The Tektronix P6209 is a 4.0 GHz, 5X active FET oscilloscope probe designed for low loading, high‑fidelity sampling measurements on Tektronix SMA/TekProbe interfaces. It offers <120 ps rise time, ~20 kΩ input resistance, and sub‑1 pF input capacitance—optimized for high‑speed digital and signal‑integrity work.
Technical overview
The P6209 is a high‑bandwidth active probe intended primarily for sampling oscilloscopes (CSA/TDS8000 and TDS800 series) using the TekProbe SMA interface. It is based on Tektronix’s 4 GHz active‑probe family and shares the small, low‑mass probe head design used to access fine‑pitch SMDs.

Performance and typical applications
- Signal fidelity: The combination of 4 GHz bandwidth, low input capacitance, and high input resistance minimizes circuit loading and preserves high‑frequency content for timing, jitter, and SI analysis.
- Use cases: High‑speed digital buses (PCIe, DDR, Rambus), Gigabit Ethernet, InfiniBand, component characterization, and lab validation where sampling oscilloscopes are used.
Physical, power, and accessories
- Form factor: Small, low‑mass probe head for easy access to crowded PCBs; includes SMT KlipChip adapters and Y‑lead adapters in typical accessory kits.
- Power: The probe is powered through the TekProbe SMA interface (no separate battery in the probe head).
Compatibility and integration
- Oscilloscopes: Designed for Tektronix CSA/TDS8000 and TDS800 series sampling scopes with TekProbe SMA input; confirm your scope’s probe interface and power supply compatibility before use.
