  • Wireless Test Labs

    The Howland Company

    The Howland Company wireless test labs were developed in collaboration with Motorola engineering. The first priority was to design products that would set the industry standard for accurate measurements. With this goal in mind, it became apparent that how one mounts the handset to the positioning system is critical if the measurement uncertainty is to be minimized. The classical approach would have been to mount the handset on a two-axis positioner. However, if this is done, then the positioner structure, even if it is plastic, perturbs the electromagnetic field and dramatically increases the measurement uncertainty and creates ''gravity vector'' problems which contribute additional measurement uncertainty.

  • Combination Wave/Surge Generators

    EM Test

    Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. Another source for surge pulses are switching transients originating from switching disturbances and systems faults.Due to the characteristic of the phenomenon nearly every electrical and electronical device may suffer from such lightning events which justifies the necessity of surge tests being widely performed. Surge voltage can reach several thousands of volts and surge current is seen to reach several thousands of amps.EM TEST offers a wide range of Combination Wave generators with different output voltage ranges for various test requirements:

  • Surge Generator
