SOURce1:APCHange:SOURce EXTernal
3
Define that alternate patterns should be sent.
SOURce1:APCHange:MODE ALTernate
The following commands expand on the previous example. They cause a trigger to
be generated on the Trigger Out port whenever the user pattern is changed (from
pattern A to pattern B).
1
Define the trigger output mode.
SOURce3:TRIGger:MODE PATTern
2
Set up the trigger for pattern changes.
SOURce3:TRIGger:APATtern ABCHange
With these commands, pattern A is sent until a rising edge is detected at Aux In.
When the rising edge is detected, pattern B is sent.
1
Load the pattern to the pattern generator.
SOURce1:PATTern:SELect FILENAME,
'C:\<Instrument Model>\Pattern\ALT1s0s.ptrn'
2
Set the source for switching patterns to Aux In.
SOURce1:APCHange:SOURce EXTernal
3
Define that pattern B should be sent upon the rising edge.
SOURce1:APCHange:MODE REDGe
These commands allow the programmer to manually set which pattern should be
sent.
1
Load the pattern to the pattern generator.
SOURce1:PATTern:SELect FILENAME,
'C:\<Instrument Model>\Pattern\ALT1s0s.ptrn'
2
Select the source for changing patterns to be internal.
SOURce1:APCHange:SOURce INTernal
3
Define that alternate patterns should be sent.
SOURce1:APCHange:MODE ALTernate
4
Send pattern A continuously.
SOURce1:PATTern:APCHange:SELect AHALf
5
After some event occurs, change to pattern continuous B.
