In free run mode, the execution timing is different depending on the type of computation. In the case of computations such as FFT, Filter, pulse width, etc. various data are arranged in a chronological direction. Calculations cannot be carried out during measurement. Once the measurement has been completed, the computation is performed and the results are displayed on the waveform monitor.
For computations using the four mathematical operations, exponents, logarithms, and trigonometry, you can perform them anytime during measurement (even if there was only one data available for calculation) and display the results on the waveform monitor. Please see the Computation Waveform Viewer Instruction Manual IM 707714-61E.
