See more in the Frequency Domain with Real-Time Spectrum Analysis (RTSA). All MXR-Series models come standard with 40 MHz of analysis bandwidth for DDC and RTSA on one center frequency, with options for 160 or 320 MHz of analysis on 4 or 8 different center frequencies. RTSA is ideal for testing fast changing signals. For example, highly dynamic Bluetooth data is difficult to capture consistently with standard FFT but easy with RTSA. RTSA’s speed of 200,000 FFT plots per second mean that even bursty Bluetooth data is captured easily, while nearly invisible with the usual FFT (~1,000 plots per second).
