Keysight 81150A - Multi-Level Pattern Definitions

7.4.1 Multi-Level Pattern Definitions
Introduction
Unlike most other pattern generators in the market, the 81150A / 81160A
allows the generation of digital data streams with 2, 3 or 4 different output
levels.
The number of levels that are used during the pattern generation is being
defined when creating a new pattern and cannot be changed afterwards.
The definition of the output level that is being used by one bit is as follows:
2 Level Patterns
Logical Bit Value/Symbol
Output Level
0
Low Level
1
High Level
3 Level Patterns
Logical Bit Value/Symbol
Output Level
0
Low Level
- (electrical idle bit)
Offset Level
1
High Level
4 Level Pattern
Logical Bit Value/Symbol
Output Level
0
Low Level
1
Low Level + 1/3 * Amplitude
Voltage
2
Low Level + 2/3 * Amplitude
Voltage
3
High Level
