Error Insertion

The error insertion is capable to enforce a given error ratio, and to add single errors into the data stream. Both are available in parallel.

Insertion Rate

Syntax

Description

Available Insertion Rate

:SOUR1:PATT:EADD:RATE

:SOUR1:PATT:EADD:RATE? :SOUR1:PATT:EADD:RATE NR3

Either sets or gets the error insertion rate. Only the listed error rates are available. If another value is specified while sending the command, the error rate will be rounded to the next available value.

Inserted error rate	Parameter
None	0
1e-3	1e-3
1e-4	1e-4
1e-5	1e-5
1e-6	1e-6
1e-7	1e-7
1e-8	1e-8
1e-9	1e-9

Add Single Error

:SOUR1:PATT:EADD

Syntax :SOUR1:PATT:EADD ONCE

Description Adds a single error to the generated data stream. This is available even if the cyclic error insertion is active.

Output Level

Syntax

Description

Available Output Levels

:SOUR1:VOLT

:SOUR1:VOLT?

:SOUR1:VOLT ECLLVDS

This either sets or gets the output level. The output is always AC. Specifying the output level actually changes only the amplitude of the generated electrical signal.

Parameter Level

ECL850mV

LVDS 400mV
