Last week Artem, Louis and I copied the new DARM filter into ITMX 76685. This week we got through the ETMX to ITMX ESD DARM transition but lost lock 12 seconds into the 20 second ITMX to ETMX transition.  Plot attached. The EX signal looks much noisier than IX, I need to check all filters are correct.

Again, as seen last week 76637, although both ETM excitations ran fine, neither ITM excitation ran. It's the same guardian code and logs that it's sending the excitations but they are not seen on the H1:SUS-ITMY_L3_LOCK_BIAS_EXCMON and H1:SUS-ITMX_L3_DRIVEALIGN_L2L_EXCMON channels. Will get help from cds team.
