Appendix E: Search and Trigger Command Sequence Examples
Example 2: Single Threshold Edge Trigger
Goal: Trigger on the channel 2 waveform when the waveform crosses below a
threshold of 1.4 volts.
Command
Comment
*RST
Resets the oscilloscope. Wait for the reset to complete (approximately
3 seconds).
:DISPLAY:WAVEVIEW1:CH2:STATE 1
Turns the CH2 waveform on.
:TRIGger:A:TYPe EDGE
Speci
fi
es that this will be an edge trigger (trigger will occur when the
source waveform passes through a speci
fi
ed threshold level in the
speci
fi
ed direction).
:TRIGger:A:EDGE:SOUrce CH2
Speci
fi
es the CH2 waveform as the source waveform.
:TRIGger:A:LOWerthreshold:CH2 1.4
Speci
fi
es 1.4 volts as the threshold level.
:TRIGger:A:EDGE:SLOpe FALL
Speci
fi
es as falling edge as the direction.
:TRIGger:STATE?
Should return TRIGGER, not AUTO.
Example 3: Dual Threshold Runt Search
Goal: Search the channel 3 waveform for negative runt pulses and place a mark at
each instance when the waveform drops below an upper threshold of 1.4 volts, but
does not cross a lower threshold of -2 volts before re-crossing the upper threshold.
The pulse width must be less than 600 microseconds.
Command
Comment
*RST
Resets the oscilloscope. Wait for the reset to complete
(approximately 3 seconds).
:DISPLAY:WAVEVIEW1:CH3:STATE 1
Turns the CH3 waveform on.
:AUTOset EXECute
Autosets the displayed waveform CH3. Wait for the autoset to
complete (approximately 3 seconds).
:SEARCH:SEARCH1:TRIGger:A:TYPe RUNT
Speci
fi
es that this will be a runt search (a mark will be placed on
a pulse amplitude that crosses one threshold but fails to cross a
second threshold before re-crossing the
fi
rst).
:SEARCH:SEARCH1:TRIGger:A:EDGE:SOUrce CH3
Speci
fi
es to use channel 3 as the source waveform.
:SEARCH:SEARCH1:TRIGger:A:LOWerthreshold:CH3 -2
Speci
fi
es to use -2 volts as the lower threshold.
:SEARCH:SEARCH1:TRIGger:A:UPPerthreshold: CH3 1.4
Speci
fi
es to use 1.4 volts as the upper threshold.
:SEARCH:SEARCH1:TRIGger:A:RUNT:POLarity NEGative
Speci
fi
es to search for when the runt polarity is negative.
:SEARCH:SEARCH1:TRIGger:A:RUNT:WIDth 600E-6
Speci
fi
es a pulse width of 600E-6 seconds.
:SEARCH:SEARCH1:TRIGger:A:RUNT:WHEn LESSthan
Speci
fi
es to search for when the pulse width is less than
600E-6 seconds.
:SEARCH:SEARCH1:STATE 1
Turns the search on.
