LabVIEW-based Data Logger for Product Validation of Commercial Equipment
Synchronizing data from multiple data logging instruments
Client – Manufacturer of commercial equipment
Challenge
The client already had a method in place to log data needed for validation testing. However, this data was acquired from multiple independent data logging applications. They needed something to aggregate the data and align/synchronize the data across multiple instruments.
Solution
Viewpoint developed a LabVIEW-based product validation solution that continued to utilize the existing data logging hardware, but uses software to aggregate & synchronize the data from multiple sources. This simplifies post-processing.
Benefits
- Synchronized & aggregated data from multiple instruments
- Ability to add capability for new instruments later on
- Real time graphing of all channels
- Channel averaging across multiple instruments
- Ability to save data acquisition configurations for future use
- Faster channel configuration than current data logging applications
System Overview
The data logging software unifies the collection of data for a particular validation test. The software configures each instrument, kicks them off, logs the data to a TDMS file, and also graphs data and displays real-time values.
