• TTL trigger level sets the trigger level to recognize the High/Low
condition in a TTL signal automatically.
• ECL trigger level sets the trigger level to recognize the High/Low
condition in an ETL signal automatically.
• Set to 50% trigger level sets the trigger level to the center of the
High/Low value of the waveform currently displayed. This setting is
useful when the trigger level is beyond the display.
•Gate
Press F2 on page 3/3 to set the logical gate combination of the
channel.
• Condition
Press F3 on page 3/3 to set the pulse width and qualifying condition.
You can set the pulse width by turning the rotary switch. There are
4 conditions for your selection:
• The “less than” (<) qualifier sets the instrument to trigger on a
pulse width less than the time value.
• The “greater than” (>) qualifier sets the instrument to trigger on a
pulse width greater than the time value.
• The “equal” (=) sets the instrument to trigger with equivalent to
the time value.
• The “not equal” (≠) sets the instrument to trigger with not
equivalent to time value.
The High condition sets the voltage level to greater than the channel’s trigger level.
The Low condition sets the voltage level to less than the channel’s trigger level.
