LabView Services

LabView Services

Grant4Com offers limited LabView capabilities to automatize or extend practically any other tests. Monitoring voltages, currents and I/O states becomes almost trivial with the power of LabView. Additional equipment can be relatively easily integrated into measurement setup and managed centrally from one UI – a huge improvement over the normal hassle of pushing buttons and turning dials on half a dozen devices.

As an example, some of our customers have found our generic but very customizable voltage/current measurement setup useful in projects as variable as an AC-DC converter (input/output currents and voltages, power factor) and battery charger (charging in different temperatures, UVLO, charging termination, overcurrent protection). Our measurement rig is built around the following in mind:

  • NI DAQ-based logging system with variable time averaging and raw data streaming to file at high speed
  • A multitude of usage scenario generation capabilities available (radio link simulators etc.)
  • Vishay precision current measurement resistors (0.1, 0.5 and 1 Ω), direct differential inputs also available
  • Customizable current sinks
  • Only two wires need to be routed out of the DUT for simple measurements
  • EMI-proof isolation box with an antenna coupler available

Available Opportunities:

  • Current consumption in mobile devices (partial support for GSMA scenarios)
  • Usage scenario benchmarking
  • Power management configuration comparison
  • Idle vs high-power state monitoring
  • Power state transition effects in multiple voltages can be graphed
