DATE TIME DATA MODE COMMENTS
20000829 21:13:31.6 N/A First Power ON.
Voltage monitor registered 6.067 V (5.688-6.211 V nominal).
Temperature monitor registered 23.2 deg. C.
All other monitored housekeeping parameters
registered their default values.
20000908 03:50 - 04:05 BM2 (Burst) First burst mode data acquisition.
Some weak AKR was observed in the 125 and 250 kHz
conversion modes.
Expected interference was observed at the battery
converter frequency (65 kHz) and it harmonics, and
at the spacecraft power converter frequency (131
kHz) and its harmonics. This interference is no
more than 3 dB above the background noise level.

DATE TIME DATA MODE COMMENTS
20000829 02:01:08.3 N/A First Power ON.
Voltage monitor registered 6.118 V (5.688-6.211 V nominal).
Temperature monitor registered 24.4 deg. C.
All other monitored housekeeping parameters
registered their default values.
20000905 23:55 - 00:10 BM2 (Burst) First burst mode data acquisition.
(6th) Expected interference was observed at the battery
converter frequency (65 kHz) and its harmonics,
and at the spacecraft power converter frequency
(131 kHz) and its harmonics. This interference
is no more than 3 dB above the background noise
level.
20000906 01:15 - 01:45 TDA-8 (DSN) First DSN (Goldstone) data acquisition attempt
successful. Observed nonperiodic, "S or hook-
shaped" emissions in the range 2-4 kHz, which is
above fce. The slopes of the central part of the
S or hook varied.
20000914 14:02 - 14:17 BM2 (Burst) Observed very intense partial sinusoidal emissions
at half the spin rate. The source of this
interference is still under investigation.
20000921 17:20 - 17:35 BM2 (Burst) Observed the "S or hook-shaped" emissions at
0.4 - 2 kHz.
20000923 07:39 - 07:54 BM2 (Burst) Simultaneous data acquisition from SC1 and SC2.
20000928 19:44 - 19:59 BM2 (Burst) Fifth burst mode data acquisition from SC2 successful.

DATE TIME DATA MODE COMMENTS
20001009 10:38:13.8 N/A First Power ON.
Voltage monitor registered 6.057 V (5.688-6.211 V nominal).
Temperature monitor registered 20.4 deg. C.
