Hi,
What is the voltage level for the USRP external clock? Is 1V peak to
peak ok? I am planning to drive the board using a high accuracy
reference clock.

2.6.3 and 2.8.6 work. So it was something to do with WX 2.8.4. Go

I looked it up from the schema. It seems that a basic 1V peak to peak
should be fine.

OK I did some more trouble shooting to narrow down the problem. I
decided to start with C++ code from a block that I knew already
worked.
I extracted the file gr-howto-write-a-block-3.0.4.tar.gz. I then
installed the block using the normal configure, make, and make
install procedure. I then

Hi all:
I have two questions about Gnuradio latency:
1. In transmit path, the USB delay is constant due to the 32KB buffer
between signal source output and USB. If the sampling rate is 1MS/s and
each sample is complex 16 bits( sample size=4bytes), we can get the USB
latency = 8ms. But how do

You misunderstand how things work.
Please take a look at Thomas
Hi Eric:
I have already read that paper before. As that paper mentions, the USB delay
is according to the equation
f(512, fusb_block_size*fusb_nblock)
-
fs*sample_size , which
f(x,y) is at least x and at
I'm using a USRP and the usrp_rx_cfile program to record data for later
processing. When I graph the recorded data, it looks choppy as if I
need to sample at a higher rate. I have done a few runs at various
decimation rates and I'm confused by the resulting file sizes. When I
set the decimation
