Rana also advised that we must use the boards which have the piggy-back amplifiers on those signals which are most useful. We referred to Alberto's thesis and chose POY55 (MICH and SRCL), REFL11(PRCL) and AS55 (DARM) as the most useful signals. We currently have these amps on AS11, REFL11 and AS55. We need to convert either AS11 or REFL11 into a POY55. Since we need to troubleshoot REFL11, I thought we might as well modify that and in the process also fix its Q output. So I renamed AS11 as REFL11 and will convert the old REFL11 into POY55 tomorrow.

I think we should leave them as is; the AS11 was made by taking into account the SB levels at the AS port and should not become REFL11. We should instead convert one of the old 25 or 33 MHz diodes into a POY55. |
