When new measurement is set as active

You can also set the window to be automatically updated when a new measurement is opened as shown below.

Note that this is valid when you open a new measurement from File->Open..., but also if you select a new measurement as active from Measurement->Information... or from the Measurement Selection toolbar.

If  is checked, the lower window limit is detected as the start of the impulse response. If you are not measuring impulse responses you should not use this setting.

If  is checked, the upper window limit is set to the maximum value.
