Sensepeek 7012 SQG60-AC passive AC probe
Details
The SQG60-AC is a complete 6.0GHz AC-coupled, low-impedance probe. One of the great features of the SQG-series of probes from Sensepeek, is the ability to use them hands-free and without the need for any other accessories.
With a passive design, 10:1 attenuation ratio and low probe tip capacitance (<1.31pF), the probe is ideal for high-speed signal measurements, by maintaining signal integrity with minimal disruption. The SQG60-AC probe provides accurate measurements across a broad frequency range, because of the flat frequency response from 1.15kHz to 4.8GHz (± 0.5dB).
The SQG60-AC is optimized for use with instruments featuring a 50Ω input impedance, and is therefore useful in many high-frequency applications, including oscilloscopes, network analysers, and spectrum analysers.
