Performing real-time EMI testing using the time-domain scan method

Testing electromagnetic interference (EMI) compliance of electronic devices requires measurements of radiated emission (RE) and conducted emission (CE) generated by the equipment-under-test (EUT) under normal operation. Engineers must perform measurements to detect and analyze intermittent disturbance signals over long dwell times at each frequency, as specified by EMI testing standards. Use time-domain scan (TDS) and real-time scan (RTS), with highly overlapped fast Fourier transform (FFT) analysis bandwidth up to 350 MHz, to capture and measure gapless impulse signals accurately.

To detect EMI interference signals on the EUT, use an EMI receiver with wideband digital IF hardware and wideband time-domain scan to increase data capture bandwidth up to 350 MHz in a single segment. Sweep incoming signals continuously by setting the hold number and maximum hold incumbent signals to display all events and details of all detected signals. Use EMI measurement software to view the peak values and waterfall traces.
