Hi all, I've seen some discussion about this on the email lists, but I'm still having a bit of trouble. I'm trying to use the LO IN RX ports on the front of the N310 to synchronize the oscillators on the two daughterboards. I was thinking I could generate a signal on one of the TX/RX ports of the SDR and feed that into the LO IN RX ports at the appropriate frequency and power. However, when I test this setup in GNU Radio Companion I don't get any meaningful data, so I must be doing something wrong.
The input signal that I want to sample is a 10MHz signal that is going into an RX2 port on the front end of the SDR. When I set the device argument "rx_lo_source=internal" and run it, the data I get looks exactly how I would expect. When I change the device argument to "rx_lo_source=external" and run it, I don't get anything that makes sense. Am I using the LO IN RX ports correctly? The documentation doesn't say much besides power and frequency ranges. Any help or advice would be much appreciated. -Chris
