The number of individual channel or busform waveforms that can be in any given Waveform window is limited only by the amount of virtual memory in the mainframe. In testing, we stopped adding waveforms at 2,000.
The number of waveforms that can be actually viewed at one time depends on the display resolution and the size of the waveforms. With a resolution of 1600 X 1200, you can view 105 waveforms in a maximized waveform view with optional measurement tool bars disabled.
Please note that the total number of data windows (e.g., Waveform, Listing, Source, Histogram) that can be created is limited only by the amount of virtual memory.
