Simultaneous recording of voltage, vibration and GPS information

Summary

In drive tests of vehicles and transportation equipment, more detailed data analysis can be performed if voltage/current of batteries and motors, temperature and vibration, in-vehicle serial bus data such as CAN/CAN FD, and others  can be recorded together with speed and position information from GPS.

However, when recording the data of a vehicle in motion and the data from GPS simultaneously with a data logger, it is difficult to synchronize these data and an expensive dedicated measurement system is needed.

Measurement using a data logger often involves multiple channels and it is necessary to set the optimum range one by one according to the level of each input signal in advance, requiring a great deal of time for the work before measurement.

This application note describes the simultaneous recording of various signals and GPS information using the Portable ScopeCorder DL350.

Key Points

The DL350 portable ScopeCorder can be equipped with 2 plug-in modules selected from 18 types and  can perform combined measurement, ranging from voltage/current, acceleration (vibration), temperature, strain, frequency, logic to CAN/CAN FD/LIN/SENT in-vehicle serial bus data trend measurements.

Scope Mode: to operate as an oscilloscope

Recorder Mode: to operate as a data recorder
