  • Page 23: In Detail

    Handheld Operation The P6015A probe is designed for handheld use when used with the straight or hook shaped probe tips. When using the straight tip, the probe should be held by the plastic handle, behind the probe guard ring, and the tip should be held against the high voltage test point.
  • Page 24 Readout If your P6015A has the readout option and is being used with an instrument having readout capability, the display automatically corrects for the probe attenuation factor. (Refer to Overview on page 1–1 for information about the P6015A readout option.)
  • Page 25 In Detail NOTE. Some oscilloscopes may misinterpret the 1000X attenuation code. Contact your local Tektronix representative if you have questions. Probe Placement CAUTION. Probe placement can be critical in some applications. To minimize Device-Under-Test circuit loading, the P6015A input resistance is very large and input capacitance is very small. Small changes in capacitance near the input resistor will affect the accuracy of the measurement.

    However, because of the 1000X probe attenuation, the system will not display sufficient deflection for optimum adjustment of transient response unless a calibration generator having higher amplitude output is substituted.
