Technical data

The parameters have the following meanings:
• ALTernate
Alternate patterns are used. The pattern that is output must be defined with
“[SOURce[1]]:PATTern:APCHange:SELect[?] ” on page 109.
• ONEShot
A single instance of pattern B is inserted into the output stream. This can be
triggered either programmatically (with “[SOURce
[1]]:PATTern:APCHange:IBHalf ” on page 108, or from the user interface (with
the Insert B button).
• LLEVel
The output pattern is determined by the level of the signal at the Aux In port.
• REDGe
The output pattern is determined by the rising edge of the signal at the Aux
In port.
N O T E
This command must be used together with the “[SOURce
[1]]:PATTern:APCHange:SELect[?] ” on page 109 and “[SOURce
[1]]:PATTern:APCHange:SOURce[?] ” on page 110.
For instructions on how to use these commands, refer to “How the Serial BERT
Uses Alternate Patterns” on page 55.
