2 – 7
The amplitude and range of trigger signals and levels are limited
as follows:
➢
ECL or TTL threshold crossing with EXT as trigger source.
Edge Window Trigger: trigger when the signal leaves the window region.
➢
With Ch1 or Ch2 as trigger

4 divisions. The trigger threshold
on a channel is always normalized to the screen and is therefore
affected by offset and Vrange. For default configuration of 1V
FSR (125mV/div) and 0V offset, the achievable trigger levels are

0.5V.
