Those are probably jumps due to instantaneous changes in the frequency control in the internal TCXO. Try injecting an external 10 MHz reference clock and using that instead to see if it makes the jumps go away. Jason On 7/23/20 8:31 AM, Don Kelly via USRP-users wrote: Any other usrp-users usin

[USRP-users] N320 inverted spectrum when tuned below 450 MHz

2020-10-14 Thread Jason Roehm via USRP-users
I have an N320 that I'm trying out for the first time. I'm using UHD 4.0.0, and I loaded the corresponding root filesystem data for that release to the N320. I find that when the receiver is tuned to frequencies below 450 MHz, the spectrum is inverted. When you tune to 450 MHz or above, the spe

Ron, Can you elaborate on what the changes you referenced are and their consequences? In my past experience, increasing the frame size has been critical to achieving full-rate throughput on the B200 series. Jason > On Feb 8, 2019, at 3:45 PM, Ron Economos via USRP-users > wrote: > > The rec

[USRP-users] X300 REF OUT drive capability

2019-02-12 Thread Jason Roehm via USRP-users
How much current can the X300 REF OUT port drive? I have another device that has a reference input with a relatively low input impedance, and I want to ensure that it can source enough current to properly drive it. Thanks. Jason ___ USRP-users mailing

[USRP-users] X300 with TwinRX and LFRX under UHD v3.14

I have a software application that interfaces to an X300 with a TwinRX daughterboard installed. We recently upgraded our UHD version to v3.14.1.0 in our application. Since then, we've observed that the time_spec values on consecutive blocks of data received from the unit (i.e. from two sequenti
