What does channel add mean?
You can add the signal from one channel to the signal of the other channel this might be adding noise to a clean pulse, this might be a FM signal added with noise… The possibilities you have are huge.

FAQ 2008-01-29

Why are you offering 3 instruments in 1? What if my customer needs only one of these instruments?
In addition to precise pulses and trigger customers need to stress the device to its limits. In the past they used either a second channel or an additional instrument to distort the signal. With the new build-in capabilities real-world signals can...
