General Information
Description and Operating Characteristics
Description and Operating Characteristics
The HP 8511A four channel frequency converter test set, has been designed
to operate with the HP 8510 network analyzer and other microwave
accessories (like couplers and power splitters). The HP 8511A provides a
convenient 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, you can build configurations to characterize
antenna parameters, radar cross sections and frequency translation devices.
Figure 1-2 on page 1-5 shows one possible measurement set-up.
