I'm a new user of the USRP equipment, I have inherited the N210 along with SBX daughter card from my lab member. However, I just noticed only RF1 is plugged into the TX/RX port and RF2 is not present on the SBX daughter card. I'm attaching the image below.
When I took a close notice, I see that the RX2 has a PCB trace that's come off (stripped) along with the SMA adapter. I think the PCB trace from SMA was supposed to connect component X1 and D5 of the schematic: https://files.ettus.com/schematics/sbx/SBX.pdf
Can someone confirm, if I'm looking at it correctly and whether it's the case of PCB trace being stripped? and have any thoughts/ideas on how to fix this? Also what is this X1 component, is it a resistor? couldn't make it out from the PCB schematic.
Please advise, any help would be appreciated. Thank you
