暫滅組員意見如下

Spec:
Four Quadrant
Four wire
>= 100W each
>= 30V each
>= 3A each
>= 16bit readout resolution
Isolated
34401 form factor
Color Display

簡單講而家部機個結構, 有3片PCB
1. LT1970A Amp+DAC+ADC做core, 食+-36V, GND, SPI Signal
2. +-36 Rail Regulator Amp + STM32F0做control, 出入 SPI Signal
3. STM32F7做 UI, Touch LCD, LAN, USB, etc. 出SPI Signal比 STM32F0

Budget?

有咩用?像限顯示原理只見network analyzer用

34401 form factor即係幾大?
>= 100W each 做loading時cooling會唔會有難度?
留名學野
