Saves the active measurement and gives it the filename '_ActiveMeas_'. The folder and extension is taken from Measurement-> Saving Defaults.... Note that if a measurement with the same name already exists, it will be overwritten.
For multi-channel measurements, channel 2 is given the name '_ActiveMeas_2', channel 3 the name '_ActiveMeas_3', and so on. This is the fastest way of saving a measurement and is well suited if another application is used to post-process measurements while measuring with WinMLS.
