USRP power supply issues


#1

Hello, I was happy to be able to borrow a USRP from a friend of mine at
MIT. However, it came as just the board with two LFRX and two LFTX 1.0
daughterbouards. No power supply, cables, etc. I dug through what I
through was a rather decent pile of wall-warts that I have acquired
throughout the years but couldn’t find any for 6V. I read the ettus.com
web page where it is said that the board can operate off of 5v, But that
some boards may require 6V. Which boards are these? I have plenty of 5V
adapters that I can use while waiting for a replacement power supply.
But I don’t want to cause wierd errors due to brown outs.

Also, is there a manual for the board I can download somewhere?

Only the BasicRX and BasicTX really don’t need 6V. Everything else
basically does.
