500 MHz Passive Probes

P6139B and P5050B Datasheet

The P6139B and P5050B probes are high bandwidth, high impedance 10X passive voltage probes with 10 MΩ input resistance. These probes feature a small probe head and sharp tip that makes it easier to probe dense circuitry. The P6139B and P5050B share similar electrical specifications but support Tektronix oscilloscopes with different compensation ranges. Visit the Oscilloscope Probe & Accessory Selector Tool located at www.tek.com/probes to ensure the correct probe is selected for your oscilloscope.
