Wide frequency band
covers 3G, Wireless LAN and GPS

Comprehensive feature set in single-button
measurement

With its clear and easy operation, the 9102 and 9103

Handheld Spectrum Analyzers present all measurement func-

tions required to quickly and precisely resolve measurement

tasks. The user-friendly interface with intuitive softkeys

enhances operational efficiency.

Frequencies are increasing …
needn't break the budget

The wide frequency range from 100 kHz to 4 GHz (standard

delivery) enables testing of RF systems and modules such as

modern wireless local oscillators.

This frequency coverage also captures the higher harmonics

from amplifier or oscillator modules, plus any spurious signals

that can mix and break through into the pass-band. With the

complete coverage of carrier, IF stages and audio frequencies,

Convenience

No time is wasted in setting up the instrument or hand-copy-

ing settings from one instrument to the other. The 9100 Data

Exchange Software, which comes with the 9100 series instru-

ments, supports enhanced manage and transfer functions.

Channel systems, limit templates, settings and correction

tables can be easily set up and maintained on a PC. Building

new limit templates and correcting tables is child’s play, using

the PC’s mouse.

A live trace can be continuously downloaded from the instru-

ment using optional software. An easy export to standard gra-

phic formats such as BMP and JPG supports the need for quick

documentation of measurement data. Likewise, stored traces

can be uploaded to set the unit to the previous measurement

settings.

the 9102 and 9103 provide the performance needed.

The frequency range of the 9103 Spectrum Analyzer also

covers the frequency range between 5 and 6 GHz. This band

serves new broadband wireless access technologies such as

WiMAX and Wireless LAN; commercial and military radio

services in the C band are located here as well. The 7.5 GHz

frequency range is also available in the 9102 equipped with

the optional 9151 Frequency Extension 7.5 GHz

Manual or automatic control made simple

Controlling the 9102 or 9103 with a PC is easy and convenient

via built-in RS-232 interface or Ethernet port. All functions

of the spectrum analyzer can be controlled via the industrial

standard remote control SCPI command set.

Easy-to-read screen facilitates signal tracing

The high-resolution colour VGA display (640 x 480 pixels) is
excellent for finding misleading spurs or aligning modulators.
Multiple colours facilitate the comparison of measurement
traces on the screen. The extra bright 6.5" TFT display has a
superb 140° viewing angle and thanks to its high luminous
intensity, is ideally suited for outdoor applications. 501 meas­uring points in a trace allow the comprehensive evaluation of
a complex frequency spectrum at a glance.

Markers assist in precise reading of signals

Six markers allow for exact reading of complex signals. The
transmitter performance can be checked, spurious signals can
be detected and sideband levels can be established, using the
markers with their flexibility and clear on-screen display. By
pressing Delta Marker, second and third harmonic levels can
easily be checked. Power level and frequency are displayed in
relation to a reference point.

Pass/fail verdict with limit templates

ACPR enables measurements of the leakage power from a
modulated communication channel into an adjacent channel.

The occupied bandwidth measurement represents the part of
the transmitted power that lies in a specified bandwidth.

This measurement function can supply useful qualitative infor­mation about the used bandwidth, e.g. give useful insight into
transmitter operation.

This single-button function allows rapid measurement deliver­ing information on the characteristics of the specified com­munication channel. All significant values are displayed at a
glance.

Additionally, channel power measurement, ACPR and OBW are
implemented into the spectrum analysis mode. In contrast to
the single-button operation, a user can set measuring range,
resolution and sweep time freely according to individual
needs. In this way, measurements can easily be set up when
predefined communication systems cannot be used.

Limit templates simplify assessment of complex displayed
signals and allow users to decide whether the signal passes
or fails. These templates can contain up to 30 segments.
Simultaneously, it can be established if the signal exceeds an
upper and/or lower limit or not.

High-precision frequency measurement

The integrated frequency counter expands the range of appli­cations to high-precision frequency measurements, required
for many tasks, such as mobile phone repair. These can now
be performed with the 9102 and 9103. For high-precision fre­quency measurements, users no longer need to utilize expen­sive spectrum analyzers or additional frequency counters.
The precision can be increased even further by connecting an
external frequency reference.

Meets future requirements

With the Multi Port, the 9102 and the 9103 are designed to
meet future requirements. The analyzers automatically detect
external options designed for this highly flexible spectrum
analyzer, provide access to special measurement functions and
apply the corresponding correction values.

Checking the exact frequency with the built-in frequency counter

Accurate measurements
in different RF environments

7.5 GHz – standard in the 9103, optional in the
9102

When performing amplitude measurements with a spectrum
analyzer, it is necessary to correct any effects that alter the
signal of interest between the device under test (DUT) and the
analyzer. External devices such as cables, amplifiers, antennas
and additional attenuators can influence the signal level. In
the instrument software, built-in amplitude correction is real­ized. The external device compensation function takes a list
of frequency and amplitude pairs.

Connected linearly, these points offset the input signal accord­ingly. It is easy to set up this correction table using the 9100
Data Exchange Software.

Easy adjustment to different
impedance situations

While an impedance of 50 Ω is most common in most RF
environments, cable TV systems apply 75 Ω. The 9102 and
9103 support this standard as well. When switching between
impedances, the corresponding correction table will automati­cally be loaded to ensure correct measurements. An optional
matching pad is available to correctly terminate the cable.

While the 9102 can be optionally equipped with 7.5 GHz
frequency extension, 7.5 GHz is standard with the 9103. This
frequency range is used by new broadband wireless standards
like C band uplink and downlink for satellite services. All spec­trum analyzer measurement functions, such as Channel Power,
OBW and EMF are also available in the extended frequency
range.

Existing 9102 instruments can be upgraded to the extended
frequency range!

The 9102 can be fitted with the 9151 Frequency Extension

7.5 GHz or the tracking generator option. The 9103 Handheld
Spectrum Analyzer allows measurements up to 7.5 GHz and
can also hold an additional tracking generator.

AM and FM demodulation

The presence of audio signals can be checked by demodulation
of AM or FM signals using Zero Span mode or demodulation
at the marker position and listening via the built-in loud­speaker.

Digital signal processing with
reloadable digital IF

RF signals are digitally processed by microprocessor and
field-programmable gate arrays (FPGA) to ensure both superb
accuracy and repeatability as well as flexibility for future
requirements.

Small and portable

With its minimal footprint, the 9100 series is suitable for
usage both on the bench and in the field. The low weight
makes it a highly portable instrument in the lab and supports
mobile applications in the field that seemed impossible before.
The Willtek 1500 Battery Charger can recharge additional
battery modules outside the 9100. The batteries are easy to
exchange, preparing the instrument for many additional hours
of independent operation in the field.

Typical measurements tasks: cut-off frequencies in the pass-band ...

... and isolation between receive and transmit stages

9132 RMS Detector Option

9162 Insertion Power Sensor

The 9132 RMS Detector helps to analyze digitally modulated
signals better. It adds high precision to the channel power
measurements of the 9102 and 9103. Broadband and narrow­band signals can be measured alike with great accuracy, as the
new detector is capable of analyzing signals that are similar to
noise on the spectrum display. Such signals are smoothed and
displayed with the precise RMS level.

Tracking Option

The tracking generator with its output frequency range
from 1 MHz to 4 GHz expands the application range of the
9102 and 9103 Handheld Spectrum Analyzers into areas like
Distance-to-Fault (DTF) and reflection measurements (VSWR).
The level of the tracking generator is adjust-able from –10 to
–30 dBm which allows adaptation of the output signal to the
demands of passive and active devices under test. (Note: The
Tracking Generator is not available for the 9102 with the 9151
Frequency Extension 7.5 GHz installed.)

Whenever high power levels up to 50 W have to be measured,
the 9102 or 9103 with the 9162 Insertion Power Sensor is the
right solution. A wide frequency range allows to analyze criti­cal applications like the output power of base stations, radios
and other transmitters that can now be monitored easily. The
Power Sensor menu shows the forward and reverse power in
one view. Measurements are optimised for CW, GSM, UMTS,
CDMA and DVB-T signals.

9168 GPS Receiver Option

The 9168 GPS Receiver Option allows to obtain precise meas­urements together with current GPS-derived coordinates. It
is simple and requires only one command to link positional
coordinates with the measurements of the 9102 and 9103
Handheld Spectrum Analyzers. The option utilises the Multi
Port and the RS-232 interface of the instrument. The current
position, speed and altitude can be displayed on the screen in
different formats. The 9168 GPS Receiver Option also makes
it easy to prove the location where a measurement trace has
been taken, which can be important when performing reflec­tion or EMF measurements in the field.

9130 VSWR/DTF Reflection Measurement Option,
9160 VSWR/DTF Bridge

The 9130 VSWR/DTF Reflection Measurement Option, in con­junction with the 9160 VSWR/DTF Bridge, turns the 9102 or
9103 into a full-featured reflection test set.

Today's complex antenna installations include tower mounted
amplifiers, cross polarised antennas and long cable feeds.
Measuring the antenna impedance match is the state-of-the­art method to analyze the antenna system performance.

Using Limit Lines, the antenna system can be approved with one view focusing on the return loss in the uplink and downlink.

6

With the 9102 or 9103 and the 9130 VSWR/DTF Reflection
Measurement Option, measurement technicians are ready for
all the test challenges involved.

All relevant functional parameters are available on a glance
with the reflection measurement mode. With the limit line
capability results can easily be compared with the limits speci­fied by the network operator.

Depending on user preference, the device displays the meas­ured value either as a return loss or in other custom units such
as standing wave ratio (VSWR), reflection coefficient (rho) or
reflected power ratio.

Vector analysis for accurate reflection measure­ments

Modern antenna systems for professional applications are
characterised by a low reflection and a good match. The high
performance is validated for field acceptance and maintenance
using precise instruments. The 9130 VSWR/DTF Reflection
Measurement Option provides high precision because it per­forms vector measurements on the reflected wave. This type
of measurement offers advanced accuracy and highly reliable
results even at low reflected signal levels beyond –20 dB of
return loss.

reeled or already installed, this does not apply. The one port
cable loss measurement mode helps to test from one end of
the cable while the other end is either shorted or left open.
After defining the applicable frequency range for the measure­ment, the average attenuation can be read from the result
field, while the screen shows the frequency response of the
cable.

9160 VSWR/DTF Bridge - just plug and go!

A measurement bridge is the necessary tool for reflection
measurements. Willtek offers a measurement bridge tailor
made for the 9102 and 9103 Handheld Spectrum Analyzers:
The 9160 VSWR/DTF Bridge covers the frequency range up to
4 GHz and fits perfectly to the RF connectors of the 9102 and

9103. High directivity is the basis for the precision achieved in
the return loss measurement. The 9102 and 9103 both provide
supply voltage through the Multi Port. Just plug in the bridge
and it is ready for a full set of new features!

DTF measurements for cable performance testing

Antenna installations are never complete without distance­to-fault (DTF) measurements. The 9130 VSWR/DTF Reflection
Measurement Option provides this type of test, based on FDR
(Frequency Domain Reflectometry) technology. This system
option supports a detailed analysis of the antenna feeder
cable with a total length of up to 1000 m (3280 ft). Worn-out
connectors, cable kinks, water ingress or other cable related
problems can be easily detected and located. The high meas­urement resolution of 501 points ensures quick and efficient
troubleshooting by detecting even small reflections; these
result in a displayed distance to fault.

Prepared for all cable types

Willtek provides predefined cable parameter files for most
known coaxial cables used for installations. They can easily be
uploaded to the 9100; the parameters for rare cable types can
be determined with the instrument. The user decides whether
he wants to set the measurement range manually or automati­cally.

One-port cable loss measurement

Measuring cable loss is easy only as long as both ends of a
cable are accessible. However, for cables which are either

Radiation Measurements
with the 9131 EMF Measurement Option

Radiation from base stations and broadcast stations can be

measured easily with the 9102 or 9103 and the 9131 EMF

Measurement Option. The 9100 takes measurements of the

electromagnetic field over a user-definable frequency range and

displays the field strength (in V/m) or the power flux density (ni

W/m²).

The option also allows selecting one of two additional filters (9

and 120 kHz resolution bandwidth) which are typically used for

radiation measurements.

Radiation emission …

With these measurements, operators of cellular networks and

broadcast stations fulfil a requirement from the regulator; many

countries stipulate a proof that the radiation of the installed

transmitter is within specified limits. A directional antenna helps

to measure the emitted radiation. Willtek offers two antennas

accommodating different frequency ranges: the 9172 Directional

Antenna, 80 to 1000 MHz and the 9173 Directional Antenna,

300 to 3000 MHz.

Only the 9102 or 9103 Handheld Spectrum Analyzer equipped

with the 9131 EMF Measurement Option and the directional

antenna is required to perform emission measurements in

accordance to the ICNIRP standard. The combination provides

a handheld solution that is easy to carry, easy to read even

at daylight, and easy to convert into a system for other test

requirements such as antenna system measurements.

The Directional Antenna is the perfect fit for emission measurements

Immission measurements are easy to perform with the Isotropic
Antenna

… and immission

Engineering offices and regulatory bodies are interested in

the radiation exposure in a particular place. The 9102 or 9103

with the 9131 EMF Measurement Option and an appropriate

antenna measures electromagnetic waves omni-directionally.

The overall field strength of the desired frequency range is

displayed. The lightweight, hand-portable spectrum analyzer

eases measurements in the field, and the user enjoys the clear

reading from the bright display.

Cyclic measurements of the interference are possible with the

integrated support for remote control. Two interfaces – an

RS-232 and a LAN connector – offer choices for controlling

the instruments over a modem or a local network.

Willtek offers two antennas for immission measurements: the

9170 Biconical Antenna and the 9171 Isotropic Antenna. Both

support measurements in all directions, but use different ways

to accomplish the goal.

By manually turning the dipole antenna element of the 9170

Biconical Antenna, the same antenna pair can be used to

take measurements in different directions. This helps to keep

variations in the results to a minimum. The 9102 and 9103

Handheld Spectrum Analyzers support consecutive measure-

ments in three axes and calculates the resulting field strength.

The 9171 Isotropic Antenna includes six antenna elements. The

9102 or 9103 measures the signal from each pair of antenna

elements consecutively; it switches the elements via the Multi

Port of the 9102 or 9103. The analyzer detects the antenna

type automatically and loads a set of specific calibration val-

ues from the antenna into the 9102 or 9103, which provides

even higher accuracy of the measurement results.
