Testing of the new DSP code

1 February 2008: tag NewDSP-0-1-0; tested by Heather and Jed

slot 7

  • digital: perfect scan
  • threshold: strange looking scan (fit clearly failed on all pixels). We repeated the scan twice with the same results

slot 14

  • digital: perfect scan
  • threshold: perfect scan

  • We do not understand why digital scans failed last Friday, but we successful this Friday. The only thing that has changed in the code was a minor bug in the conversion of VCAL to number of coefficients. In fact, we've seen different behaviour with the same versions of code.
  • I tried testing to see whether we can run one scan after another without initialising the ROD. The appears to fail, at least for a threshold scan followed by a digital. I suspect that this is because tasks are not cleaned up correctly once they have finished.

  • old BOC: scan did not start
  • digital: scan ran successfully; errors in data
  • threshold: scan ran succesfully; data qualitatively ok
