Remote Controlling the Oscilloscope
Freewave automatically categorizes and lists the remote control
commands. To run the commands, users only have to pick and place
them on the list; no manual typing is required. The result can be
stored in CSV format.
Long Memory Length Data Capture
Freewave can take advantage of the long memory length of the
GDS-1000A-U series oscilloscopes. Waveform data can be arbitrarily
zoomed and panned with ease. Cursors can be placed on the screen
to accurately view measurements. Like the standard memory length
data capture, long memory data can be saved as a *.csv file to be
recalled at any time.
