HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

HP 85106D mm-Wave System 1-1
1 Getting Started
Introduction The HP 85106D mm-wave S-parameter network analyzer is a banded
waveguide system. Table 1-1 lists the waveguide bands available from
33 GHz to 110 GHz. You must add two HP 85104A series test set modules
for each waveguide band. For fully error-corrected measurements, it is
necessary to use a calibration kit in the same frequency band as the test set
modules being used. Refer to “Frequency Bands and Accessories Available”
on page 1-4 in this manual for the specific model numbers required for your
system.
The HP 85106D mm-wave system arrives with one each of the following
installed in a system cabinet:
•HP 8510C Network Analyzer
•HP 85105A mm-Wave Controller
•HP 83621B Synthesized Source (quantity of two)
•System Cabinet - 1600 mm Rack, all instruments noted above are
mounted in this cabinet.
•An HP 85106D system configuration disk is included with your system.
This disk allows you to load the mm-wave instrument and hardware
states into your system. Refer to Chapter 2, “Operation” for more
information about loading your system’s configuration.
NOTE To complete your mm-wave system, two test set modules must be ordered
for the frequency band of interest. Refer to “Frequency Bands and
Accessories Available” on page 1-4 in this manual.
