software, a powerful T&M tool that uses any USB based HD webcam and microphone to collect live data in order to monitor audio and video performance. It needs to be mentioned that additional power amplifiers and high gain directional horn antennas are required in order to boost up the signal level from the device under test as required; for the inspection software to work properly, illumination may also be required. The entire test is performed inside a fully anechoic chamber in order to block out all electromagnetic signals from the surrounding environment and make the coexistence measurement fully controlled and re-reproducible.

spectrum analyzer may also be required if very fast digital signals need to be captured. Almost all WRPM come with a display screen and a built-in loudspeaker


system as an integral part of the functionality. An inspection software can be used to detect and monitor video and audio related parameters. The inspection

software automates the detection process and also removes human errors completely from the display monitoring. Figure 3 shows the R&SAdVISE inspection


A fully compliant product gives its users more confidence. In this modern connected world and with more and more connected products joining the ecosystem every day, we should test medical products today using the RF spectral reality of tomorrow, in order to future proof the wireless performance of a device throughout its lifetime.
