Signal Studio for Real-time Fading N7605C

Technical Overview

– Apply real-time fading on signals for receiver test and access flexible configurations for all fading parameters

– Select from different fading types, including Rayleigh, Rician, Suzuki, log normal, pure Doppler, and constant phase to simulate different propagation environments

– Use pre-configured setups for many communication standards including LTE, WLAN, W-CDMA, cdma2000®

– Add AWGN (Option 403 on N5172B EXG/N5182B MXG X-Series signal generators) with calibrated S/N to the signals

– Accelerate the signal creation process with a user interface based on parameterized signal configuration and tree-style navigation

Introduction  

A fading channel emulator allows engineers to comprehensively evaluate wireless communication systems by predicting their performance in response to real-world conditions. Signal Studio for real-time fading software (N7605C) paired with an EXG (N5172B) or MXG (N5182B) 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  

N7605C 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. Pre-configured fading profiles simplify initial setup, or you can choose user−defined fading profiles to meet your specific test needs.

– Conformance test under fading conditions of receivers, during RF/baseband integration and system verification

– Verifications of the baseband subsystems, in the process of chip design and integrated circuit development

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 N7605C can support the following fading types:

– Rayleigh − small−scale multipath scattering

– Rician − Rayleigh with a direct ray

– Log normal – large-scale free-space path loss

– Suzuki − Rayleigh with log normal

– Pure Doppler − frequency shift due to motion
