7. Select the Keep historical traces in subfolder option to allow the

storage of current acquisition in a separate *.osawdm file, when a

pass to fail).

³

there is no signal power in a given channel.

These historical files are stored in a dedicated folder having the same
name as the associated drift measurement file name.
