Combining Parameters for Signal Generation Using the Keysight 81133A/81134A Pulse GeneratorKeysight 81133A/81134A Pulse Generator User’s Guide, April 2015 77Start ModeWhen the Ext. Input start mode is selected, the instrument sendsthe generated signal to the outputs according to the signal appliedat the Start In connector.You can define the following parameters that the external signalmust meet:• Threshold (voltage)• Termination voltage• Edge (rising/falling)If you select the Ext. Input mode, the instrument automaticallyswitches in armed mode. This means, the instrument waits for theselected edge to appear.The further behavior of the instrument depends on the selectedinstrument mode:• In Burst Mode:As soon as the selected signal appears at the input, the armedmode is deactivated (the instrument sends one burst and thenstops).• In Pulse/Pattern and Repetitive Burst Mode:The instrument stays in armed mode (it sends the pattern/burstevery time the selected signal appears). The trigger outputfrequency is calculated by dividing the instrument frequency bythe length of the data pattern.Trigger OutThe trigger output can be set to one of the following modes:• Trigger on pulseThe trigger output is generated according to the instrumentfrequency. It can optionally be divided by 1 up to 2 31 - 1optionally.• Trigger on dataOne trigger pulse is generated on every start of the repetitivedata pattern. The trigger output frequency is calculated bydividing the instrument frequency by the length of the datapattern.
