LimeSuitemini Quicktest failure

dl2fzn · 2 March 2019 06:22

Hello,

I am using Ubuntu 18.04 with the latest version:
But the LMS7002M Test failt sometimes and the RF loopback failt every time

What can be the cause?

I am using a HP Z400, PCI USB3 card, the Limeminisdr is connected to an USB 3,0 HUB, I change this HUB, the error is the same.

@Zack, thoughts?

Zack · 4 March 2019 13:10

Do you have a chance to test it using direct connection to USB3 port? I mean not using PCIe card and USB Hub?

dl2fzn · 4 March 2019 17:01

No, there is no native USB3 at these Workstation. If I use USB2 front, I didn’t get the LMS7002M Test FAILED anymore (10 test), but the RF- loopback failure is still active (using USB2 backsides is the same issue).

If I use GQRX or Cubic SDR with the SDR I I didn’t get a waterfall from the real world (I have two other SDR and some rf measurement equipment).

Hi @dl2fzn,

Arrange RMA with Crowd Supply, please. Sorry for inconvenience.

cal70 · 13 March 2019 05:12

How do I go about getting an RMA or what ever, my new LimeSDR is dead too. Same problem as above, quickest fails out of the box

Help if someone can pls.

cal70 · 17 March 2019 23:01

Nothing from here or Crowd Source??? WTH? Board fails test, but every 3 or 4th time, it will pass - weird. BUT no help for anywhere, frustrated.

Zack · 18 March 2019 07:01

Your board is not dead. RF loopback parameters are on the edge and depends on temperature.

cal70 · 18 March 2019 12:19

Ok @Zack. TY Curious, would that change the response of the board? I have yet to get a good signal, tried the lower (88.9 - 100 Mhz) FM freq. (have read here that that may not be a good test, as a mod is required for rx… ) and then moved to the higher freq (300 - 500 Mhz) and I am still not able to get a good signal… I have tried 3 or 4 different antenna as well.

If temp is affecting the test, then I’ll see what I can do to cool down and test again. BUT why can’t I get a good RX? maybe I’m not set up right? OR is that too affected by the temp?

ADVICE?

IgnasJ · 18 March 2019 13:28

What port are you trying to use for Rx? From the test it look like you might have problems with RX1_H port.
Test results for CH1: TX_1->LNA_W (TX2_1 -> RX2_W) are on edge so it may fail because of temperature or connected cable.
However, CH0: TX_2 -> LNA_H looks suspicious as it detects highest harmonic at DC, while it should be at 5MHz. The same TX port (TX1_2) is used in the fist RF test and it passes, so your RX1_H may not be working correctly.

cal70 · 18 March 2019 14:23

Ok… not sure I understand what is going on with ‘on the limit’ stuff, but here I just ran the test again… cold LimeSDR-USB and no antennas connected (same as before) and it passes… maybe this verifies that it runs HOT?? BUT still does not address the the RX issue.

To answer @IgnasJ, I am using RX1w, I switched the connection on the board… and still no RX… well not no RX, but there is no signal above the noise. SO I must be doing something wrong, OR there is an issue OR a combination…

I appreciate the input / advice here… and any further assistance would be welcome to get me going. TY
