PQ254: 1.3 GHz active oscilloscope probe

Pico Technology - PQ254

The Pico A3136 Series (ordering code PQ254) high-impedance active oscilloscope probe has minimal impact on the signal being probed with maximal signal transfer to the PicoScope 6000E Series. Its ergonomic design allows comfortable handheld use with a button to start and pause capturing in PicoScope 6.
The Intelligent Probe Interface powers the probe from the scope and facilitates automatic probe detection and unit scaling. The probe can set scope attenuation and automatically switch to 50 Ω input impedance.
With an input resistance of 1 MΩ and capacitance of 0.9 pF, this active probe offers high input impedance up to 750 MHz. These characteristics make this probe the most versatile for many of your day-to-day measurements.
