Cause : Multiple trace cannot be activated comes when the following functions or settings are not permissible in conjunction with a multiple trace (trace recorder 1):

- measuring function
- long-time trace
- trigger condition "immediate recording start" (IMMEDIATE)
- trigger condition "start with function generator" (FG_START)

- if required, deactivate the multiple trace (p4840[1] = 0).
- deactivate function or setting that is not permissible
