We plan to change to use the ETMY ESD drivers with lower range and lower noise. To make sure that this will not saturate the drivers, we measured the spectrum of ETMX, and calibrated it with ESD OUTPUT filters, which are different for ETMX and ETMY. This should be fine because the calibrated magnitude is lower than 1000 cnts, which is much smaller than the driver's range (~130000 cnts).
