    1 MW input impedance. The P6022 probe comes with a passive termination that matches oscilloscope and probe impedance, optimizes the probe performance, and provides two sensitivity settings. In the standard configuration, the P6022 probe comes with a 5 foot cable and termination. The following option is also available. Option 03...

  • Page 12: Attaching The Probe And Termination To An Oscilloscope

    CAUTION To avoid damaging the probe, do not disconnect the probe ter mination and leave the P6022 clamped around the conductor when measuring high currents. Leaving the probe cable unterminated can cause a high voltage to develop in the secondary winding which may damage the current probe transformer.

  • Page 13: Using The Standard Accessories

    Your P6022 is shipped with the following accessories: This instruction manual Read these instructions to familiarize your self with the features, specifications, and operation of the P6022 current probe. 6 inch ground lead Use the 6 inch ground lead to ground the shield around the probe transformer at the probe end of the cable.

  • Page 14: Operating Considerations

    Considerations Features and Controls Sensitivity Control The P6022 termination has a control that allows you to select probe sensitivity. The switch has two positions: 1 mA/mV and 10 mA/mV. When the control is in the 1 mA/mV position, the oscillo scope displays 1 mV for every 1 mA of current in the circuit under test.

  • Page 15: Insertion Impedance

    When you insert a conductor into the probe, you add impedance to the circuit you are measuring. This additional impedance affects signals; this is particularly important if you are measuring fast rise times. Figure 2 illustrates the equivalent circuit with additional impedance introduced by the P6022. 0.6 mH 0.2 nH .025 W...

  • Page 16: Probe Shielding

    Probe Shielding The P6022 is shielded to minimize the effect of external magnetic fields. However, strong fields can interfere with the current signal being measured. If you suspect that an external field is interfering with your measurement, remove the probe from the conductor, but keep it in the same location as when you made the suspect measurement.
