  • Page 11: Getting Started

    Getting Started The Tektronix P6243 is a 1 GHz, 10X active FET probe with less than 1 pF input capacitance. The low input capacitance and high input resistance of the probe minimize circuit loading over a wide bandwidth. The probe has a small profile and low-mass that makes probing crowded circuits fast and easy.

  • Page 12: Features And Accessories

    Getting Started Features and Accessories The P6243 Active Probe has features and accessories to make probing and measurement a simpler task. Please take a moment to familiarize yourself with these items and their uses. Probe Head Assembly — The probe head is designed for ease of use and high performance.
  • Page 13 Right-angle adapter — Use the right-angle adapter for low-profile probing of 0.025-inch diameter square pins. The right-angle adapter allows the P6243 to lie flat against a circuit board. This enables probing in vertical circuits such as computer or commu- nications backplanes, or in tight areas such as between circuit cards.

    6. If you intend to compensate the probe, refer to the user manual for your oscilloscope and perform the calibration routine now. 7. Disconnect the probe tip from the SIGNAL terminal and connect it to the GND terminal. The oscilloscope display should be at the ground reference. P6243 Instructions...

  • Page 19: Operating Basics

    Input Linear Dynamic Range The probe head amplifier used by the P6243 Active Probe has a limited linear operating range. To keep the input linearity error less than 4% you must limit the signal input voltage to ±8 V (DC + peak AC).

  • Page 20: Ground Lead Length

    When you are probing a circuit, you should always use as short a ground lead as possible between the probe head and circuit ground. The input capacitance of the P6243 and the inductance of the ground lead results in a resonant circuit that can ring. Using a shorter ground lead will minimize ringing.

  • Page 21: Figure 3: Ground Lead Equivalent Circuit

    The preceding equation shows that reducing the ground lead inductance will raise the resonant frequency. If your measurements are affected by ringing, your goal is to lower the inductance of your ground path until the resulting resonant frequency is well above the frequency of your measurements. P6243 Instructions...

  • Page 22: Figure 4: Low-Inductance Grounding

    This method is very useful when making many measurements on the same package. Using a ground plane on the package makes probing the package easier, and avoids adding unnecessary ground lead length. P6243 Instructions...

  • Page 23: Figure 5: Using A Surefoot Adapter For Grounding

    SureFoot™ Grounding If you cannot use the low-inductance grounding method recom- mended, the probe may be grounded to the package under test using a SureFoot adapter. Refer to Figure 5. Figure 5: Using a SureFoot Adapter for Grounding P6243 Instructions...

  • Page 24: Probe Tip Test Points

    NOTE. It is not recommended that pieces of solid-core copper wire be used as test points. If the wire breaks off in the probe tip socket, it may be impossible to remove the wire, and it will prevent insertion of other accessory tips. P6243 Instructions...

    Specifications The warranted specifications in Table 1 apply to a P6243 Active Probe when the probe and the host instrument are allowed to warm up for 20 minutes before measurements are taken. The warranted specifications that appear in boldface type are specifications checked in the Performance Verification section of the service manual.
