I have an MSOX-4054A scope with firmware V04.08.2016071800. For the life of me I can't get the setup/hold trigger to work. I can set the setup time to up to <10 seconds but the max allowable hold time is stuck at <10nS. The scope is hooked up to a relatively slow serial bus with expected setup/hold times in the uS range. Consequently, it never triggers.
