9101 Handheld Spectrum Analyzer

Small, Portable Spectrum Analyzer for RF Servicing up to 4 GHz

bestproductWilltek Communications receives prize for outstanding innovation in spectrum analysis > more
Willtek’s 9101 Handheld Spectrum Analyzer is a low cost, full-featured spectrum analyzer. With a frequency range up to 4 GHz, the 9101 can test all modern wireless local oscillators, plus the harmonics and spurs that can mix and break through into the pass-band. Its complete coverage of carrier and IF stages give the performance needed when other analyzers run out of bandwidth.

Maximum Performance, Minimum Package

  • Comprehensive feature set in one-button measurement
  • Easy-to-read screens make all the difference in finding signals
  • Speedy assessment of signal quality with marker and limit template capabilities.
  • Get more out of digitally modulated signals through RMS channel power measurement functions
  • Accurate measurements in different RF environments due to external device compensation and impedance adjustment.
  • Remote control via RS-232 and Ethernet.

The 9101 includes all the specifications of other sophisticated lab instruments, all in a handheld package weighing less than 2.5 kg, including battery -- no heavy instruments to carry, and no more cluttered benches. The 9101 can be run and reloaded from the 12 V cigarette lighter adapter.

No time is wasted in setting up the instrument or copying settings from one instrument to the other by hand. The 91xx Data Exchange software, which comes with the 9101, supports enhanced manage and transfer functions.


9102 Handheld Spectrum Analyzer

Portable Spectrum Analyzer Designed for Scalar Network and Spectrum Analysis

Willtek’s 9102 Handheld Spectrum Analyzer is a multifunction instrument designed for lab and field applications concerning scalar network and spectrum analysis, including cable and antenna measurements and EMC pre-qualification tests. The basic 9102 has a frequency range of 100 kHz to 4 GHz and a resolution bandwidth (RBW) of an exceptional 1 kHz. An optional frequency extension allows measurements up to 7.5 GHz. The 9102 is small in size and weight, with a large, bright display and easy-to-use menu structure.

Options Provide Specific Solutions and Applications
The 9102 offers a vast range of options developed for specific applications. For example, a tracking generator option supporting cable measurements, and a reflection measurement option are available. The flexibility these options provide ensures that the 9102 is an affordable solution, not one that includes unneeded, more expensive features.


  • Optional frequency extension to 7.5 GHz
  • VSWR and DTF measurements supporting antenna installation and verification (option)
  • Tracking generator option enables cable measurements in the field
  • Radiation measurements of base stations and broadcast stations (EMF option)
  • Scalar network analysis (amplifier gain over frequency or filter characteristics) and antenna measurements
  • Prequalification for EMC (electromagnetic compatibility) tests
  • Displayed average noise level at -117 dBm
Dynamic range of 70 dB


3100 Mobile Fault Finder

A Go/NoGo Tester for Simple Testing of 2G/3G Mobile Devices

The 3100 Mobile Fault Finder was designed to meet the requirements of point-of-return and service center functional testing.  It provides a user-friendly and cost-effective way to identify "No Fault Found" devices being returned from the market.  Additionally, the 3100 provides a quick functional verification of mobile devices as they leave the service centre, ensuring proper operation when returned to the customer. The 3100 has no display and is therefore remote controlled from a PC via a simple serial or USB connection. The PC application is very simple to use and provides easy management of mobile characterisation values


  • Supports GSM, GPRS, EDGE, WCDMA, CDMA2000, 1xEV-DO testing
  • Separates faulty and no-fault-found (NFF) mobile phones to maximise revenues
  • Provides complete solution for Go/NoGo testing when used with the 4920 RF Shield Box, 4921 RF Shield and 4916 Antenna Coupler
  • Simple, easy-to-use interface, minimising training time
  • Pre-attenuation values online available
Bluetooth option for Go/NoGo testing available


2303 Stabilock

Regular testing of TETRA phones ensures safe and reliable communication

In critical situations, users in the public safety and security sector fully rely on their communication devices. To help organisations such as police, fire brigades and paramedics provide maximum safety and reliability to their users, Willtek designed the 2303 Stabilock. It is the first TETRA mobile station tester which is specifically made for testing TETRA radios in a service environment. Service managers can now use the affordable instrument to ensure that the radios are fully operational; this is particularly important for the police, fire brigades and paramedics where lives may depend on proper communication tools!

The 2303 Stabilock delivers precise results the fast way. No matter if Trunked Mode or Direct Mode (optional), 400 or 800 MHz band: After setting up network parameters and frequency range the tester is ready for operation. The high contrast 6.5” TFT colour display is split into four sections for clear reading of test results in numeric or graphic format. All settings and commands are accessible via six softkeys or with one-hand operation using the turn-and-push dial. Reducing TETRA complexity to what is really needed in service – with this operational concept, users can operate the instrument easily with a few key presses on the Stabilock’s high-quality click-type keyboard. Alternatively, a standard USB mouse provides access to all screen elements as on a PC.


  • Supports TETRA radio tests relevant for service
  • Intuitive and failsafe user interface
  • Made for the PMR service environment
  • Bright screen and robust case
  • Portable, lightweight and compact
  • Optional battery operation
