Experiment Data System (EDS)

Mission: XTE.

The EDS consists of eight Event Analyzers (EA), of which six are dedicated to the PCA and two to the ASM. Each EA contains an Intel 80286 processor and associated memory. The EAs can be programmed independently to process incoming events from the instruments in any of the following modes:

  • Transparent mode, using 1, 2, or 3 EAs
  • Event mode, using 1 or 2 EAs
  • Binned mode (time and/or energy)
  • Burst catcher mode
  • Fourier transform mode
  • Pulsar fold mode
  • Autocorrelation mode
  • Arrival time differences histogram mode
It was built by the CSR at MIT. The principal investigator is Dr. Alan M. Levine.
