  • Beskrivelse
  • Mere information

The SI9002 is an active differential oscilloscope probe. The probe permits the measurement of signals which are not referenced to earth using a conventional earthed oscilloscope. This enables mains voltages to be tested. It is possible to measure and observe the waveforms of three phase supplies or the gate / control signals of semiconductor circuits. It is ideal for investigation of motor speed controls, uninterruptible power supplies, switch mode power supplies and process controllers.
