81B (75 to 110 GHz) power sensors. Since
the Anritsu model ML83A Power Meter is not capable of internally
storing power sensor cal factors, you must manually correct the
data entry. Refer to example 2 for information on manual entry of
correction data.
