I've been slowly working to understand/isolate an issue with a strange voltage pulse at all freqs and on USRP N210 with 50 Ohm load.
I posted about it on StackExchange here, and there are more details at this link: http://stackoverflow.com/questions/27968237/semi-consistent-voltage-pulse-from-usrp-when-using-simple-gnu-radio-flowgraph
Since then, I've further isolated it as a UHD issue by completely removing the GNU Radio scheduler from the equation and simply using the finite_acquisition function on UHD to pull samples directly into Python.
Here is the code I'm using to produce this output http://i.imgur.com/c3YWA22.png:
An interesting thing is that when using the UHD driver is used outside a flowgraph (uhd.finite_acquisition), I get the strange pulse consistently, whereas when used in a flowgraph it was inconsistent (see the StackExchange question).
