clear

Clear a received Script trigger. The clear instruction is commonly used immediately before a wait or repeat until instruction to ensure that any Script triggers received before the wait or repeat until instructions are ignored.

Usage:

• clear scripttrigger0

Examples:

• Generate myWfmA, clear any Script triggers, wait for receipt of a Script trigger, then generate myWfmB:
  generate myWfmA
  clear scripttrigger0
  wait until scripttrigger0
  generate myWfmB
  
  Without the clear instruction, any Script triggers received during generation of myWfmA would cause myWfmB to be generated after the smallest possible delay.
• Continuously step between three waveforms, waiting for a Script trigger between each:
  repeat forever
      clear scripttrigger0
      wait until scripttrigger0
      generate myWfmA
  
      clear scripttrigger0
      wait until scripttrigger0
      generate myWfmB
  
      clear scripttrigger0
      wait until scripttrigger0
      generate myWfmC
  end repeat

Note  Script trigger detectors are cleared automatically when Script triggers are "consumed." For example, you do not need to put a clear instruction between the wait instructions in the following script: generate myWfmA wait until scripttrigger0 wait until scripttrigger0 generate myWfmB

The device waits for two Script triggers to occur before generating myWfmB. The same situation is true when a Script trigger is "consumed" by a repeat until instruction or an if/else/end if instruction.
