3.5 Run Mode Tab
The Run Mode Tab sets the mode by which the unit will run. E.g.; if the sweep starts generating the
signals when the user clicks the
Run button, or it will wait for an external trigger event. You can also
push the Run Mode button on the front panel to show the screen.

•
Run Mode – sets the way in which the signals are generated. The Enter key of the front panel will
toggle the values.
⧫
Continuous – enables running the signal continuously, as defined in the other tabs, and
regardless of the trigger events. All Trigger oriented parameters are hidden.
⧫
Trigger – enables running the signal, when a trigger event is detected.
•
Source – sets the source of the trigger. The Enter key of the front panel will toggle the values.
⧫
Timer – sets the rate for clocked triggers (in ns, µs, ms, or s).
⧫
External – an external source, connected to the Pulse/Trig-In port, issues the triggers.
⧫
Bus – a trigger is issued when the user clicks the Man Trigger button.
•
Timer – sets the rate for clocked triggers (in ns, µs, ms, or s).
•
Trigger Input Impedance – Sets the trigger input impedance value, selectable between 50 Ω and
high Z (10 kΩ).
Note: An input voltage exceeding 5 V may damage the instrument.
•
Count – sets the number of triggers that will be issued.
•
Edge :
⧫
Pos – trig on the trigger positive rising edge.
⧫
Neg – trig on the trigger negative (falling) edge.
•
Advance – sets the trigger advance either in steps or as a one-time event.
⧫
Once – sets the number of times a sweep or list will be generated. When the count is set to 0,
unit outputs signal continuously once a trigger is accepted.
