We found an isolator was not isolating as expected. This isolator has been replaced. This hardware change may slightly change your results compared to before.

We are investigating a potential hardware issue. RF WebLab will be interrupted from time to time this morning.

We are seeing some impact on the typical response time of RF WebLab. Users will notice that at times WebLab is much slower responding than typical. We are aware of this. By the second week of August this behaviour will mostly disappear.

Please, for now, give WebLab up to two minutes to respond to your request.

Best regards,

Koen Buisman.

We have updated the RF WebLab server software. This should have no consequences to normal operation. Please let us know if you experience different ‘server-client’ behaviour from normal. Also data corruption or other failed measurements could be of interest to us.

We are quite happy with the results from our alternative amplifier. For at least two weeks we will leave this amplifier in. To give some details: It has the same GaN device as the normal RF WebLab amplifier, however the harmonic terminations, matching and bias networks are different.
After the first week of August we will evaluate this choice.

To facilitate some special experiments, RF WebLab results will deviate from normal today and tomorrow.
The day after tomorrow RF WebLab is expected to be functional as normal.

We have concluded our experiments. The normal WebLab amplifier is installed and available again.
Good luck.

Our current experiment is still ongoing. Note that this is not a stable situation and results may become different at any moment.

At the moment the planning is to change back to the normal WebLab amplifier on Friday, end of day (Swedish time).

Our networks issues are resolved.
