Keysight 81160A - Pattern Source

Appendix

3.5.2 Pattern Source
Introduction
The pattern source can be Internal/External.
When selecting the internal pattern source, the 81150A / 81160A does
generate the pattern internally either algorithmically or from memory.
Additionally it is possible to provide an externally generated data stream at
MOD-IN for re-shaping by the 81150A / 81160A. To do this, select the
external pattern source.
For details on external pattern, refer to the External Patterns section.
