Setting up the A2B Analyzer (as main node) for optoA2B
The procedure to use optoA2B with A2B Bus Analyzer is as follows:
This section will guide the user to configure an OptoA2B branch network using ADI’s A2B Bus Analyzer as main node in the following configuration:
A2B Analyzer ←→ Opto A2B Sub←→ Opto A2B Main ←→ A2B Sub node DUT
| SI No. | Software Component | Version | Comments |
|---|---|---|---|
| 1. | SigmaStudio+ | 2.1.0 or later | SS+ Guide |
| 2. | A2B | 1.3.1 or later | User Guide |
| 3. | A2B Bus Analyzer | 3.4 or later | Quick Start Guide |
Please contact A2B SW and A2B Analyzer support teams for latest updates
Example Project
A2B Analyzer ←→ Opto A2B Sub ←→ Opto A2B Main ←→ A2B Sub node DUT

Hardware Requirements
| Sl. No | Name of Board | Type of Board/ Node | Quantity |
|---|---|---|---|
| 1 | A2B Bus Analyzer kit | Emulated as Main node | 1 |
| 2 | Twisted Pair A2B Cable | DuraClik connector on one end to Analyzer and Rosenberger HSD connector on one end to OptoA2B Main | 1 |
| 3 | 12V Power Supply | - | 2 |
| 4 | USB cable from PC to A2B Bus Analyzer | - | 1 |
| 5 | Audio source (non-grounded) | e.g., PC/Mobile phone | 1 |
| 6 | Aux Cable | - | 1 |
| 7 | Audio Sink Devices | 3.5mm Jack Headphones | 1 |
| 8 | AD2428WD1BZ (for emulating optoA2B only) | Primary chain-sub, Branch Main, Branch Sub - NOT required when actual optoA2B is available | 3 |
System Block Diagram
AD2428WD1BZ boards are used to emulate optoA2B sub and branch-main in the above figure.
OptoA2B Setup
OptoA2B main and DUT are present inside the EMC chamber while A2B Bus Analyzer and optoA2B sub are outside the chamber.
A2B Analyzer Settings
A2B Analyzer to be kept in Standard power Emulator mode.
Procedure
Procedure to run a Branch Network (Opto A2B) from ADI A2B Analyzer:
- In SigmaStudio+, create a schematic with the A2BBusAnalyzer platform as the main node Emulator and the OptoA2B platform as a sub node, and connect a Device under test as a sub node for the optoA2B branching chain. Schematic should be designed to have upstream audio from branch to A2B analyzer main.
- Drag an analyzer platform from the toolbox and change into main node.
- Drag a OptoA2B platform from Toolbox.
- Drag a A2B sub node as DUT & connect to branching chain and save the project.
- One-click procedure: Press Link-Compile-Download button in SigmaStudio+. SigmaStudio+ will launch the A2B Bus Analyzer automatically and discover the primary chain via .Dat file and secondary chain via command list.
- The audio streams from the DUT are now available on the main emulator for analysis and logging.
Post Discovery Branching chain register/peripheral read/write is not supported.
Once the primary chain is discovered, each secondary chain commands are taken as individual branch transactions with its own CHIP, NODEADR and PERI transactions as show below.
