F9860400A Channel Studio TDL Modeling Tool

TDL Channel Modeling Tool (TDL Tool) is a comprehensive application for creating custom fading models. The generated models can be used in a broad range of applications, including cellular wireless communications, defense, broadcasting, and general-purpose communication link and receiver testing. All the fundamental fading profile parameters are available in a simple and intuitive user interface. The TDL Tool is fast, easy-to-use, and supports several Keysight product platforms.

Modern communication receivers need to detect, and process received signals under various conditions, including different signal levels, propagation conditions, and interference. The performance and robustness of the communication link against multipath fading, Doppler, delay spread, and interference are fundamental system-level properties. The more critical the consequences of a potential link failure, the more important it is to carefully design and verify the system against the conditions it is intended to operate in.

Key Features

• TDL Tool supports custom channel model creating with user defined Tapped Delay Line (TDL) model definitions
• MIMO models with selectable correlation properties. MIMO based on multiple antennas and channels between the antennas, The propagation channels must be uncorrelated for the spatial multiplexing to provide MIMO gain
• Export / store created models to target instrument folder for easy usage in instrument SW
• Supports integration to test plans and automated batch generation of channel model profiles

Various telecom standards define baseline channel models for testing that the radio system or receiver performance is at acceptable level. While these standard models may be good starting point, they usually are not sufficient for R&D purposes or isolating any fading related performance issue. Standard models are made for only a limited number of scenarios, and they are often too generic for validating design-specific metrics.

The Channel Studio TDL Tool enables engineers to precisely set propagation parameters according to test requirements and optimize the verification plan to meet product specifications. Whether the requirement for testing a receiver is to validate key performance indicators or to explore "What if" scenarios, the TDL Tool helps to create the necessary channel models for the purpose.
