Keysight Technologies MXE EMI receiver

Keysight Technologies has added real-time spectrum analysis (RTSA) as an option for its standards-compliant MXE EMI receiver, enabling test labs to observe and diagnose transient and wideband emissions during electromagnetic compatibility (EMC) compliance and pre-compliance testing.

With RTSA, engineers can more easily see and understand high-speed transient signals that are difficult to capture with traditional spectrum or signal analysers. This is especially useful in applications such as radar, automotive and wireless communications that often experience fast-moving, short-duration emissions.

In RTSA mode, the MXE can provide real-time analysis bandwidth up to 85 MHz below 3.6 GHz and up to 40 MHz above 3.6 GHz, ensuring image-free, over-the-air diagnostics that enable faster, easier analysis of emissions. RTSA offers 100% probability of capture for signals with durations greater than 3.7 µs when viewing with an 85 MHz span.
