Error Injection
Keysight N4960A Serial BERT 17 and 32 Gb/s User Guide
The N4980A multi-instrument BERT software enables users to create
their own unique patterns, and has several built-in tools to facilitate
pattern creation. A library of factory and utility patterns is provided,
such as
PRBS and clock patterns, which can be used in conjunction with custom
designed patterns in any combination to create complex patterns. Users
have a number of editing tools at their disposal, such as viewing the
pattern as a waveform, inverting a selection of bits, and finding a
sequence of bits or the longest run of ones or zeroes, all in an attempt
to assist users in what can be a tedious task.
For more information, refer to the N4980A multi-instrument BERT
software user guide.
The error injection feature can be configured either to inject a single
error or inject errors at a specified rate. Error injection is commonly used
to verify that the device under test (DUT) setup is correct when in a loop
back configuration.
A single error can be injected whether the error injection feature is
enabled or not. When the ErrInjSingle command is highlighted in the
Pattern Menu, the EXEC softkey is selected to inject a single error.
Errors can also be injected at specified rates from 10
ErrInjRate command in the Pattern Menu. For example, if 10
selected, a single error is injected approximately every thousand bits.
Error injection can also be controlled using the corresponding remote
SCPI commands.
