## Measurement of DC-DC module and PSU

[Product](https://tinyurl.com/4639enh6)

* Directly connect scope and PSU
* 
* 
* Connecting scope and PSU with DC-DC(Prof.Bob supproted)
* 
* 
* Input DC-DC must >6V, MAX is 24V
* About [Boost Converter](https://www.gadgetronicx.com/5v-12v-dc-boost-converter/) which is a type of Switch-Regulator
* Vo > Vi -> boost
* Vo < Vi -> buck
* Basic concept: DC -> AC -> DC
* Wide input: ~24V
* High efficiency: >85%, even 95%
* High ripple noise (XX~XXX mV)
* LDO may < 1mV

## About FW of CDCFE-Prototpe

### SPI??
* Seems to have relation with *RBCP*
* 
* 

### Trigger Core
* 
* 

### SiTCP
