# SIGLENT Technology released new products: SDM4075A series 7½-digit digital multimeter and SAP8000D active differential probe

According to the announcement from Dingyang Technology (688112.SH), on September 17, 2025, the company will officially launch the SDM4075A series 7½-digit digital multimeter, which can accurately capture small signals, and the SAP8000D active differential probe with 8GHz bandwidth and 300fF ultra-low input capacitance.

The SDM4075A features a 7½-digit reading resolution, capable of detecting minute changes in nanovolt-level voltage, picoamp-level current, and micro-ohm-level resistance, aiding in low-power circuit design, high-precision sensor testing, and new material research. Its wide dynamic measurement range covers low-power currents up to 30A, allowing for precise analysis of IoT devices' power consumption in both standby and operational states, while also meeting the testing needs of high-power devices. It can be widely applied in manufacturing, automation, circuit design, and other fields.

The SAP8000D active differential probe, with an 8GHz bandwidth and 300fF ultra-low input capacitance, supports both differential and single-ended measurements, featuring excellent common-mode rejection performance. It is suitable for high-speed serial bus validation such as PCIe, DDR, USB3.0, and Gigabit Ethernet, as well as signal integrity analysis and high-frequency circuit debugging. It can be paired with various accessories, making it adaptable to different testing scenarios such as welding, handheld, or fixture testing.

The launch of these new products reflects the company's technological innovation capabilities, market responsiveness, and product development abilities, further enriching the company's product matrix and forms, broadening the application scenarios and usage range of the company's products, which will help consolidate and enhance the company's overall competitiveness and have a positive impact on the company's future development
