Genevieve, Dave:
The PEM RF Scanner produces static png images of frequency-time plots every 10 minutes. These can be viewed at https://badger.ligo-wa.caltech.edu/rfscan/pngs/
I have created a daily cronjob, which collates the previous day's worth of 144 png files and produces two MP4 movie files. One has a frame rate of 8 frames per seconds with a run time of 18 seconds for a quick view. The second has a frame rate of 2fps and a run time of 72 seconds (attachment shows the web listing of these files).
For ease of access I have added a "RF Scanner" link to the CDS Web Page
