Information about the RPW - PAS filtering tune campaign during the NECP.
General
Purpose & Objectives
Spurious signals triggered by the SWA-PAS unit have been identified during EMC ground campaigns.
Working Group Members
- Eric Lorfevre (RPW system, WG leader)
- Milan Maksimovic (RPW PI)
- Xavier Bonnin (RPW Ground Segment)
- Antonio Vecchio (RPW operations scientist)
- Diane Berard (RPW operations engineer)
- Jean-Michel Travert (RPW Command/Control)
Points of contact
- Sylvain Lodiot (MOC)
The point of contact from SWA-PAS team must be identified (might be SWA PI).

Overall timeline of the mission
Details of this campaign
The purpose of this campaign is to define the configuration of the RPW filtering parameters to be applied during the whole mission.
The four parameters to be tuned are the following:
- SY_LFR_PAS_FILTER_TBAD: perturbation duration
- SY_LFR_PAS_FILTER_MODULUS: modulus of the coarse time defining the perturbation instant
- SY_LFR_PAS_FILTER_OFFSET: offset added for computing the perturbation instant
- SY_LFR_PAS_FILTER_SHIFT: time-shift relatively to the timecode occurrence identifying the perturbation start
The operations linked to the RPW-PAS filtering tune campaign are not fully defined.
ROC
- Switch on SWA
- SWA-PAS max tension 6kV. This voltage is not verifiable in the lab à risk for BIAS
- Voltage sweep for SWA to verify the max voltage supportable by RPW.
- On flight, build up a table SWA V vs RPW V to be used during the mission.
- Validation SWA-PAS synchronization (critical for LFR) → COM or CP?? Considering a simultaneous switching of RPW and PAS during COM to test the synchro.
- S/C potential → Coordinated with SWA. Verify the possible range of values.
- Procedure to activate S20 and to require the TM. Coordinate with other instruments.
- SWA synchro
- Test of wheels filtering
