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.

The German PMK HSDP series low-voltage differential probes, with high performance and flexible application scenarios, are a popular choice in communications systems, test equipment, and industrial control.

Key features: 

1. High-frequency performance: 1.8 GHz to 4.0 GHz bandwidth

This means the probe can handle signals over an extremely wide frequency range and is suitable for high-frequency communications systems, RF test equipment, and industrial control scenarios requiring broadband support. Whether for 4G/5G communications system testing or high-precision RF measurement, the HSDP probe meets the requirements.

2. Wide voltage input range: ±8 V to ±42 V

The HSDP probe supports a differential voltage input range from ±8V to ±42V; this wide voltage range enables it to adapt to a variety of application scenarios. Whether for low-voltage or medium- and high-voltage signals, the probe provides accurate measurement and ensures system stability and reliability.

3. High input impedance and low capacitance characteristics

The HSDP probe has a high input impedance of 1MΩ and a low input capacitance of 0.6pF, which effectively reduces interference with the input signal when connected to high-impedance or high-speed signal sources. This characteristic is particularly suitable for scenarios requiring high-precision measurement, such as signal testing and debugging in communication systems.

4. Low-noise performance: 2mV minimum

The probe's low-noise characteristic has a minimum value of 2mV, ensuring that interference in the probe output is extremely small in high-frequency signal environments. This low-noise performance is critical for systems requiring high-precision signal processing, effectively reducing measurement errors and improving overall system performance.

5. Common-mode input voltage: ±60V

The HSDP probe supports a common-mode input voltage range of ±60V; this high voltage range enables it to adapt to more demanding industrial environments or high-voltage signal sources. Whether for high-voltage test equipment or control systems requiring interference immunity, the probe provides stable and reliable performance.

6. Differential DC offset: up to ±60V

The probe's differential DC offset range is up to ±60V; this feature enables it to automatically adjust the output under different voltage environments, ensuring stable performance even in complex power grid environments. In addition, this function supports remote control, further enhancing the probe's flexibility.

7. Remote control function: supported by PMK control software

PMK provides dedicated control software that allows users to remotely control the probe's output offset level. This function is particularly suitable for application scenarios requiring automated operation or remote monitoring, such as industrial control systems or automated test equipment. Through software control, users can adjust probe parameters in real time, ensuring measurement accuracy and system stability.

8. High robustness: suitable for harsh environments

The HSDP probe has high robustness and can maintain stable performance under ±60V voltage variations and wide-frequency environments. Its high-temperature resistance, low-temperature resistance, and interference immunity make it suitable for various complex environments, including industrial control, communication testing, and high-precision measurement.

The German PMK HSDP low-voltage differential probe, with its high-frequency performance, wide voltage range, high impedance and low capacitance characteristics, low-noise performance, and remote control function, has become an important tool in modern communications and industrial fields. Whether for communication systems, RF testing, or industrial control, the HSDP probe provides strong measurement and debugging performance, helping users achieve efficient and accurate system design and operation.
