Error Addition in the Pattern Generator
[SOURce[1]:]PATTern:EADDition ONCE|<boolean>
This is a contraction of the phrase: Error ADDition and is used to control the addition of
errors into the generated pattern. The parameter ONCE causes a single bit error to be
added to the pattern. It also turns off the constant rate error addition.
A boolean parameter enables/disables the addition of errors at a fixed rate.
The *RST selection is OFF.
[SOURce[1]:]PATTern:EADDition:SOURce EXTernal|FIXed
This command controls the source of injected errors. When set to EXTernal (and
:EADDition[:STATe] is ON), each pulse at the External Errors socket causes an error to
be added to the data stream. When set to FIXed (and :EADDition[:STATe] is ON),
repetitive errors are internally added to the data stream. The rate of error addition is
controlled by the :EADDition:RATE command.
The *RST selection is “FIXed”.
[SOURce[1]:]PATTern:EADDition:RATE <numeric value>:
This command controls the rate of internal, fixed error addition. Values between 1E−3and
1E−9 in decade steps are permitted.
