High-speed differential probes with up to >4 GHz bandwidth, ±42 V differential range, and low input capacitance for probing high-speed analog and serial signals in design and debugging environments..
The HSDP Series from PMK offers top-tier performance for high-speed signal probing, ideal for R&D engineers working on switched-mode power supplies, RF front ends, and serial bus compliance testing. With models supporting bandwidths over 4 GHz and differential ranges up to ±42 V, these probes meet the needs of advanced electronics debugging and validation.
Built with low input capacitance (<0.6 pF) and 1 MΩ input resistance, the HSDP probes minimize signal disturbance during sensitive analog measurements. Each probe features standard 2.54 mm socketed tips and comes with a variety of connectivity accessories to interface with modern PCB test points.
The ±12 V input offset control extends the dynamic measurement range, while cable options up to 7.5 meters enable access to challenging test setups such as inside enclosures or EMI chambers.
Compatibility is ensured with any oscilloscope that supports BNC inputs, and the probes operate seamlessly with PMK's AP-01 battery supply or advanced USB/LAN controlled power supplies. HSDP probes are designed to be remotely managed when used with compatible PMK interfaces, and ISO17025 calibration ensures compliance for critical testing environments.
