HL12 Replaced RF module
HS12 New BPM , Replaced RF module, Changed gain and offset on frontendVS12 New BPM , Replaced RF module, Changed gain and offset on frontend
HS23 It still has issue.
BPMs which didn’t work after shutdown
Aperture scan analysis: offline to online
*Comparison has to be done with two software.
