GETTING STARTED
Freewave supports the GDS-1000-U, GDS-1000A-U, GDS-2000A and
GDS-3000 series oscilloscopes and is freely available to all customers.
Freewave can transfer full screen images, video, or waveform data
from an oscilloscope to a PC via a USB connection. The software
display is updated in real-time from the host oscilloscope. Images
and movie clips can also be saved onto the PC. Images can be
printed directly to a printer.
For data analysis, Freewave is able to capture raw waveform data
from the oscilloscope and display it on the PC screen. Waveforms
can be saved in CSV format to be reused in other applications.
Freewave can also record long memory or standard memory length
waveforms with the GDS-1000A-U and GDS-2000A series.

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.

Standard Memory Length Data Capture
Standard memory length data can be directly transferred to the
Freewave screen. Up to 10 waveforms can be captured at any one
time for analysis. All waveforms can be zoomed and panned as well
as positioned vertically.

Waveform data as well as the oscilloscope identification can be
stored as a Comma Separated Values (*.csv) file which can be
opened and edited by a spreadsheet application such as Microsoft
Excel.

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 and GDS-2000A 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.
