  1. ARGOS Status/Progress ETH Zürich • Actual control software for a single DP105 • On line plot disburdens debugging • Allan variance single channel 1100MHz • Allan variance differential 1100MHz-1101MHz • DC level FFT[0] over several days of observation • Allan variance DC – channel over 62.25 hours • 300K-spectrum 250MHz x 900 sec/file with 5 spectra/sec • Sky-spectrum 250MHz x 900 sec/file with 5 spectra/sec • Radio navigation burst 250MHz x 900 sec/file with 5 spectra/sec • Hot/cold-calibration experiment with broad band noise source • Estimation sky- & system temperature of ARGOS test-receiver FFT-KTI-meeting Olten 19.08.2004 Chr.

  3. ARGOS • On line plots makes it easier to debug software • and to find optimal parameters: • top left: time signal (Yt) • bottom left: single spectrum (XY) • bottom right: dynamic spectras (XYZ) FFT-KTI-meeting Olten 19.08.2004 Chr. Monstein
