Hello,
I have a USRP E310 that I'm trying to synchronize to an external 1 PPS input.
My goal is to trigger the SDR to begin receiving samples on the rising edge of
the external PPS, so I'm using a pulse generator to generate a square wave with
5V amplitude and 25% duty cycle, 1 second period
Hi,
i'm working on a custom block and have an issue with rfnoc rx streamer: my
custom block outputs at quite low data rate and i found out that rx
streamer doesn't send out anything until it receives (in my case) 16384
items. this is causing quite a lot of latency. is there any way to reduce
this
Something to note regarding the TwinRX is that changing frequency on one
channel has an effect on the other channel of the same card. I ran into
this a few years ago and never found a resolution.
My goal was to sweep with one channel and stare with the other. The
staring channel had too many
Hongwei,
In addition to the PLL that tracks the external 10MHz ref to produce the
internal 10 MHz ref, there are the four PLLs that track the internal 10 MHz
ref to produce the four LO signals (2Tx/2Rx) as you mentioned. But, the
phase variation from the LO PLLs is much less - I don't really know

Assuming 20Mhz/tuning (I think HackRF supports a maximum of 20Mhz
bandwidth), that's 2.5msec/tuning.
The X310 with the TwinRX can

Hi Marcus,
"OK, so what happens if you measure the phase-coherence just between channels
on the same USRP?"As shown in the plot in my first email, the phase is pretty
stable between channels in the same USRP.

In the startup messages, UHD should put out some commentary about setting the
Thanks, Rob and Marcus.
A single tone is repeatedly transmitted to make a continuous stream out of the
Tx antenna. It is periodically sampled in Rx; the interval is about 1s. The
sample time is aligned with the beginning of the transmitted signal to make
sure we sample at the same time across
10 matches
