Ooops sorry, elaborate:

The goal is to get a Logic representation of all Analog Channels.

Today there's only one Math function in Rigol Scopes (displayed as 'Deep Blue). To get the Math function represent CH.1 as logic '0'/'1', a Math = 'A or B' can be defined for example, where A is sourced by Ch.1 & B by Ch.2 (tied to Ground). Now the 'Deep-Blue' Math display represents Ch.1 digitally.

My question is whether it is possible to defined 2 Math functions for the 2 channels (or 4 for 4)

Example:

Math set to the logic option. And the logic equations are defined as,

Math-1 = A or GND

Math-2 = B or GND

Math-3 = C or GND

Math-4 = D or GND

Where A is sourced by Analog Ch.1 (with the appropriate Threshold defined for Ch.1)

Where B is sourced by Analog Ch.2 (with the appropriate Threshold defined for Ch.2)

Where C is sourced by Analog Ch.3 (with the appropriate Threshold defined for Ch.3)

Where D is sourced by Analog Ch.4 (with the appropriate Threshold defined for Ch.4)

with the option to display only Math-1, Math-2, Math3, Math4 (and not as an overlay).
