ZED X IMU sampling rate stuck at ~195Hz instead of 400Hz

Hardware ZED X
1

Issue:

According to the official datasheet, the ZED X accelerometer should run at 400Hz. However, we are observing a consistent ~195–200Hz fluctuation (when using ZED X S/N: 40200550 & ZED Box) in two separate scenarios:

  1. Real-time monitoring – ZED Sensor Viewer shows the accelerometer running at ~195Hz

  2. SVO2 playback – After recording with ZED Studio and exporting sensor data via SDK’s export sensor functions, the IMU frequency calculated from timestamps is also ~195–200Hz

Questions:

  1. Is 400Hz achievable on ZED BOX, or is there a platform-level limitation?

  2. Is this a known issue with a workaround or firmware fix?

  3. Are the SVO2 IMU timestamps reliable despite the reduced rate?
