STEM122-16sdr oscilloscope and generator do not work

Post by arvinkhanlou » Wed Aug 21, 2019 5:35 am

STEM122-16sdr oscilloscope and generator do not work, I tried the oscilloscope app and the Jupiter notebook. No lock either way. However, using Jupiter notebook I can control LEDs and the slow analog outputs. I have manually downloaded the OS and installed it on a SD card, so the firmware should be up-to-date.

Hi,

We had an OS update since your post, is your issue persistent also with the newest version?

Hello everyone,

I have the same problem.
I tried OS images:

1. SDRlab_122-16_OS_1.03-6_stable
2. SDRlab_122-16_OS_1.04-7_beta
3. SDRlab_122-16_OS_1.04-8_beta

I have attached below the image of web GUI and results that I'm getting on in1 connector.
I have tried any combination (OUT1 -> IN1 , OUT2 -> IN1, OUT1->IN2 and OUT2->IN2), and always get the same result. Also I have tried to connect OUT1 to Tektronix oscilloscope and all I'm getting is rubbish instead of 1kHz 1Vpp sinusoid.

Can someone explain me results from attached image.
I have connected original adapter and ethernet cable and also used sd card that all came from the box: STEM lab. The version of my board is STEM122-16SDRV1r1.

Has anyone experienced the similar problem ?
Any workaround ?

Although this issue has been fixed with the new releases, there is the chance that ad blockers can also cause troubles: Guy is not loading , just showing the circles;
This happens is if you have adblock enabled in your browser.
You can disable it for the Red Pitaya unit and it will work fine. Recommended browser is an up to date google chrome.
