Can the sampling rate on the thrust stand go higher?

The sampling rate limit on each of our product is the following:

  • Series 1520: 40 Hz
  • Series 1580: 40 Hz on power sensor, 8 Hz on force sensors
  • Series 1585: Up to 80 Hz
  • Series 1780: 40 Hz

This sampling rate is not constant, and it depends on your computer.

Our tool was designed for the characterization of the overall performance of your propulsion system. It was not designed to measure and was not equipped with the processing capacity to handle acceleration and real-time reaction of the power system.

Under some circumstances, the maximum sampling rate may be capped by the serial port communication. Please follow this step:

  • Open the RCbenchmark GUI and go to Setup Tab
  • Click the button “Adjust Sample Rates”

unnamed (1)

  • Follow the guideline in the pop-up window to change the serial port setting.

If you have tried the guideline but you are still not able to reach the sampling rate that you hope to achieve, please try to:

  • Unplug the USB cable and try to use another USB port. If you are using a long USB cable or an extension, please make sure to have a hub that will supply extra power in transmission.
  • If you are unable to use another USB port, then try to use a laptop and move very close to the stand.
  • Close all running applications except RCbenchmark GUI.
  • Disable some real-time plots.

If all the measures indicated above cannot help, it possibly means that the system has reached its physical limit of the sampling rate. You may still try to use a desktop or a more powerful computer in order to enhance the processing capacity.
