The time values for the selected qualifier are set using the qualifier time set
softkeys ( < and > ) and the Entry knob.
4 To set the analog or digital channel patterns, press the Analog softkey or the
Digital softkey and use the binary keypad dialog to enter:
• 0 sets the pattern to zero (low) on the selected channel. A low is a voltage
level that is less than the channel's trigger level or threshold level.
• 1 sets the pattern to 1 (high) on the selected channel. A high is a voltage
level that is greater than the channel's trigger level or threshold level.
• X sets the pattern to don't care on the selected channel. Any channel set to
don't care is ignored and is not used as part of the pattern. However, if all
channels in the pattern are set to don't care, the oscilloscope will not trigger.
• The rising edge ( ) or falling edge ( ) softkey sets the pattern to an edge
on the selected channel. Only one rising or falling edge can be specified in
the pattern. When an edge is specified, the oscilloscope will trigger at the
edge specified if the pattern set for the other channels is true.
If no edge is specified, the oscilloscope will trigger on the last edge that
makes the pattern true.
