Safety Information
Prevent personal injury, fire and product damage.
To avoid personal injury and to prevent fire or damage to this product or products con-
nected to it, review and comply with the following safety precautions. Be aware that if you
use this probe assembly in a manner not specified the protection this product provides
may be impaired. Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Do not connect the differential probe’s ground input to a potential other than earth ground.
Alwaysmake sure the probe and the measurement instrument are grounded properly.
Connect and disconnect properly.
Connect the probe output to the measurement instrument. Optionally connect the
differential probe’s ground input to earth ground before connecting the probe’s differential
inputs to the circuit under test. Disconnect the probe inputs and the probe ground
connection from the circuit under test before disconnecting the probe from the
measurement instrument.
Observe probe and probe accessory ratings.
Do not applyany electrical potential to the probe inputwhich exceeds the maximum ratings
of the probe or the accessories connected to it. In a combination always the lower rating /
measurement category applies to both probe and accessories connected
to it.
Do not operate with suspected failures.
Refer to qualified service personnel.
Indoor use only.
Do not operate in wet or damp environment. Keep the product dry and clean.
Do not operate the product in an explosive atmosphere.

About HSDP Series
The HSDP series offers best-in-class performance with >2GHz models up to ±42V differential input
range, and ±8V 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.
Individual Connectivity Accessories for Highest Signal Fidelity
The input offset capability extends the input range of the probe. Having an input capacitance of
<0.6pF || 1MΩ between the probe tips, allows the HSDP Series to be used to probe sensitive circuits
without adversely loading the circuit under test.
Differential Input Impedance Input Impedance to Earth Ground
The HSDP-Series uses a PMK custom high speed FET input amplifier that provides a superior high
frequency response, as well as low noise and low distortion to accurately capture the signals being
measured.

HSDP Series Manual

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 tocontrol 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, PS2 and PS3, which are required to power the probe. The PS2 and PS3 power supplies have
a USB interface as well as an optional LAN interface. The new AP-01, 1 channel battery pack power
supply, 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.
