The Pulse IMUs contain a vibration monitoring tool performing a Fourier Transform in real time. This is a powerful tool to use when assessing vibrations, but while handled at lower frequencies, it can increase the motion to output latency slightly (it has no impact on the sync out ; so it doesn't impact navigation applications that handle data aging).

Before we start

The PULSE implements the sbgInsRestApi protocol over a serial interface. All available configurations and commands are detailed in the Digital interfaces page. All the examples use the sbgEComApi command line tool.

In this guide, we consider a PULSE connected to a Windows computer on the serial COM12 and using the default 921600 bps baud rate.

Export the current configuration

While it is possible to directly send a command to switch off the vibration monitoring, in this guide we will export the settings in a json file allowing for a better handling of the data.

sbgEComApi.exe -s COM12 -r 921600 /api/v1/settings/export -o config.json

Open the file in text editor and modify the following parameters:

"vibMonFft":"off",
"vibMonReport":"off"

Save the file in the file editor and send it to the IMU

sbgEComApi.exe -s COM12 -r 921600 -p /api/v1/settings/import -B configModified.json
