Application scenarios: high-speed digital signals, high-frequency analog signals, switching power supply waveform testing, etc.

2. Extensive accessories for various test environments

The FF-1500 offers extensive accessory options, including various types of probe tips and adapters, to meet the needs of different test scenarios. Whether for PCB board-level testing,

modular equipment measurement, or complex system-level testing, the FF-1500 can achieve efficient connections through flexible accessory combinations.

Advantages: multiple accessories to adapt to complex test environments, among which the high-temperature-resistant probe tip can withstand temperatures up to 155°C.

3. Fanless design for stable and reliable testing

The FF-1500 adopts a fanless design, which not only reduces operating noise but also avoids interference from fan vibration on test results. This design allows the probe during long-duration testing

to still maintain stable performance; it is particularly suitable for laboratories and production lines with extremely high requirements on the test environment.

Advantages:

No fan-induced vibration: ensures test result accuracy.

Low-noise operation: suitable for precision measurement in quiet environments.

High reliability: reduces the risk of mechanical failure and extends equipment life.

4. Intelligent control software improves test efficiency

FF-1500 supports intelligent control through dedicated software; users can adjust probe parameters and monitor probe status in real time via a computer or mobile device.

This function greatly simplifies the test process and improves work efficiency.

Software functions:

Display probe status

Battery level display

Turn the probe module on and off

Auto-zero function

Display communication status

5. Extremely low test noise ensures signal fidelity

FF-1500 adopts advanced noise suppression technology in its design, resulting in extremely low test noise and effectively preventing external interference from affecting the signal.

This feature makes it perform well in high-sensitivity testing, especially suitable for weak-signal and high-precision measurement.

Advantages: high signal-to-noise ratio ensures the accuracy of test data

6. Dual power supply modes: laser power supply and battery power supply

FF-1500 provides two modes, laser power supply and battery power supply; users can flexibly choose according to actual needs. Laser power supply mode is suitable for long-duration continuous testing,

while battery power supply mode is more suitable for mobile testing scenarios.

Laser power supply:

(1) No need for frequent battery replacement; suitable for laboratory environments.

(2) Provides stable 7X24-hour power supply, ensuring test continuity.

Battery power supply:

(1) High portability; suitable for outdoor or mobile testing.

(2) Up to 30 h battery life (at room temperature), meeting daily testing requirements.

7. High compatibility; compatible with various oscilloscopes

The FF-1500 uses a BNC interface to connect to oscilloscopes and is basically compatible with all oscilloscopes on the market, whether Tektronix, Keysight, or Rohde & Schwarz oscilloscopes,

The FF-1500 is compatible with all of them, ensuring convenience and efficiency in testing.

Advantages:

Compatible with multiple test scenarios, reducing equipment procurement costs.

No additional adapter is required; direct connection improves test flexibility.

German PMK's FF-1500 optically isolated probe, with its 1.5 GHz ultra-high bandwidth, extensive accessories, fanless design, intelligent control software, extremely low test noise,

high compatibility, and dual power supply modes, has become a benchmark product in the field of high-speed signal testing. Whether in research laboratories or industrial production lines,

the FF-1500 can provide users with efficient, accurate, and reliable test solutions.
