dynamic range and resolution. The exclusive phasor impulse mode
will show you the true impedance characteristics of mismatches in
waveguide, microstrip, and other band-limited media.
•
Multiple source control
Conveniently test mixers and multipliers through the 37100C/
37200C/37300C's multiple source control. Separately control the fre-
quency of two sources and a receiver without the need for an exter-
nal controller. Independently specify the sweep ranges and output
powers of the sources and the sweep range of the receiver to ac-
commodate testing of frequency translation devices.

LabVIEW
®
compatibility
Standard with every 37100C/37200C/37300C series analyzer is
National Instruments LabVIEW
®
instrument driver. Create custom
test programs (virtual instruments) in less time with LabVIEW
®
's
graphical programming environment. Take advantage of the network
analyzer's high data throughput for tuning operations. Fast data
transfers over GPIB permit near realtime updates on your PC's display.
Customize programs to automatically display, test, and document
measurement results. Reuse virtual instruments in other test routines to
minimize program development time. LabVIEW
®
gives you full ac-
cess to more than 900 mnemonics in the 37100C/37200C/37300C
analyzer's command set for complete automated data collection and
analysis.
•
Internally controlled AutoCal
®
One source of potential errors and inaccuracies in any network ana-
lyzer system is the calibration of that system. The Anritsu AutoCal
automatic calibrator is designed to speed and simplify the calibration
of your 37200C/37300C VNA. Using the built-in software support
and an AutoCal module connected to the serial port on the rear panel
of the instrument, you are ready to make fast, accurate, and repeat-
able calibrations.
•
Three-year factory warranty
All 37100C/37200C/37300C series VNAs are backed with a no-
questions-asked three-year warranty.
•
Upgradeability
The 37100C/37200C/37300C series analyzers are designed to ac-
commodate higher frequency ranges and more powerful features as
your requirements grow. Any 37100C/37200C/37300C series VNA
can be upgraded to any other model in the instrument family, or any
other series, to fit your changing requirements. Contact Anritsu
Customer Service to request an upgrade and an Anritsu service en-
gineer will install the added capability and verify your system's total
performance. Upgradeability is a cost-effective approach to satisfying
today's production needs while providing the flexibility to meet tomor-
row's demands. System software upgrades are as easy as inserting
new discs into the instrument's floppy drive.
Applications
•
Filters
Let the analyzer's wide dynamic range show you filter rejection and
input match on the same display. Overlay traces and tune for opti-
mum transmission and group delay responses without reduction in
sweep speed.
Further speed improvements are possible using the instrument's
tune mode. This unique feature helps users optimize sweep times in
one direction for better hand-to-eye tuning while maintaining a 12-
term corrected S-parameter display. Anritsu's tune mode maximizes
sweep speed and accuracy, simultaneously, by allowing you to
choose when reverse parameters are updated.
Automatically locate filter center frequency, 3 dB bandwidth,
max/min insertion loss, 0 dB points, Q, and shape factor. Instantly
measure passband phase distortions with Anritsu's automatic refer-
ence plane extension capability. A single key press quickly identifies
filter non-linear responses.

Amplifiers (available on 37300C series only)
Easily measure amplifier gain compression vs. input power or fre-
quency. Power meter assisted flat output power calibration provides
capability to measure power in dBm. A 1 watt, 70 dB (60 dB on >40 GHz
models) step attenuator in the port 1 path, and a 40 dB step attenu-
ator in the port 2 path, coupled with 20 dB ALC range, give complete
control to characterize virtually any amplifier. This range is reduced
to 12 dB at frequencies >50 GHz. Internal bias tees simplify DC bi-
asing of your active designs. A front panel loop allows external am-
plifier insertion, increasing port 1 power up to 1 watt for high input
power amplifiers.
•
Mixers
Mixers as multiport devices take advantage of the multiple source
control and set-on receiver mode features.
The 37100C/37200C/37300C can be configured to measure the rela-
tive harmonic level of test devices with set-on receiver mode capabil-
ity. The 37100C/37200C/37300C's unique phase locking scheme al-
lows it to operate as a tuned receiver by locking all of its local oscil-
lators to its internal crystal reference oscillator. Set-on receiver
mode capability significantly increases the versatility of the
37100C/37200C/37300C VNA in applications that check for harmonics,
intermodulation products, and signals of known frequency.
Multiple source control capability allows a user to independently con-
trol the frequencies of two sources and the receiver without the need
for an external controller. The frequency ranges and output powers
of the two sources may be specified. A frequency sweep may be
comprised of up to five separate bands, each with independent
source and receiver settings, for convenient testing of frequency
translation devices such as mixers. Up to five sub-bands may be
tested in one sweep. This feature enables users to easily test mixers,
up/down converters, multipliers, and other frequency conversion de-
vices.
•
Microstrip devices
The 37200C/37300C series offers complete substrate measurement
solutions for both microstrip and coplanar waveguide (CPW) de-
signs. The 37200C/37300C series analyzers accommodate the mod-
el 3680 series Universal Test Fixtures (UTF), calibration kits, and ver-
ification kits. Guaranteed system specifications provide assurance
that your test results are accurate and verifiable.
Completely characterize connectorless devices with the 37200C/
37300C's Line-Reflect-Line (LRL) and Line-Reflect-Match (LRM)
calibration capability. The four channel design provides true LRL/
LRM error-correction giving you the highest performance available
for in-fixture measurements. Highly reflective devices, along with
well matched ones are measured with the same degree of ease.
Automatic dispersion compensation improves measurement accura-
cy to help you determine phase distortions in all your microstrip de-
signs. The result is quality measurements you can count on for your
connectorless devices.
•
Antennas
Far field measurements are enhanced with the speed of taking data
over GPIB, using the 37100C in fast CW mode. Rates of 0.8 ms/point
can be achieved using internal triggering, 1.2 ms/point with external
triggering, and 1.5 ms/point with GPIB triggering.
For near field measurements, internal buffer data collection is pro-
vided to allow saving active channel measurement data from multi-
ple sweeps without having to synchronize and collect data at the
end of each sweep. The 37100C can store up to 50,000 data point
measurements, each consisting of two real and imaginary IEEE 754
4-byte floating point numbers.
•
Multiport devices
The 37100C offers direct access to all four samplers. Flat test port
power calibration using a power meter allows source calibration and
characterization of all four receiver channels. Ratioed measurements
can then be performed on any combination of the four channels.
Absolute dBm measurements can also be made through the user-
defined parameter feature.
