    Active Voltage Probes Current Probes Differential Probes Probe Connection The 2216 standard instrument is supplied with two xlO probes (Tektronix type P6109B) which are useful for a wide variety of tasks. For special measurement situations, you need different probes. Additional probes are optional (listed in Appendix A).

  • Page 314: Passive Voltage Probes

    General Purpose (High Input Resistance) Probes These are considered "typical” oscilloscope probes. Two passive probes are included with the 2216, The high input resistance of passive probes (typical 10 MO) provides negligible DC loading. Their capacitive loading however, can distort timing and phase measurements.

  • Page 315: Active Voltage Probes

    The dynamic range of active probes is typically ±10 to ± 15 V. Some active probes are also referred to as "FE E T " probes. The 2216 works with the P6202A FET probe and the 1101A probe power supply for the P62G2A.

  • Page 316: Current Probes

    Current probes can also make differential measurements by measuring the results of two opposing currents in the jaws of the probe. A variety of Tektronix current probes can be applied in the 2216 oscilloscope, including: The A6302/A6303, with an AM503 current probe amplifier in a TM502A power module, which provides you the capability to measure both AC and DC currents with one probe.
