## FFI Photonics Controller Interface (PCI)
* Set area scan (step: 0.1um)
* Search First Light → Output Side
* Area Scan → Out Nano
* Power Meter Chart (1DGC 2066 loss ≈ -30dB)

## SiPh_tools (Matlab-based)
* **Slave Mode** ↑ Initialized
* **Train** → output **HOM** (X: **250um**, Y: **750um**) → Select target
* Output Probe Z Controls (↑ 50um → **Find 20um**)
* After PCI Out Nano → Output Probe XY Controls → **Set**
