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

Re: HV/LV jumper setting
The old wiki has some information about the digital input filter (including the transfer function), and the parameters are as follows:
KK: 0xd9999a
PP: 0x2666
HV
AA: 0x4c5f
BB: 0x2f38b
LV
AA: 0x7d93
BB: 0x437c7
KK: 0xd9999a
PP: 0x2666
HV
AA: 0x4c5f
BB: 0x2f38b
LV
AA: 0x7d93
BB: 0x437c7

Re: HV/LV jumper setting
Now that the old wiki is not accessible, is there any other place one can find this information?

hi
this information was moved into a common document which can be found here.
Jumpers are explained there in the Fast analog IO paragraph.
kind regards
