Can static cause USRP work inproperly?

At least, until the day before yesterday, my flow graph works fine with
USRP

RX:

Suddenly, however, yesterday received signal strength is much lower than
normal

RX (normal):

RX (abnormal):

It looks like just a noise, but it’s a kind of rectangular pulse. (Just,
signal strength is similar to noise)

RX in normal shows count with about 1k but RX in abnormal? count with
just
tens

How could it happen?
I changed nothing but just turning on and off the USRP
