  • Page 37: Configuration

    Configuration The P7260 provides the host instrument with the probe model number, serial number, and attenuation factor. When connected to a host instrument with a TekConnect interface, display readouts are corrected for the probe attenuation factor, the instrument input is set to 50 , and the coupling is set to DC.

  • Page 38: Figure 4: Dynamic And Offset Limitations

    Configuration NOTE. The P7260 has a ±5.0 V offset range which can be measured in 5X or 25X gain using offset. The linear operating range at 5X is ±0.75 V. The linear operating range at 25X is ±3.0 V. See Figure 4, below.

  • Page 39: Operating Basics

    Please follow these operating guidelines to get optimum performance from your P7260 probe. Handling the Probe Exercise care when using and storing the P7260. The probe and cable are susceptible to damage caused by careless use. Handling. Always handle the probe using the compensation box and probe head, avoiding undue physical strain to the probe cable, such as kinking, excessive bending, or pulling.

  • Page 40: Input Linear Dynamic Range

    Refer to instructions for manually changing attenuation of the probe, or use the GPIB commands available on your host instrument. The probe head amplifier that the P7260 uses has a limited linear operating range. Refer to Table 6 in the Specifications section for dynamic range and linearity limits.
