MEASUREMENT CONSIDERATIONS FOR NETWORK
ANALYSIS AT MILLIMETER FREQUENCIES
This paper discusses the considerations for making accurate vector network measurements
with the HP8510 in the wa veguide bands between 26.5 G Hz and lOO G Hz. Methods of calibra-
tion, including one not requiring the use of a sliding load, types of calibration standards, flange
repeatability, and other factors affecting system performance will be discussed. Measurement
results for a variety of devices and calibration methods will be shown at frequencies up to 100
GHz.

8510 microwave network analyzer. Since 1980 he has been Project Manager for the HP
8511-8515 test sets for the HP 8510 and is currently involved with the extension of the HP 8510
to millimeter-wave frequencies.

The system that will be described allows most of
the features of the HP 8510 to be used at millimeter-
wave frequencies. Vector error correction and time
Features domain are available. Due to the band-pass nature
of waveguide, only the band-pass mode of time
