Hi I havent used the new PicoScope 6.6.16 release yet, but every time I use the filters I found it would reduce the sampling count as well. There was another area of concern in : Tools, Preferences, Power management, capure rate, I use laptop on battery power because it reduces noise and noticed the capure rate was defaulted much lower than the setting power mains.
I have not experimented with this much but figured it may need attention, especialy if someone uses battery powered laptop.
Boy! the filters would get me so often till I found out they were reducing my sampling rate, ya gotta know your equipment like the back of your hand, In the automotive field, There's more than just knowing how a vehicle should function,like if that isn't enough, The test equipment becomes a big object as well, It's just lighter
