Types of Operations
Four types of operations are available in Freewave: Standard
memory length display monitoring, data capturing, and remote
controlling, long memory length data capturing.
Monitoring the Oscilloscope Display
The oscilloscope display contents appear in the Freewave screen in
real-time. You may store a snapshot image or video clip into the PC,
and invert the background color for better viewing. Snapshot images
can also be printed out. The oscilloscope monitor can be switched
between the Freewave screen and a simulated oscilloscope display.
When using the simulated display, all oscilloscope functions and
controls are available on a virtual oscilloscope panel.
