Pico TA274 | Tastkopf, passiv, PicoConnect 911, 40 kHz - 4 GHz 20:1, AC gekoppelt, 8 Gb/s, SMA (f)
Pico TA274 | PicoConnect 911 20:1 AC-coupled 4 GHz RF, microwave and pulse passive probe for use with any instrument having 50 Ω inputs, including oscilloscopes, spectrum analyzers, modulation analyzers and counters.
The PicoConnect 900 Series low-invasive, high-frequency passive probes are designed for microwave and gigabit applications. They deliver unprecedented performance and flexibility at a low price.The probes employ a unique (patent pending) in-PCB construction to realize extremely low capacitance, coplanar microwave integrity, robust reliability and very low cost. The result is a family of miniature interchangeable passive probe heads that cover a range of division ratios, bandwidths and coupling types.
At 1 GHz and above, and supplied by just a few manufacturers, most test probes are of familiar oscilloscope probe shape but with an active buffer amplifier within an enlarged probe body. They are mechanically complex, quite bulky, often heavy and always costly.
The PicoConnect 900 Series passive probes are designed for use with any instrument having 50 Ω inputs, including oscilloscopes, spectrum analyzers, modulation analyzers and counters, without regard to manufacturer.
