HV/LV jumper setting
Posted: Mon May 30, 2016 3:18 pm
Hello developers,
It is known the RP default scope utility has an HV/LV selector to correspond to the jumper settings.
Up to this point I have assumed that this was simply a gain setting, however it seems to be so much more.
When sampling a square wave signal with very high dv/dt I have noticed a "probe compensation"-like overshoot on the LV setting and almost complete elimination of this effect on the HV setting wit hthe scope utility.
My question is, presumably there is a filter on the FPGA to correct this response, what type of filter is this ?
If possible, could a link to the filter coefficients be posted ?
I am making my own acquisition utility and this is the last stumbling block
