摘要：The Level 1 of the PLANCK Low Frequency Instrument (PLANCK/LFI) Data Processing
Centre (DPC) is devoted to the handling of scientific and housekeeping telemetry. It receives raw
telemetry packets from the LFI through a tailored version of the ESA telemetry handling software
SCOS 2000, and generates time ordered information of scientific and housekeeping data to be
processed by the subsequent DPC levels. In addition, the Level 1 performs live diagnostics on the
LFI telemetry. An end-to-end test has been performed recently at the LFI integration site (Alcatel
Alenia Space, Milan) using the qualification model equipment of the on-board Data Acquisition
Electronics and Data Processing unit, and its core software. For scientific data, the test is based
on the injection of deterministic signals with known properties in the acquisition electronics and
their comparison with the signal reconstructed from the telemetry data. A regression test has
been performed on the housekeeping data by inserting known parameters values into a set of real
housekeeping packets.
