The PAS_EM_OFF event was received during execution of PAS power on sequence AIAF016A.
It’s a normal behaviour in case DPU don’t receive any PAS HK/science packet during a period > N seconds (32 ?)
It’s a monitored parameter, that trigger a PAS SPW HeartBeat error code

The following logfile contains the detail of PAS HK packet data content (without CCSDS header) starting 2013/05/16 15:55 (just before SWA receovery at 16:00).
The first PAS HK packets are a copy of the latest HK received just before the THF event, that conduce to put PAS and EAS OFF.
Then, starting 16:00:56, all PAK HK contains 0 values, including coarse/fine time stamps ⇒ 0 correspond to time origin 2020-01-01T00:00:00
