Wireless Test System WTS-80

Testing a wireless device on your own bench

We offer a small benchtop test system which we use in our labs for measuring the development and optimizing purposes of spurious emissions and RF antenna performance. A shielded environment is required for these tests.

  • The main competitive advantage of our WTS-80 is about the six patented circular broadband antennas (patent pending) which cover all six main directions of radiation without the need for moving the device while testing.
  • This is useful for a large number of tests with a frequency range between 600 MHz and 12 GHz.
  • The shielded box is small enough to pass through every standard office door (80 cm), is equipped with a DUT support, and a filtered 230 V power supply.
  • The whole system is made in Germany and we can also provide tailored switching units e. g. for using with a high pass filter for measuring harmonica of GSM devices and standard or special customer specific software.

Main Applications

  • Measuring unwanted spurious emissions of all kinds of wireless devices. See example.
  • Gathering wanted radiation and calculating total radiated power (TRP). Based on this, you can determine antenna efficiencies.
  • TRS or sensitivity measurements on all channels.
