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. Er wird neben der Automobilindustrie auch zunehmend in anderen Bereichen wie Konferenzsystemen eingesetzt. Speziell für diese A2B®-Technologie haben wir ein Leitungs-Messgerät entwickelt:
Die 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 and 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 setup, the LTB 1024 is placed between a master and a slave device to measure current and voltage,
with the master device being simulated by the NOFFZ Infotainment Test Device ITD 1024.
