Data Logging: Performing Long-Distance Remote and Distributed Data Logging

Data Logging: Performing Long-Distance Remote and Distributed Data Logging

Application Notes

In this measurement brief we will discuss two low-cost ways you can perform long-distance and distributive data logging. The explosion of wireless connectivity across the globe has led to a wide range of off-the-shelf wireless networking products. The majority of these products have one thing in common: they can connect to an Ethernet network. This capability means they can serve as an I/O pathway for measurement instruments that have an Ethernet port. Instruments that are built on the LXI standard have this capability. With this type of setup, the computer that controls the instruments and records the measurements does not have to be located with the instruments. Now, when you perform long-distance remote data logging, you no longer have to make frequent trips to the test site to start tests or retrieve logged data. This is especially true when you use smart instruments that have built-in data-logging capabilities like the 34410/11A DMMs.

In this brief we will look at two low-cost ways to do remote and distributed data logging:

  1. Via a long-range Ethernet bridge
  2. Via a cellular router
