I've been using an AD6IW wide band preamp for testing through 3456. So far, things look OK. I wouldn't call them great. I need to verify the noise head ENR that I'm using (it's homebrew). Stay tuned.
The only band so far that appear have an issue is 3456. NF is pretty bad, but my preamp is not nominal up there. The preamp is the key to making the Lime work.
I am using the the LNA_W port with inductor removed for these tests.
I am using SDRConsole to measure NF. I want to try HDSDR with the EXTIO as there are a few settings in that software that could help with the measurements.
On the transmit side, I'm working with LimeSuite. I've been doing basic phase noise testing. Numbers are running in the high 80's for dBc/Hz. As I look at the specs for the LMS7002, I should be about 10 dB better. I must be doing something wrong in the setup of LimeSuite. I am working in SXT, TBB, ClkGen etc.
I am using the TX1-1 port.
As reported earlier, External 10 MHz Ref appears to work and can be set up using LimeSuite in the ADF4002 Module.
