Trigger Output, Detected Pattern | Agilent Technologies N5980A

Programming Reference

Trigger Output

The trigger output is accessible via the root node :SOUR3

Pattern

:SOUR3:PATT

Syntax :SOUR3:PATT?

:SOUR3:PATT CLK2CLK4CLK8CLK10CLK16CLK20 Description Either sets or gets the pattern of the trigger output.

Available Patterns

Name	Parameter
Clock / 2	CLK2
Clock / 4	CLK4
Clock / 8	CLK8
Clock / 10	CLK10
Clock / 16	CLK16
Clock / 20	CLK20

Error Detector

The Error Detector channel is accessed via the root node :SENS1

Detected Pattern

:SENS1:PATT?

Syntax :SENS1:PATT?

Description Gets the pattern that is currently used on the Error Detector to compare it with the incoming data stream. This might change when the Error Detector detects a very high error ratio, and tries to synchronize with the incoming data.
