I've tried finding this number throughout code and documentation, but can't seem
to hunt it down. When using usrp_standard_rx::make(), the last parameter is
the number of blocks in a burst. What's the magic number?

Looking at gnuradio-c
If I need pin-level access to the DAC chip, sink_s is my only option AFAIK.
I understand that it's interleaved I&Q, don't worry about that.
My original questions remain.

Thanks!
I'll take a look at them later today or tomorrow.

Hi all-
Several quick questions.
1) For usrp sink_s, which bit of the short activates the MSB of the DAC
chip? I.e., if I send 0bABCDEFGH IJKLMNOP, where each letter is either a 1
or a 0, which letter matches the MSB?
2) If I want to generate a stream of alternating zeros and ones (stored in
byt

Hi, i'm an Italian student.
I'm using an Oscilloscope with Basic Tx and finding a strange behaviour sending
a costant value of 2. I see a sinusoidal wave generated from Nco (fine
modulator) + coarse modulator in this way :
32 MHz -> only coarse -> 670 mVpp
16 MHz -> only coarse -> 730 mVpp
.
