Thanks for your Answer,
so you mean this is the normal behaviour, that it doesnt have the same

Hi,

Is there any risk of it getting overheat since the surface of the

Hi,
I have added a block to the receive path of USRP -- between the DDCs and
rx_buffer. It was my understanding that rx_buffer would only fetch a new
sample to send through usb after "rx_strobe" was up for one clock cycle.
Therefore my block processes 32 samples of I and Q and THEN asserts

The following article states that ideally the sample values should be
symmetric about 0, when tuned to 100.1 MHz. And the values shown are between
-70 and 170:http://www.linuxjournal.com/article/7505
However my values are very big. What could be the problem?
Also when I set my center_freq to 10010
