Keysight Technologies MXE EMI receivers with real-time spectrum analysis

Keysight Technologies has announced the availability of real-time spectrum analysis (RTSA) as an upgradeable option for its MXE EMI receiver. The addition of RTSA enables test labs to observe and diagnose transient and wideband emissions during electromagnetic compatibility (EMC) compliance and pre-compliance testing.

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

In RTSA mode, the receiver 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 fast, easy 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.

Frequency mask trigger (FMT) capability is also included with RTSA, allowing users to trigger on signals with durations as short as 17.4 µs. Time-qualified triggering capability further enhances FMT by simplifying the task of finding pulse outliers or triggering on specific communications bursts.
