PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2002-11-26 NOTE = "MGS RST Instrument Health Report HEA2330A.TXT" END_OBJECT = TEXT END Miscellaneous ============= We have received a replacement 36 GB hard drive from Chris Leng at JPL and intend to install that shortly on our SOPC. There have been no further spontaneous reboots, such as those reported yesterday (HEA2329A.TXT). We have participated in tests of new firewall systems at JPL. Some anomalies were repaired quickly and some procedures needed minor changes. So far as we can tell, all functionality has been maintained through the new firewall. Terry Himes coordinated the tests from JPL.

The first measurement collected at DSS 45 on day 327 (occultation 16586i, start time 2002/327-17:31:00) had free-space carrier amplitude rising about 8 dB over several minutes to normal levels immediately before ingress. This occultation was collected before the scheduled beginning of tracking. The second-to-last measurement collected at DSS 65 on day 328 (occultation 16595i, start time 2002/328-11:10:00) had free-space carrier and max SNR levels about 5 dB lower than expected. The last measurement collected at DSS 65 on day 328 (occultation 16596i, start time 2002/328-13:08:00) had free-space carrier and max SNR levels about 3 dB lower than expected.

Typical amplitudes and periods are 0.1-0.2 dB and 7 s, respectively; but much longer periods and much larger amplitudes have been seen occasionally. Two recent examples are shown in Figures HEA2330A.PS1 and HEA2330A.PS2. The first is an example of the more typical case, the second shows stronger oscillations and two modes (periods 7 and 55 s).
