The ISI‑Fixture test board from DisaiKang Technology supports multi‑rate loss testing up to 16 Gbps with high‑precision impedance and low skew.
The ISI‑Fixture high‑speed test board is designed for multi‑rate loss applications, supporting 8 Gbps (4 GHz), 12.5 Gbps (6.25 GHz) and 16 Gbps (8 GHz). It offers excellent differential impedance consistency (100 Ω ± 5 %), ultra‑low insertion loss, channel skew under ±2 ps, and SMA connectors with up to 40 GHz bandwidth.
The board provides 16 sets of loss lines ranging from 3000 mil to 30000 mil, a mechanical size of 376 mm × 249 mm, and has been validated using a Keysight E5071C network analyzer (300 kHz–20 GHz). The document details application scenarios, key features, design considerations, and test results. This manual is written in Chinese.
