High-Speed Differential Probe HSDP4010

The HSDP Series offers best-in-class performance with >2 GHz models supporting up to ±42V differential input range, and ±8V models offering bandwidths up to >4 GHz. The high input impedance, low noise, and ±60V common mode voltage range make the different models ideal for a wide range of in-circuit measurements for design, validation, and debugging of analog signals, such as those found in switched-mode power supplies.These differential probes are also well-suited for characterizing high-speed serial bus designs, supporting widely used interfaces like USB 2.0, Ethernet (GbE), CAN/LIN, I²C, SPI, SATA, FireWire (1394b), FlexRay, and HDMI.The HSDP Series features 2.54mm (0.1”) socketed inputs, enabling easy interfacing with a variety of industry-standard connectivity options. The compact probe head design, together with a broad accessory range, makes these probes ideal for probing even the smallest IC devices.
