33 GHz to 110 GHz
The Agilent Technologies 85106D
millimeter-wave network analyzer
system extends the performance of
the 8510C network analyzer to the
millimeter-wave frequencies. This
system can be configured for measurements in the 33 to 50 GHz, 40
to 60 GHz, 50 to 75 GHz, and 75 to
110 GHz waveguide bands.
The 85106D network analyzer system
provides the best performance to
meet your new design and test challenges, with high accuracy, dynamic
range and frequency resolution for
measurements at the millimeter-wave
frequencies. The impressive accuracy
of the 85106D system can be attributed to the “thru, ref lect, line” TRL
calibration standards which are used
to characterize and remove systematic
errors from the measurement. With a
TRL calibration, the residual system
uncertainties can be reduced to 46 to
50 dB directivity and source match.
For millimeter-wave components that
require the measurement of a wide
range of power levels, a specified high
dynamic range of 87 to 75 dB can be
achieved with the 85106D.
Fully integrated for your
convenience
The millimeter-wave network analyzer
system setup is extremely easy, so
you can begin making measurements
immediately. All of the necessary
amplification and switching for millimeter-wave S-parameter measurements are integrated into the Agilent
85105A millimeter-wave test set
controller. The waveguide test set
hardware is integrated into two
85104A series millimeter-wave test
set modules. Each module contains
one-half of a full S-parameter test set,
including the frequency multiplier,
directional couplers, harmonic mixers, and isolators. These test set modules are easily maneuverable on work
surfaces during calibration and
measurement.
Distortion-free measurements in
frequency and time
Option 010 of the 85106D system
adds time-domain capability to the
network analyzer, enabling transformations from frequency domain data
to the time domain. Time domain is
an extremely powerful tool that allows
you to gain further insight into the
behavior of a component or circuit.
In addition to correcting for the nonlinear phase shift versus frequency of
standard rectangular waveguide, the
85106D also corrects for the dispersion
in the time domain. Using the “waveguide delay” function, the time-domain
response can be corrected for any dispersive effects.

Microwave and millimeter-wave
coverage
A combination microwave/millimeterwave S-parameter system can be configured in the same rack by adding a
microwave test set to the 85106D system. No reconnections are required
when switching between millimeter
wave and microwave operation. The
Agilent 85105A millimeter-wave controller is equipped with the IF and RF
switching capability for routing millimeter-wave or microwave test set.
No external switches or switch drivers are necessary. The RF and IF signals are automatically switched to the
appropriate test set and system states
are quickly and easily recalled from
the external disc drive with a few
front panel keystrokes.
Economical upgrade path
It is both economical and convenient
to add other wave-guide bands to
the 85106D. Simply disconnect the
85104A test set modules from the
millimeter-wave controller, and connect the new test set modules. The
appropriate configuration is easily
recalled from the disc drive with a
few front panel keystrokes.
It is also possible to expand an existing 8510B or 8510C microwave network
analyzer system to millimeter-wave to
meet new design or test challenges. A
single 8510 can control multiple test
sets, which means that you can continue to use your microwave test set
along with your millimeter-wave system
with no degradation in performance.
Precision waveguide flanges
improve performance
All millimeter-wave standards and
adapters from Agilent Technologies
utilize the precision waveguide flange
design. This design uses precision
locating pins, a lip around the perimeter of the flange, and tighter tolerances of the alignment pin locations
and pin diameters to minimize the
possible misalignment of the waveguide aperatures.
The millimeter-wave precision waveguide flange makes its greatest contribution by improving flange connection repeatability, which is the biggest
source of error after calibration.
Flange repeatability can be improved
by three orders of magnitude when
compared to the standard waveguide
flange. This repeatability error is
considerably less than the residual
system errors after error correction.
Waveguide calibration and
verification kits
The Agilent 11644A series waveguide
calibration kits provide the standards
necessary to take full advantage of
the built-in accuracy enhancement
capability of the 8510C network analyzer. Each calibration kit contains
two straight waveguide test port sections, a flush short circuit, a precision quarter-wavelength shim, and a
fixed-load or sliding load termination.
In addition to providing the “offset”
for the offset short and offset load
standards, the precision shim in the
11644A series calibration kits is also
used as the “line” standard for a TRL
calibration.
The Agilent 11645A series waveguide
verification kit contains a standard
section, a standard mismatch, and
20 dB and 50 dB attenuators. Each
device in the verification kit is supplied with data and measurement
uncertainties that are traceable to the
National Institute of Standards and
Technology (NIST). As with all Agilent
verification kits, the automated system
verification process compares the
device data with the data that your
system actually measured.
