Hi All,

As asked in today's forward upgrade meeting, we have discussed with Gerard about the meaning of the VPSP.

From the CMS documents: The analog baseline of the APV output signal is controlled by the VPSP setting.

Gerard confirms that the VPSP sets the baseline of the APV output signal. Ideally we should have the lowest pedestal a bit above the saturation point. And all the pedestals should be below 2000, which we are having now.

Best,
