Hi all,
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:
In general you cannot use the first few samples of output from an
acquisition. There are a couple of reasons:
First, if you begin collecting data immediately (rather than using UHD to
schedule a collection at a given time) and you are using a daughterboard
with a downconverter (anything but

Second, there are digital halfband and CIC filters in the USRP, and
they are not reset between acquisitions. This means that the first
samples will have some junk left over from the last acquisition.
If the filters were reset, what would they be

I don't think it's tuning effects, if I'm understanding that
correctly. You mean that after you retune the USRP, the LO will take
some time to settle?
In the script I posted, that shouldn't be a factor, as the UHD
