Description of the operation
Context and objectives
The main purpose of this campaign, occurring during the NECP phase, is to characterize the Solar Orbiter payload EMC in space by acquiring RPW data.
RPW will run measurements covering the full frequency range for both magnetic and in electric sensors, in normal and burst mode. At the beginning of the campaign all the Solar Orbiter Instruments are OFF. Then they are successively set to ON. RPW will thus analyze the influence of each instrument on its measurements and on the background noise.
The EMC ground campaign planned on 2019 might be a good baseline to prepare this operation (TBC).
Operation timeline and instrument configuration overview

...
For each step, several configurations need to be tested :
- LFR: 9 different configurations in SBM1 configuration
- TDS: 2 configurations in burst mode.
- THR: all modes for equal times and sweep of all HF frequencies.
...
Run steps 1 to 13 (see next table)

The DPU SCIENCE SBM_DETECTION submode can be applied on-board during NECP, but there is not guarantee that the resulting SBM data stored on the SSMM can be downlinked to ground by MOC during this phase. (Note that the dump of the SBM data by the DPU can be forced by TC, since in the nominal case the transfer of data from the DPU SBM buffers to the SSMM is only done when an event is detected on-board.)
