You may setup the E-mail on Event feature to save a Screen Capture, Waveform, or Measurement to the scope's internal hard drive by setting the Max E-mail Size to 'zero' MB in the E-mail on Event Setup window. You will also have to enter a pseudo recipient email address, and set the SMTP server address to 127.0.0.1 in the Email Configuration window.  You will find the setup, configuration windows in the TekScope Utilities pull down menu under E-mail on Event, Setup. For example, if you select Send E-mail on Trigger Event, and E-mail Attachments to Screen Capture, then for each scope trigger a Screen Capture image file will be saved to a default path on the scope's internal hard drive; C:TekScopeScreen Capture.
