Another common cause of low transmit power is the contact between the
signal pin of the SMA connector and the PCB can be compromised if the
connector is over-torqued.If the trace itself is ripped off the PCB,
this is a Problem, but sometimes a blob of solder to shore up the
connection will fix

Have you checked the B205mini-i board itself to ensure the USB connector
pins are soldered down securely? There have been instances where a
dislodged connector caused USB connection issues. (If not, you can either

Hi Lukas. Most USRP X310 Linux users employ 10gigE to connect to the host
PC. PCIe on the USRP X310 uses a proprietary ASIC and the driver is, as
you discovered, built on an obsolete kernel. You could attempt to appeal
directly to NI for support if switching to 10 gigE isn't an option for you.
The N310 motherboard does not have a PCIe interface, proprietary or
otherwise. Schematic p. 20 was a PoE controller on earlier, unreleased

current to the device when both RF daughtercards were enabled. The PoE

you be more specific about how your E312 "didn't work"? It may be
possible to resurrect your E312 by means of less extreme measures.
What were you trying to do with it? Did it boot? If not, could you
connect to the device
ose connectors?

Hi Michal. The USRP2 is a discontinued product that was introduced before
Ettus Research was integrated into the National Instruments manufacturing
infrastructure.Unfortunately, the only schematics and FPGA pin
constraints files that we have on hand are the ones that you have already
located.
Hi Mark. One thought-- Vivado does not support the Spartan-3A FPGA on the
USRP N210.The JTAG protocol should in principal be the same, but Vivado
definitely does not include Xilinx device files for older FPGAs.
Have you tried to resurrect the device using Xilinx ISE 14.7 Labtools?

Easy answer-- refer to p. 8 of the schematic.

Hi Jose. The temperature ranges quotes for the B200mini in the enclosure
were derived from thermal test results. The B210 enclosure will extend
the operational temperature range, but Ettus Research has not performed
thermal testing on this configuration and we have no immediate plans to do
so.

Hi Arthur. As the Ettus Knowledge Base points out, the DBSRX2 is a very
old product and has been EOLed. The schematic is available here:

The tunable filter capability is provided by the MAX2112 IC. Datasheet

Hi Snehasish. The NI USRP 2954R has UBX-160 daugthercards and a GPSDO
module. The TwinRX is in the NI USRP 2945/2955 (with GPSDO)

Hi Jon. The XCVR2450 has been EOLed by Ettus Research. We will never
have official X310 support for this board, as it is an obsolete product.
The XCVR2450 will work with the USRP N210 or the USRP1.
Alternatively, the UBX, SBX, or CBX daughterboards will cover that same
frequency range and will
Hi Thomas. Ettus Research is preparing to offer GPIO and JTAG interface
cables for the B20Xmini series for sale in the next few months. If you
have an urgent need for one, please email supp...@ettus.com.

Hi Snehasish. The NI USRP-2942R does not actually have an integrated
GPSDO, the* NI USRP-2952R* does. That may be your problem.

Hi Roy. The hottest components on the B200mini-i are the ADI RF Integrated
Transceiver (AD9364), the Xilinx Spartan 6 FPGA (XC6SLX75-3CSG484I), and
the Cypress FX3 USB chip (CYUSB3014-BZXI). Consult the datasheets for the
max. recommended junction temperature of these devices.
