Adds a high voltage differential input to your oscilloscope. The Differential probe SI-9002 extends the measurement power of oscilloscopes to power semiconductor circuits. This Differential Probe provides any general oscilloscope with a high voltage differential input.

The Differential probe SI-9002 is small and light, so it can be used in a very convenient way; just plug it into the input of, for example, the Handyscope HS5. The wide bandwidth and the high accuracy of this Differential Probe cater for a wide range of applications.

  • 1:20 and 1:200 attenuation
  • 14 ns rise time
  • 25 MHz bandwidth
  • 1000 V CAT III rating

  1. Voltage limit is the lesser of the DC+Peak AC and RMS values.
    1. The supplied voltage must be less than 12V and greater than 4.4V, otherwise the differential probe could be damaged or can't be operated properly.
    2. Polarity is "+" inside and "-" outside. For wrong polarity, built-in circuit protects the differential probe, no danger or damage will occur.
    3. When the voltage of the cells become too low, the power indicator on the panel will flicker.
