2008-09-16 Thread Kyle Pearson
You can connect the 1PPS to the digital io pins on the basic or lf daughtercards. From there you can use the read_io() method in python to read the value on the pins. Just make sure that your 1PPS is between about 1.5 and 3.3V; under 1.5V it may not be detected, over 3.3V you could fry a pin. -Kyl

What does it mean that USRP2 can only do MIMO with eight receivers? What are the options for doing MIMO with, say 16 receviers? Why are there two A/D converters if you can only use one RX daughtercard? Or can you actually use two RX channels with a USRP2? juha __
