  • Page 14: Product Description

    Product Description The Tektronix P6209 is a 4 GHz (probe only), 5X active FET probe with 1 pF input capacitance. The probe is designed primarily for use with sampling oscilloscopes, such as the CSA/TDS8000. The P6209 has a low input capacitance and high input resistance, which minimize circuit loading over a wide bandwidth range.

  • Page 15: Features And Standard Accessories

    Product Description Features and Standard Accessories The P6209 probe is provided with several features and accessories designed to make probing and measurement a simpler task. Please familiarize yourself with these items and their uses. For part number information and quantities of standard and optional accessories, refer to Replaceable Parts on page 55.

  • Page 22: Configuration

    Configuration The P6209 provides the oscilloscope with the probe model number, serial number, and attenuation factor. When connected to the oscilloscope, the display readouts are corrected for the probe attenuation factor. The probe offset control is controlled by the oscilloscope.

    Input Linear Dynamic Range The probe head amplifier used by the P6209 has a limited linear operating range. To keep the input linearity error less than 0.1%, you must limit the apparent signal input voltage to ±1.75 V.

  • Page 27: Ground Lead Length

    Operating Basics Use the DC offset adjustment to maintain the probe within its dynamic range. The nominal offset adjustment range of the P6209 is ±5.0 VDC. For example: to offset a +2 VDC level in a circuit, set the offset to +2 V.
