SIGLENT SAP8000D 8 GHz Differential Active Probe | SAPBus Probe
The SIGLENT SAP8000D is made for professional engineers who need accurate high-bandwidth differential measurements. With its 8 GHz bandwidth and SAPBus interface, it is an excellent match for compatible SIGLENT oscilloscopes in advanced R&D, design validation and high-speed electronics testing. The included probe heads and accessories make it suitable for a wide range of PCB probing situations, including solder-in, socketed and single-ended measurements.
The SIGLENT SAP8000D is a high-performance 8 GHz differential active probe designed for precise measurements of fast, low-amplitude and high-speed signals. With its high bandwidth, low noise and very low differential input capacitance of 300 fF, the SAP8000D introduces minimal loading to the circuit under test, making it suitable for modern high-speed digital and RF-related measurement applications.
The probe uses the SIGLENT SAPBus interface, which provides power, communication and automatic probe recognition directly through compatible SIGLENT oscilloscopes. No external power supply is required. When connected to a compatible oscilloscope, such as the SDS7000A series, the instrument can automatically identify the probe model and display important probe information.
With a ÷10 attenuation ratio, ±2.5 V input dynamic range, ±12 V offset range and a 20 kΩ differential input resistance, the SAP8000D is built for demanding engineering work where signal integrity and measurement accuracy are essential.
The SIGLENT SAP8000D is especially interesting for:
- Electronics engineers working with high-speed digital circuits.
- R&D laboratories developing embedded systems, communication interfaces and fast switching electronics.
- Signal integrity engineers measuring fast edge rates, differential buses and sensitive high-frequency signals.
- Design verification teams using compatible SIGLENT high-bandwidth oscilloscopes.
- Universities and technical laboratories that need professional differential probing for advanced measurement setups.
- Engineers working with USB, Ethernet, high-speed serial interfaces and differential PCB signals.
This probe is a strong choice when a standard passive probe is no longer suitable because of bandwidth, capacitance or signal-loading limitations.
