Signal Studio for Real-time Fading
N7605B
Technical Overview
Introduction
A fading channel emulator allows engineers to comprehensively evaluate wireless communication systems by predicting their performance in response to real-world conditions. The Keysight N7605B Signal Studio for real-time fading software together with an N5172B EXG/N5182B MXG vector signal generator provides a comprehensive diagnostic toolset for designing and verifying wireless signal processing devices. This solution applies real-time fading to a baseband signal in a single general-purpose signal generator.
Receiver test in dynamic environments for early R&D and performance verification
N7605B Signal Studio for real-time fading software is a powerful tool for verifying your cellular communications, WLAN, digital video/audio, or satellite/military communication receiver designs. Use this software to fade your digital baseband signals and apply AWGN, and to convert the faded and noisy signals to RF frequencies in the N5172B EXG/ N5182B MXG vector signal generator. Preconfigured fading profiles simplify initial setup, or you can choose user−defined fading profiles to meet your specific test needs.
Top Features
Powerful support on different fading types
The ability to simulate different fading profiles is essential for evaluating receiver performance in a variety of environments. The N7605B can support the following fading types:
Flexible configuration on different Doppler spectrum shapes
Doppler spectrum shape is another important part to simulate different fading scenarios. The N7605B supports the following Doppler spectrum shapes, enabling you to simulate the environments required for the test.
Predefined fading profile setups
Predefined setups for common wireless and digital video formats are included with the software to simplify test preparation. You can modify these standard profiles to provide custom configurations for simulating specific environments.
Add AWGN with ease and accuracy
Add noise on the faded signals easily on the N7605B. You can set the signal to-noise ratio, carrier bandwidth, noise bandwidth and many other parameters on the user interface of the software.
Key Specifications
Simulate real-world conditions to test multi-format receivers more quickly and validate design robustness earlier in the development cycle with the EXG/MXG signal generator.
