Line Test Box LTB 1024
Flexible voltage and current monitoring in A2B® -networks
The Automotive Audio Bus (A2B®) by Analog Devices Inc. reduces the complexity of audio systems. In addition to the automotive industry, it is also increasingly used in other areas such as conference systems.
We have specifically developed a line measuring device for this A2B® -technology:
The Line Test Box LTB 1024.
This compact device reliably measures bus voltage and bus current between A2B® -nodes during bus operation. In addition, you can use the innovative box to simulate faults on both A2B® -lines or to perform load simulations.
THIS IS WHAT DISTINGUISHES OUR PRODUCT
Features & Specifications
- Measures the voltage, current, and power between nodes in the A2B® -network
- Captures measured values with a resolution of up to 12 bits and independent of bus line status and activity
- Tests the diagnostic function of the A2B® -transmitter by inserting a short-circuit fault
- Compatible with AD240x, AD241x, AD242x, and AD2433 transceivers
- Features an external load port for simulating passive A2B® -nodes and testing phantom power
- Includes industrial-grade connectors for the A2B® -bus that are compatible with the NOFFZ Infotainment Test Device ITD 1024 or with other A2B® -bus test devices
- Can be used at any point in the A2B® -network without additional bus configuration

Advantages
Functional diversity
- Can additionally generate errors such as short circuits to a reference supply or between two lines
- Also allows load simulation via an external resistive load
Software support
- Via an intuitive application (LTB 1024 Test Panel) for commissioning and lab setup
- Via libraries for NI LabVIEW, NI TestStand, and .NET for automation
No distortion
- All simulation modes are designed with non-mechanical switches to avoid affecting the A2B® -lines during normal operation and to ensure long life without performance degradation
Various measurement setups
- Voltage and current measurement with one LTB 1024 between a master and a slave device
- Voltage and current measurement with one LTB 1024 between two slave nodes
- Monitoring of voltage and current between all nodes within an A2B® -network with multiple LTBs 1024
In this measurement configuration, the LTB 1024 is placed between a master and a slave device for current and voltage measurement, whereby the master device is simulated by the NOFFZ Infotainment Test Device ITD 1024
