The Vector Data Logger / Interfaces Expansion
Vector Informatik hardware complements the E-Mobility Basic Measurement System and enables the acquisition of additional data from vehicle buses and ECUs as well as the recording and evaluation of all measurement data. Via PTP (Precision Time Protocol), the data is acquired synchronously with other measurement data. Thus, the internal vehicle data can be easily correlated with the measured values. The configuration is greatly simplified by transferring the measurement configuration to the VP Series Smart Loggers.
Time synchronous acquisition of measurement data from:
Measurement data recording with vMeasure log:
- vMeasure log offers the full functionality of vMeasure exp and the eMobilityAnalyzer function library. Acquired data is recorded and analyzed in parallel, and the analysis results can be used as triggers
- The smart loggers of the Vector VP Series are also ideally suited as measurement computers for demanding measuring tasks (e.g. acquisition and analysis of up to 40 measured variables at 1 MHz each).
- Easy and time-synchronous acquisition of internal vehicle data
- Parallel recording of raw data for subsequent analysis and analysis in real time
- Results of the real-time analysis can be used as triggers
