DSG-850 Digital TV Stream Card

Product Overview:

The DSG-850 is a multi-format digital TV stream card independently developed by Shenzhen Xinqiyuan Technology Co., Ltd. The product features a PCI-E interface, meeting the installation requirements of mainstream PC interfaces in the market. The technical specifications of the product are precise, with high-level output, allowing for a broader testing radius without the need for signal amplification during open-loop testing. The improvement in power step accuracy enhances the product's performance. It boasts excellent MER, outstanding cost-performance ratio, and supports test streams in all formats.

The brand-new operating interface and the option to switch between Chinese and English are more in line with customer usage habits.
