The HSDP series offers best-in-class performance with >2GHz models up to ±42V differential input range, and ±8V models up to >4GHz bandwidth. The high input impedance, low noise, and 60V common mode voltage range the different models ideal for various in-circuit measurements for design, validation, debugging of analog signals, such as used in switched mode power supplies. The HSDP probes series is also ideal for characterizing a wide range of serial bus designs, supporting the most popular serial bus interfaces, such as USB2.0, Ethernet (GbE), CAN/LIN, I2C, SPI, SATA, FireWire (1394b), FlexRay, HDMI etc.

The HSDP Series features the industry standard 2.54mm (0.1") socketed inputs that can easily interface to a variety of connectivity options available in the market. The compact probe head design, and its variety of accessories, makes the HSDP Series ideal for probing on today’s smallest IC devices.

The ±12V input offset capability extends the dynamic input range of the probe. Having an input impedance of 1MΩ || <0.6pF between the probe tips, allows the HSDP Series to be used to probe sensitive circuits without adversely loading the circuit under test.

All models are available with either a 7.5m or 2m cable length. These longer cable versions enable the user to probe remote, hard to reach test points that are impossible with the other probing solution in the market today.

The HSDP Series has a universal BNC output connector and is compatible with any oscilloscope with a 50Ω input impedance, or 1MΩ input impedance and a 50Ω feed-through termination, allowing the HSDP Series to be used on any oscilloscope in the lab.

HSDP Series’ DC offset can be controlled via remote control. The "PMK Probe Control software" provides the ability for the user to control the probe remotely via a computer, and provides the user with a graphical user interface. The software is free of charge, and included with PMK’s 2ch and 4ch power supplies PS-02 and PS-03, which are required to power the probe. The PS-02 and PS-03 power supplies all have a USB interface and are available with optional LAN interface. The 1 channel battery pack power supply AP-01 provides >8h of portable and isolated operation, which allows the user the flexibility of where the probe can be used. The AP-01 supplies power only to the probe with no software remote control.
