Rohde & Schwarz launched the R&S ZNA, the industry’s first purely touch-operated vector network analyzer, originally two years ago. The newly introduced models cover frequency ranges of up to 50 GHz and 67 GHz.
Rohde & Schwarz and Gemalto, a Thales company, are working on significantly reducing expensive and
time-consuming drive tests. IoT protocol stack features have been specified by 3GPP, but IoT devices have
to interact with different network configurations worldwide. This makes it important to ensure that these
features are working well in all sorts of configurations, configured by different network operators.
Thanks to the current cooperation, manufacturers of IoT solutions can use virtual drive tests during the
development phase of CAT M1 and NB IoT modules to find and fix problems at an earlier stage.
The application note contains theoretical background on OTA power and pattern measurements. It gives step-by-step instructions for the verification of the power level and the radiation pattern of a device under test (DUT) in comparison to a golden device, and it presents an approach for verifying the accuracy of beam steering.
