Behavior. When you select Arm on A Trig on B the oscilloscope waits for the A-Event to occur (once), before arming the
oscilloscope to trigger on one or more B-Events. Once armed, the oscilloscope does not return to looking for an A-Event.
You can use the Arm on A trig on B method on a stand alone oscilloscope, or on a TimeSync or UltraSync stack of oscilloscopes.
It can be used in Single Step or Continuous Acquisitions. It can be used with FastFrame or normal acquisitions.
When a stack of oscilloscopes is used, the acquired channels are mapped one channel from each oscilloscope in the stack. To
make the most use of these acquired channels, the Master oscilloscope unmapped channels are available for triggering. The
unmapped channels on the stack master oscilloscope are designated as MCh1, MCh2, MCh3, or MCh4 in the user interface and
the programmable interface. These channels are available for triggering when a stack of oscilloscopes is used. They are only on
the Stack Master.
On an ATI scope, Ch2, MCh1 and MCh3 are available for triggering. On a 4-channel oscilloscope, Ch1, MCh2, MCh3, and MCh4
are available for triggering.
