2 Recommended Test Setup

To fully verify a setting, extensive testing is required.

A mimimum to run all the measurements suggested in this document is:

  • Signal generator that is able to send packets
  • Spectrum analyzator
  • Software that is able to control the instruments for automated measurements. This may be Labview or Matlab.

All testing should be done conducted. Strong unwanted transmitters could impact the results and use of a shielded test setup should be considered if a base station or similar impacts the results.

A VNA or similar should be used to measure the cable loss if exact results are needed. For sensitivity measurements, it is recommended to adjust for the frequency offset for the DUT measured. First, set the DUT to send a CW. Measure the frequency offset using the spectrum analyzator and adjust the frequency set on the signal generator to account for the offset.

Measurements should be done on a sufficient number of devices to give statistical significance. Ideally measurements should also be done for min and max temperature the device will be used in.
