Hello
I want to use the X300 to get a wide spectral panorama but got a slow speed.
Than I compared tune speed X300 with B200mini and got that the first loses
almost twice.
Is there correct? Which board allows synthesizer tunes in less than 10ms?
Source code and terminal screenshots in attachments.
Hello!
All daughteboards for the X310, as far as I know, allow for much, much faster
tuning times
than 10 ms. This is not true for the B200mini, on which large tuning steps can
take very long.
Are you using timed commands correctly? How are you measuring the tuning time?
Best regards,
Marcus
I didn't get your code, sorry. Maybe you can describe how you're measuring
tuning speed?
Do you have some external meter, or do you observe the TX frequency on your RX
using the
same USRP?
Best regards,
Marcus

Hi,
sadly, your approach can't be used to measure tuning time: querying the sensor
is much
slower than the tuning is. You're sampling the speed at which you can *ask* the
device
whether its LO is locked, not the actual tuning time.
If you want to measure the tuning times, I'd recommend doing so
