8.2.3.1 EMI

The TPSM842xx devices are all compliant with EN55022 Class B radiated emissions. Figure 23 to Figure 27 show typical examples of radiated emissions plots for the TPSM842xx devices. The EMI plots were taken using a web-orderable EVM with a resistive load. Input power was provided using a lead acid battery. All graphs show plots of the antenna in the horizontal and vertical positions.
