It's Easy to Create Any Waveform
* Waveforms can be created, copied, edited, downloaded, and sequenced, all with a few clicks of the mouse
* Modifying waveforms is a snap with tools such as Vertical Resize and Vertical Move
* An internal memory of 60 kB is provided for storing the waveforms you create
* You can create waveforms with mathematical precision by entering math expressions using the numerical keys on the front panel.
* Waveforms with straight lines, as in pulse or digital applications, Line Draw allows you to use the mouse to draw the lines on an oscilloscope
* Freehand Draw gives the flexibility of using the mouse to draw a waveform on the oscilloscope in much the same way as with a pencil on paper
* Sum multiple channels to create complex waveforms
* Create long, complex waveforms with linked sequence operation - up to 4 waveforms can be linked together
