Unable to Extend Experiment (“Aggregate Deferred”)

[Devagopal A.M]

Hello POWDER Team,

I am currently running an experiment for spectrum data collection on the Fixed Endpoint SDR infrastructure. My experiment details are:

• Experiment Name: datacoll
• User: Deva9
• Project: PowderSandbox
• Profile: shout-long-measurement
• Reservation: Active until December 8
• Experiment Started: Dec 4, 2025, 3:03 PM

When I try to extend the running experiment, the portal reports:

“aggregate deferred”

and the extension does not go through.

Since my goal is simply to collect RF spectrum data from a fixed-endpoint USRP B210 + NUC1, I am not sure whether:

1. The extension is being blocked because one or more resources in my experiment cannot be extended,
2. The profile I am using is over-requesting resources I do not actually need, or
3. I should be using a different profile that is more appropriate for single-SDR data collection.

Could you please advise why the extension is being deferred, and whether there is a simpler or more appropriate profile for running long-duration measurements with just one fixed-endpoint SDR (USRP B210) and its NUC?

Thank you very much for your help 

Best regards,

Deva

Hi. What happened here is that your d430 modes were not
incorporated because you do not have permission to use
the dataset. So the experiment is in a bit of a holding
pattern.

Are you expecting to be able to use that dataset in RW mode?
If not, click on the modify button and remove the dataset
or the d430s from your experiment.
