Cause : Illegal value for bandwidth comes when the bandwidth referred to the time slice clock cycle of the function generator has either been set too low or too high.

Depending on the time slice clock cycle, the bandwidth is defined as follows:

  • Bandwidth_max = 1 / (2 x time slice clock cycle)
  • Bandwidth_min = Bandwidth_max / 100000.
  • Check the value for the bandwidth and adapt accordingly.
