RF WebLab is up again with the temporary PA. We most likely developed a bad contact in one of the bias lines, resulting in degraded performance of the PA.
We expect to switch back to the regular WebLab PA is about 2-3 weeks.
Best regards,

We noticed that since yesterday (June 17) the performance of the temporary WebLab PA has degraded. We will investigate next week.
RF WebLab is not available until then.

To facilitate some special experiments, RF WebLab results will deviate from normal starting Monday, March 22nd.
Later, it will be announced when RF WebLab is expected to be functional as normal.

We succesfully replaced the broken component in RF WebLab today. The system is up and running again.
We also took this opportunity to slightly reduce the ACPR asymmetry, as illustrated by the screenshots below. This is actually a return to an old configuration as existed before.
Enjoy your continued use of RF WebLab!
Koen Buisman on behalf of the RF WebLab team.
The new hardware has arrived. Hopefully it will be an easy replacement of the defective component.
I’ll keep posting updates here.

After investigation we found one defective component in RF WebLab. A replacement has now been ordered.
I’ll keep posting updates here.

I regret to inform you we most likely have a hardware failure in RF WebLab. This means for now WebLab will be unavailable for an undetermined time.
I will keep posting updates here.

RF WebLab is up and running again. Most likely some network connectivity issues happened during the weekend, impacting all traffic to and from RF WebLab. After restarting the RF WebLab server today, it seems everything is working fine again.

I have noticed WebLab is down. Even remote access to WebLab is down, therefore I have no means to investigate. Hopefully Monday someone will be available to take a look. I will keep you updated.

We’re planning to change back the to the regular DUT today at 17:00 Swedish time. We do expect that the temporary DUT will be back in the system in one or two weeks from now again.
