Combining Parameters for Signal Generation
Keysight 81133A/81134A Pulse Generator User's Guide, April 2015
Start Mode
When the Ext. Input start mode is selected, the instrument sends
the generated signal to the outputs according to the signal applied
at the Start In connector.
You can define the following parameters that the external signal
must meet:
• Threshold (voltage)
• Termination voltage
• Edge (rising/falling)
If you select the Ext. Input mode, the instrument automatically
switches in armed mode. This means, the instrument waits for the
selected edge to appear.
The further behavior of the instrument depends on the selected
instrument mode:
• In Burst Mode:
As soon as the selected signal appears at the input, the armed
mode is deactivated (the instrument sends one burst and then
stops).
• In Pulse/Pattern and Repetitive Burst Mode:
The instrument stays in armed mode (it sends the pattern/burst
every time the selected signal appears). The trigger output
frequency is calculated by dividing the instrument frequency by
the length of the data pattern.
Trigger Out
The trigger output can be set to one of the following modes:
• Trigger on pulse
The trigger output is generated according to the instrument
frequency. It can optionally be divided by 1 up to 2
optionally.
• Trigger on data
One trigger pulse is generated on every start of the repetitive
data pattern. The trigger output frequency is calculated by
dividing the instrument frequency by the length of the data
pattern.
