Behavior
Use this c ontrol window to change the trigger level preset values. This can be useful when you want to
trigger the instrument on nonstandard trigger levels.
By default:
TTL fix
es the trigger level at +1.4 V.
ECL fixes the trigger level at –1.3 V.
When you set the volts/div less than 200 mV, the instrument reduces the TTL or ECL trigger levels below
their standards. This is because the trigger level range is fixed at ±12 divisions from the center. For
exa
mple, at 100 mV, the trigger range is ±1.2 V, smaller than the standard TTL and ECL levels.
All preference settings are saved when you turn the instrument power off.
