Overview
About Sensepeek SQ500 500 MHz Hands-Free Oscilloscope Probe
The Sensepeek SQ500 is the highest-bandwidth probe in the SQ series, delivering 500 MHz passive 10:1 oscilloscope measurement with just 9 pF input capacitance, the lowest capacitive loading in the lineup. The 300V RMS CAT II voltage rating and 10 M-ohm input impedance make the SQ500 compatible with any standard oscilloscope. At 500 MHz bandwidth, the SQ500 captures fast-edge digital signals, USB 2.0, LVDS, MIPI interfaces, and switching power supply transients with minimal signal distortion.

The SQ500 features the same insulated, dual-mode design as all SQ-series probes, hands-free on the PCBite magnetic base plate with articulating arm and powerful magnet, or handheld for quick point measurements. The 0.5 mm spring-loaded exchangeable test needle provides precise contact on fine-pitch components. The lower center of gravity compared to earlier SP-series probes improves stability during multi-channel measurements. Multiple ground options, color-coded cable holders, and probe tip protection are included.
