I did not have a proper fine pitch GSG probe or anywhere to land it, so I created a crime against metrology consisting of a pair of SMA cables off the front of the VNA, a pair of SMA to dual 0.1” pin header adapterss (yes, these exist), a pair of single ended 0.1” extension wires, and a set of PCBite SP10 probes. It wasn’t the slightest bit impedance matched and I had no way to calibrate it (as a rough baseline, insertion loss was somewhere in the vicinity of -10 dB with the probes touching due to all of the reflections in the setup) but for narrowband measurements where I just wanted to check if the crystal was resonant or not, it would do.

更深一层的挑战,在于各地以高额补贴、场景开放争相“引虾入池”时,资源的集中倾斜难免在不经意间扭曲创新的自然流向。一些犹豫不决的企业,可能因政策和舆论的鼓动“跑步进场”,但没人能打包票他们能够成功。更有甚者,部分企业可能从“攻坚核心技术”转向“包装概念以适配政策”,催生出追逐短期红利的“套壳智能体”。这不仅消耗宝贵的财政与算力资源,更可能挤出那些专注底层,却未必符合“热点标签”的真正创新。
