One week of TBB data.

Submitter: Andreas Horneffer
Description: The image shows a dynamic spectrum generated from low band antenna data taken with the TBBs. Over the course of a week every five minutes a dataset of 10 milliseconds was taken.

The dark vertical stripes occur when the prototype readout software generated noncontinuous datasets. Bright vertical stripes are caused by strong RFI. A closer look reveals that this RFI takes the shape of trains of short pulses (see inset.) Fortunately such RFI pulses are rare during quiet times.
