Huygens AGC test extended report available
15 Jul 1998A more detailed report on the Huygens Automatic Gain Control (AGC) test is now available. The results of the test confirm that the Huygens Probe hardware is in good health and that the depressed AGC values detected during the first two in-flight checkouts were the result of solar noise.
The Huygens off-Sun AGC calibration test was successfully carried out on 28 May at 22:04 UTC. The test lasted 33 minutes, including the two manoeuvres required to point Cassini's high-gain antenna (HGA) 12 deg away from the Sun and back. The purpose of the test was to calibrate the AGC level of the Huygens receivers in a radio-noise free environment.
