Streamlining Production

The force sense selector switch add-on unlocks the connect/disconnect function. This utilizes a fully isolated switching architecture that rapidly disconnects power from the device under test (DUT). This eliminates additional control steps, streamlines test sequences, and improves overall throughput. 

In practice, the user benefits include

  • Connect the PSMU to the device under test when ready to source current and measure voltage.
  • Disconnect the DUT electrically when changing devices, moving the probe point, adjusting the setup, or protecting the DUT.
  • Increase efficiency by eliminating the need to enable and disable current
  • Isolate the DUT between tests so the instrument is not actively connected.
  • Reduce cable handling, which helps avoid wiring mistakes and wear on connectors.
  • Improve safety and repeatability, especially in production or automated test setups.

The connect/disconnect function fully isolates the DUT from the source/measure path when the switch is open.
