The Tektronix P6209 is a 4.0 GHz, 5× active sampling probe designed for SMA/TekProbe inputs on CSA/TDS8000-series sampling oscilloscopes; it delivers <120 ps rise time, <1 pF input capacitance, 20 kΩ input resistance, and a ±2 V dynamic range, optimized for low-loading, high‑fidelity probing of fine‑pitch SMDs and high‑speed digital links.
| Parameter | Value | Why it matters |
|---|---|---|
| Bandwidth | DC to 4.0 GHz (‑3 dB) | Supports multi‑GHz digital/serial signals. |
| Rise time (guaranteed) | <120 ps | Determines ability to resolve fast edges. |
| Attenuation | 5× | Matches scope input range while preserving SNR. |
| Input resistance | ~20 kΩ (typ) | High impedance reduces loading on DUT. |
| Input capacitance | <1 pF (typ) | Low capacitive loading preserves signal integrity. |
Dynamic range and offsets: The probe supports approximately ±2 V dynamic range with ±5 V DC offset range for level shifting; maximum nondestructive voltage is typically ±30 V (DC + peak AC) — avoid exceeding this to prevent damage.
Linearity & offset drift: Linearity ±0.1% at DC and DC offset drift ≈150 μV/°C (probe only); system on‑screen offset display drift is tighter when used with TekProbe/TekConnect interfaces.
Probe head: Small form‑factor probe head and a 1.37 m output cable terminating in an SMA for sampling oscilloscope inputs; designed for access to fine‑pitch SMDs.
Included accessories: Typical kits include ground leads, spring adapters, SMT KlipChip adapters, pogo pins, probe tips, color bands, and carrying case — useful for reliable contact on tiny pads and IC pins.
