Sensepeek 7008 SQG15-AC passive AC probe
Details
The SQG15-AC is a complete 1.5GHz AC-coupled, low-impedance probe. One of the great features of the SQG-series of probes from Sensepeek, is the ability to use them handsfree and without the need for any other accessories.
With a passive design, 10:1 attenuation ratio and low probe tip capacitance (<1.36pF), the probe is ideal for high-speed signal measurements, by maintaining signal integrity with minimal disruption. The SQG15-AC probe provides accurate measurements across a broad frequency range, because of the flat frequency response from 1.0kHz to 1.5GHz (± 0.5dB).
The SQG15-AC is optimised 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.
