Today I superficially checked the LVDT driver I was planning to use for the SRM suspension.

I tested the 4 channels of each card. The Ch#0 of the left card is not working and the Ch#3 of the left card presents a lot of noise. The right card is working well.

For this test I connected the SF LVDT to the Ch#1 and the BF LVDT to the Ch#3. We can see the Ch#1 (signal K1:IOP-SR2_MADC0_TP_CH13)  and the CH#3 (signal K1:IOP-SR2_MADC0_TP_CH15) in the figure 1 and figure 2.

The peak at 960[Hz] is a leaking from the channel #31 of the ADC#0 (for timing).

• Channel 0: Not working
• Channel 1: Ok
• Channel 2: Ok
• Channel 3: Noisy  (Signal K1:IOP-SR2_MADC0_TP_CH15)

• Channel 0: Ok
• Channel 1: Ok
• Channel 2: Ok
• Channel 3: Ok
