Place the spring-loaded test needle on the signal, set the spring-loaded ground needle next to it and release. The flexible arm holds the probe in position, while the N52 neodymium magnet in the base keeps it locked to the base plate. The two SQ500 500 MHz passive 10:1 probes stay in place for quick measurements and long triggering sessions, with a probe ID pin that lets compatible oscilloscopes automatically select the correct 10:1 scaling. With 9 pF at the tip, they keep loading small on high-speed clocks and fast edges. No soldered wires and no fixtures.
The four SQ10 probes are designed for DC to 10 MHz measurements and well suited for I2C, I3C, UART, CAN bus and other digital signals. Color coded test wires with 2.54 mm (0.100 in) jumper connectors, often called Dupont connectors, connect directly to logic analyzers, multimeters, mixed signal oscilloscopes and debug adapters. Red and black test leads with 4 mm banana plugs connect directly to multimeters and bench power supplies.
All six probes are insulated and can be used handheld like a traditional probe. A low center of gravity keeps them stable when used handsfree, and color coded cable holders in four standard channel colors make each channel easy to trace.
Two ground options are included with each SQ500, the ground spring needle for handsfree measurements and the ground spring for handheld use, both at the full rated bandwidth. A test hook, an alligator clip and ground leads with Dupont connectors cover connections where no nearby ground pad is available.
Every PCBite holder uses the same magnetic base, knurled grip and pressure spring, with a standard working height of 50 mm (1.97 in). Each holder includes insulation washers for holding powered PCBs.
