Introduction
High Performance Handheld S-Parameters
Anritsu introduces the MS202x/3xC VNA Master + Spectrum Analyzer, the industry’s broadest frequency handheld solution
to address cable, antenna, component, and signal analysis needs in the field: with frequency coverage from 5 kHz up to
20 GHz. Equally impressive, this broadband measurement tool offers the industry’s first 12-term error correction algorithm in
a truly handheld, battery-operated, rugged multi-function instrument. And now the MS203xC models include a powerful
spectrum analyzer which multiplies user convenience by combining spectrum analysis with the VNA into a single
measurement powerhouse for the harsh RF and physical environments of field test. Whether it is for spectrum monitoring,
broadcast proofing, interference analysis, RF and microwave measurements, regulatory compliance, or 3G/4G and wireless
data network measurements, this VNA/Spectrum Analyzer combination is the ideal instrument for making fast and reliable
measurements in the field.

Data Points2 to 4001 (arbitrary setting); data points can be reduced without recalibration.
The reference planes of a calibration (or other normalization) can be changed by entering a line length. Assumes no loss, flat magnitude, linear phase, and
constant impedance.
Instead of manually entering a line length, this feature automatically adjusts phase shift from the current calibration (or other normalization) to compensate for
external cables (or test fixtures). Assumes no loss, flat magnitude, linear phase, and constant impedance.
Frequency RangeFrequency range of the measurement can be narrowed within the calibration range without recalibration.
Group Delay Aperture
Defined as the frequency span over which the phase change is computed at a given frequency point. The aperture can be changed without recalibration. The
minimum aperture is the frequency range divided by the number of points in calibration and can be increased to 20% of the frequency range.

Round-trip cable loss measurements are convenient for field personnel testing installed cable or waveguide runs. This one-port
technique provides one-way data after twice traversing the cable. The following two sets of uncertainty curves, less than 6 GHz
on the left and greater than 6 GHz on the right, present worst-case uncertainty by DUT Match (i.e., Log Mag) when using
VNA Master for one-port cable loss measurements. As a practical tip, consider using a two-port transmission measurement
technique to improve upon these one-port cable loss uncertainties.

Measurement Options Specifications
Time Domain (Option 0002) (includes Distance Domain Option 0501)
The VNA Master can also display the S-parameter measurements in the time or distance domain using lowpass or bandpass
processing analysis modes. The broadband frequency coverage coupled with 4001 data points means you can measure
discontinuities both near and far with unprecedented clarity for a handheld tool. With this option, you can simultaneously view
S-parameters in frequency, time, and distance domain to quickly identify faults in the field. Advanced features available with
this option include step response, phasor impulse, gating, and frequency gated in time. The option includes computational
routines that further enhance the Distance Domain results by compensating for cable loss, relative velocity of propagation,
and dispersion compensation in waveguide.

WindowingRectangular, Nominal Side Lobe (NSL), Low Side Lobe (LSL), and Minimum Side Lobe (MSL)
Distance Domain (Option 0501) (not required if Option 0002 is purchased)
Distance Domain Analysis is a powerful field test tool to analyze cables for faults, including minor discontinuities that may
occur due to a loose connection, corrosion, or other aging effects. By using Frequency Domain Reflectometry (FDR), the
VNA Master exploits a user-specified band of full power operational frequencies (instead of DC pulses from TDR approaches)
to more precisely identify cable discontinuities. The VNA Master converts S-parameters from frequency domain into distance
domain on the horizontal display axis, using a mathematical computation called Inverse Fourier Transform. Connect a
reflection at the opposite end of the cable and the discontinuities appear versus distance to reveal any potential maintenance
issues. When access to both ends of the cable is convenient, a similar distance domain analysis is available on transmission
measurements.
Option 0501 Distance Domain will improve your productivity with displays of the cable in terms of discontinuities versus
distance. This readout can then be compared against previous measurements (from stored data) to determine whether any
degradations have occurred since installation (or the last maintenance activity). More importantly, you will know precisely
where to go to fix the problem and so minimize or prevent downtime of the system.
Power Monitor (Option 0005) (MS202xC models only) (requires external detector)
Transmitter measurements in the field are possible when
using this VNA Master software mode with a separately
purchased Anritsu 560 series detector. A variety of detectors
are available to 50 GHz, but the popular 560-7N50B covers
10 MHz to 20 GHz with a measurement range of –50 to
+20 dBm with better than 0.5 dB flatness to 18 GHz. After
zeroing the detector to ensure accuracy at low power levels,
the software offers intuitive operation for absolute and
relative readouts in dBm or Watts.
Display Range–80 dBm to +80 dBm (10 pW to 100 kW)
Measurement Range–50 dBm to +20 dBm (10 nW to 40 mW)
Offset Range0 dB to +60 dB
Resolution0.1 dB, 0.1 xW (x = n, µ, m based on detector power)
Accuracy
± 1 dB maximum for >–40 dBm using
560-7N50B detector
For highly secure data handling requirements, this software option prevents the storing of measurement setup or data
information onto any internal file storage location. Instead, setup and measurement information is stored ONLY to the
external USB memory location. A simple factory preset prepares the VNA Master for transportation while the USB memory
remains behind in the secure environment. The VNA Master cannot be switched between secure and non-secure operation by
the user once configured for secure data operation. As an additional security measure, with this option enabled, the user can
choose to blank the frequency values displayed on the screen.
12
Bias Tee (Option 0010)
For tower mounted amplifier tests, the MS20x/3xC series
with optional internal bias tees can supply both DC and
RF signals on the center conductor of the cable during
measurements. For frequency sweeps in excess of 2 MHz,
the VNA Master can supply internal voltage control from
+12 to +32 V in 0.1 V steps up to 450 mA. To extend
battery life, an external power supply can substitute for the
internal supply by using the external bias inputs instead.
Both test ports can be configured to supply voltage via this
integrated bias tees option. Bias can be directed to VNA
Port 1 or Port 2.

Port 2
Vector Voltmeter (Option 0015)
A phased array system relies on phase matched cables for
nominal performance. For this class of application, the VNA
Master offers this special software mode to simplify phase
matching cables at a single frequency. The similarity between
the popular vector voltmeter and this software mode ensures
minimal training is required to phase match cables. Operation
is as simple as configuring the display for absolute or relative
measurements. The easy-to-read large fonts show either
reflection or transmission measurements using impedance,
magnitude, or VSWR readouts. For instrument landing system
(ILS) or VHF Omni-directional Range (VOR) applications,
a table view improves operator efficiency when phase
matching up to twelve cables. The MS202x/3xC solution
is superior because the signal source is included internally,
precluding the need for an external signal generator.

GPS (Option 0031) requires external GPS antenna
Built-in GPS provides location information (latitude, longitude, altitude) and Universal Time (UT) information for storage
along with trace data so you can later verify that measurements were taken at the right location. The GPS option requires a
separately ordered magnet mount GPS antenna (2000-1528-R or 2000-1652-R), which are configured to mount outside on
a metallic surface. Frequency accuracy is enhanced for the Spectrum Analyzer (on MS203xC models) when Options 0025
Interference Analyzer and 0027 Channel Scanner are engaged and the enhanced accuracy is maintained for up to 3 days after
loss of GPS lock.
