Generator off

If the generator is not turned on , no output signal will be generated from WinMLS. You need to select what type of input signal to be measured from the two choices below

If Stationary is selected, the dialog will look like below.

If Transient is selected and the  button is clicked, the Various section will look like below.

If  is checked, WinMLS will wait until the input level exceeds the trigger level (in this example –30 dBFs, which is 30 dB below digital clipping). When the signal exceeds this level, the signal will be recorded and the length is given by the Length of recorded data setting.

The pre-trigger duration  determines how many milliseconds to be included in the measurement before the trigger level was exceeded.
