MILLIMETER WAVE VECTOR NETWORK ANALYZER
37000 Family
33 to 140 GHz
The 37000 family millimeter wave vector network analyzer (VNA) ex-
tends the exceptional performance of the Lightning VNA family to
140 GHz. This improvement to our original millimeter wave system,
based on the 360B VNA, continues our commitment to providing the
highest quality microwave and millimeter wave test equipment avail-
able while still maintaining an intuitive user interface. The minimum
configuration for the millimeter wave VNA has a 37147C VNA, a
3735B Test Set, two synthesized sources, and a pair of millimeter
heads.
Features
•
Measurement speed and accuracy
The millimeter wave VNA, based on our popular Lightning 37000
platform, offers the fastest measurement speed available in a mil-
limeter wave VNA. Measurement speed of approximately 20 ms per
point for an 801 data point sweep means faster tuning and through-
put for your millimeter wave devices. The millimeter wave system
also offers full auto-reversing, 12-term, error-corrected S-parameter
measurements that enable advanced calibration techniques such as
Line-Reflect-Line (LRL), Line-Reflect-Match (LRM), and Thru-
Reflect-Match (TRM) to be used for maximum accuracy in your on-
wafer measurements. For waveguide measurements, the millimeter
wave system supports all of the above methods as well as the off-
set short calibration technique. The 8.5 inch, color liquid crystal
display (LCD) allows users to easily view the data traces for all four
S-parameters while simultaneously displaying limit lines and trace
memory functions. The built-in 3.5 inch MS-DOS
®
compatible floppy
disk drive and internal hard disk drive simplify the procedure to both
store and recall calibrations, front panel setups, and measurement
data. The versatility of the Lightning platform allows data to be gath-
ered using the

The most dynamic range in a millimeter VNA
Increased dynamic range relates directly to increased measurement
accuracy and confidence when measuring millimeter wave compo-
nents and subsystems. To achieve optimum measurement speed
and dynamic range for your measurements, the Lightning millimeter
wave VNA allows the number of measurement averages and video
IF bandwidth to be varied. The Lightning millimeter wave VNA sys-
tem dynamic range is typically 15 dB better than comparable VNAs,
and noise floor specifications are measured with 512 averages not
1024 averages — an important point to consider when making com-
parisons. Simply stated, the Lightning millimeter wave system pro-
vides the best dynamic range with sweep speeds twice as fast as
comparable instruments.
•
Flexible configuration in waveguide and coax
Our flexible module configurations let you specify the capability of
your millimeter wave VNA. We offer two versions of millimeter wave
heads that allow you to tailor the Lightning based millimeter system
to your exact measurement needs. The 3740A series transmission/
reflection modules have simultaneous transmission and reflection
capability, while the 3741A series transmission only module is used
when reflection measurements are not required. A pair of 3740A
modules allows measurement of all four S-parameters. A 3740A
transmission/reflection module combined with a 3741A Transmis-
sion Only module allows measurement of one-path/two port S-para-
meters (S11 and S21).
A single 3740A transmission/reflection module can be used for S11
reflection measurements. The 3740A series also provides the small-
est footprint and lightest weight of any millimeter wave test head on
the market today. This greatly simplifies your test setup; regardless
of whether you are manually adjusting the head position for wave-
guide measurements or have attached them to a wafer probe station.
In order to maximize the flexibility of your VNA, the system architec-
ture provides for a smooth transition between your waveguide and
coaxial device measurements. Simply add a coaxial test set to your
system and now you have the capabilities to fully characterize your
active and passive coaxial devices up to 40 GHz.

Complete measurement solutions
In addition to the millimeter wave VNA measurement system,
Anritsu offers a full line of power meters and synthesized signal
generators up to 110 GHz. To complete your millimeter wave mea-
surement setup, Anritsu also offers solutions for waveguide, on-
wafer, and even coaxial applications. With our custom design and
manufacturing capabilities, we have developed 110 GHz coaxial con-
nectors, couplers, adapters, and even test fixtures for use in your mil-
limeter wave test set-ups.
