In this abstract, we introduce an original technique that permits to perform the full RF test of a 2.4 GHz ZigBee transmitter using a standard digital channel instead of an expensive RF channel. The solution is based on a 1-bit under-sampled acquisition of the RF signal associated with a dedicated post-processing algorithm. Results obtained through laboratory experiments as well as an implementation in a real industrial test floor demonstrate that the technique permits to implement the standard tests required to evaluate the product quality, i.e. EVM measurement, spectral mask test and power measurement.
