This webinar, the first of the RF Fundamentals Webinar series covers the fundamentals of RF & Wireless Communication Systems. It deals with questions like :
• What is RF? Why operate at higher frequencies? What is frequency mixing?
• What is modulation? - AM, FM, PSK, QAM etc.
• Architecture of a Vector Signal Generator & Analyzer
• What is I/Q representation of an RF signal?
• General architecture of a digital communication system
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 (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.
In this session, learn how FPGA technology can be combined with RF instruments for implementing high throughput test, prototyping and in-line signal processing. Some example applications like channel emulation, frequency domain triggering, power amplifier testing, digital pre-distortion etc. will be discussed.
As the Wireless standards become more advanced, so do the test setups to test these wireless devices. Attend this session to know the basics of WLAN physical layer measurements and how to speed up WLAN device test by orders of magnitude. The session also takes you through the additional requirements of a MIMO test setup which is required for testing 802.11 n & ac standards. FPGA based RF instruments which make the testing of WLAN devices over a simulated channel possible will also be discussed.
Testing cellular power amplifiers requires a suite of instrumentation and poses unique considerations. With over 1 billion mobile phones sold per year, many with multiple PAs per part, lowering test times to increase throughput is becoming increasingly critical. This session will provide an overview for both hardware and software solutions available from National Instruments to address cellular PA test.
This webcast introduces common GPS receiver tests including sensitivity, Time To First Fix, position and tracking accuracy. It demonstrates an innovative way of bringing GPS signals into the lab for comprehensive GPS test using a hybrid of simulated signal generation as well as real-world signal record and playback.
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.
