Rf Measurements

Understanding RF Measurements & Specifications

This tutorial takes the attendees through some RF measurements commonly used for characterizing Wireless transmitters, receivers and RF test equipment. Specifications like EVM (Error Vector Magnitude), TOI (Third Order Intercept), VSWR (Voltage Standing Wave Ratio), Frequency response flatness, instantaneous bandwidth, bus bandwidth etc. will be discussed.

Software Defined Radio

Software Defined Radio - Flexible & Faster Radio Design Approach

Software-defined radio (SDR) is a wireless communication system where components of the wireless system like the modulation / de-modulation schemes, carrier frequency, pulse shaping & matched filtering etc. are all defined in software. This gives flexibility to the user for conducting research & teaching by implementing custom wireless communication systems. This session takes the attendees through the basics of SDR and then introduces various SDR platforms available from National Instruments to build a flexible wireless communication system.

Designing, Prototyping & Testing RF Systems for Research

Designing, Prototyping & Testing RF Systems for Research

Having a tightly integrated platform which spans from design to prototype to test, is always a 'dream come true' for any engineer, and this is especially true for RF & Wireless engineers. The NI RF platform consists of multiple software & hardware components like:
•AWR Visual Systems Simulator for simulating RF circuits
•FPGA based RF hardware for in-line RF signal processing
•VSA + VSG + VNA for RF / Wireless test
•LabVIEW software which ties all the above together
This session gives a holistic picture of the NI RF platform and how it can be used for various stages of product development like simulation, Hardware-In-Loop, Prototyping & Manufacturing Test.
