I am seeing an issue (maybe) with mine. Channel C and D seem to have a lot more noise than A and B.
If I turn on all all inputs and set all to same voltage, time base around 1 sec, channel C and D seem much noisier.
Would like to know if others are seeing this or is there something wrong with mine.
Also, when selecting input voltage, you get an option for AC, DC or frequency however the frequency option is not working. Maybe another feature that is not there yet?
Support can you answer this one?
