Description and Operating Characteristics

Description and Operating Characteristics

The HP 8511A four channel frequency conve rter test set, has been designed
to operate with the HP 8510 network analyzer a nd other microwave
accessories (like c ouplers and power splitters). The HP 8511A provides a
conv enient means of customizing a test configuration for a variety of
applications within the frequency range of 45 MHz to 26.5 GHz. In addition
to configurations for measuring reflection and transmission parameters of
one-port or two-port devices, youcan build configurations to characterize
antenna parameters, radar c ross sections and fr equenc y translation devices.
Figure 1-2 on page 1-5 shows one possible measurement set-up.
