hallo
did anyone can help me to check the signal strength USRP N200? because I
put a booster and I would like to see the difference?
Thanks

Subject: [USRP-users] UHD time stamps on USRP1 vs N200

We have a code that used the time spec in the metadata of the recv method
of an RX stream.
On the N200 the time stamps are very accurate (to within 1ns of what we
expect, given the previous packet's time stamp and the sampling rate).
On a USRP1 we do get time stamps, but they seem to vary in a range of about
200us. Are these time stamps derived from the time UHD got the packet on
the host, rather than the time the samples were taken on the USRP?
Thanks, Sivan

Yes. The USRP1 has no UHD timestamp functionality in the FPGA and
relies on the host system clock. The values will not be nearly as
precise.

This mailing list is not for listing items for sale, especially those which
have nothing to do with USRPs. Do not post items like this again.

Subject: [USRP-users] USRP 2920 two receive channels
Message-ID: <[email protected]>
Content-Type: text/plain; charset="gb2312"
Hi,
Is there someone here using USRP 2920? I am experimenting on it to receive two
signals separately. The problem is that when I set the channel list property
("1") for niUSRP configure signal.vi, Labview reports the error "The specified
attribute ID is not valid for the specified scope (or channel)". Is there
someone knows the reason or has some other methods?
Thanks!Wenjun

Hello Wenjun -
I answered your question on the USRP discussion forums for LabVIEW.

Hello,
We have been working with USRP1 devices for some time now and we were
thinking about buying more up to date devices.
We are thinking about the N210 devices but there seems to be only two slots
for daughter boards (versus 4 on the USRP1). We would put one SBX or WBX
card on those slots (dual slot cards).
Currently, with one USRP1 equiped with one RFX900 and one RFX2400 we can
create two transmit channels and send on both channels simultaneously (One
transmission at 900Mhz and one transmission at 2.4GHz).
My question is the following : is it possible to instantiate two transmit
channels (let's say one at 900MHz and one at 2.4Ghz) with one N210 equipped
with one SBX daughter board?
Will it require us to write some specific FPGA code or is it possible with
the stock fpga firmware?
If we can send using 2 transmission channels, would it be possible to
receive on the RX2 port on a different band from the previous 2 (let's say
500MHz for instance)?
Thanks for the help,
Jawad Seddar
