The comparison between the new and old MC servo (FSS part) was attached.
- The new servo has the same DC range as before.
Even though there is 1/2 gain in the chain now, the previous range of the FSS box was 0 to 10V.
Now it is +/-10V. So we did not lose the range.
- The new servo has x3.2 larger range above 100Hz.
- x1.6 enhancement of the FSS Box output noise above 10Hz.
- The noise of the HV amp (and the summing amp) is x300 and x2600 more filtered at 10kHz and 100kHz respectively.
