These specifications apply to both EMI receivers (Agilent
8542E and 8546A) and both receiver RF sections (Agilent
85422E and 85462A) except where noted.

Specifications

All specifications apply over 0 °C to +55 °C. The EMI receiver
will meet its specifications after 2 hours of storage at a con­stant temperature, within the operating temperature range, 30
minutes after the analyzer is turned on, and after CAL ALL has
been run.
