Key Benefits

  • Allow user to deskew the time delay between voltage and current probes
  • Easy to use and connect for current and voltage probes
  • Directly connect to USB port from oscilloscope front panel, or any USB port from Personal Computer (PC) to power up the fixture


  • InfiniiVision 3000T, 4000X, 6000X, 5000, 6000 or 7000 or Infiniium S, 8000 or 9000 Series Oscilloscopes
  • U1881A Power Measurement application for InfiniiVision 5000, 6000 and 7000 Series oscilloscopes; or U1882A Power Measurement application for Infiniium 8000 and 9000 Series oscilloscopes
  • Current Probes
  • Differential Active Probes

For accurate power measurements, it is extremely important to equalize the time delay between voltage and current probes. The U1880A deskew fixture allows you to drive both your voltage and current probes with the same pulse signal. Probe deskew can then be performed with the power measurements application software, or may be performed manually on the oscilloscope.
