Streaming GPS Generation on the NI PXIe-5644R
www.ni.com/example/31557/en/
This sample project contains four host VIs for streaming GPS data and one FPGA VI that runs on the FPGA of the NI PXIe-5644R. Each host VI configures the GPS settings, configures t...
RF Signal Analyzer Phase Noise Calculation
www.ni.com/example/30596/en/
This example demonstrates Phase Noise calculation on a signal acquired using an NI RF Signal Analyzer. This program is a shipping example VI included with the Modulation Toolkit fo...
RF Simulation Demo: Pulse Position Modulation
www.ni.com/example/30165/en/
Theory Pulse Position Modulation may be used to transmit analog information, such as continuous speech or data. It is a system in which continuous waveforms are sampled at regular ...
RF Simulation Demo: Minimum Shift Keying
www.ni.com/example/30166/en/
Overview Minimum shift keying (MSK) modulation is a subtype of FSK modulation. MSK uses a half-cycle sinusoidal pulse, making the phase change linear and keeping side lobes low to ...
RF Simulation Demo: Filters - LPF and HPF
www.ni.com/example/30160/en/
Theory A filter is an often a frequency selective circuit that passes a specified band of frequencies and blocks or attenuates signals of frequencies outside this band. Filter may ...
RF Simulation Demo: OFDM
www.ni.com/example/30152/en/
Overview The OFDM example generates baseband complex waveform based on OFDM modulation. This is a very general tool that simulates most of OFDM systems currently in use or under de...
RF Simulation Demo: Time Division Multiplexing
www.ni.com/example/30154/en/
Overview It's often practical to combine a set of low-bit-rate streams, each with a fixed and pre-defined bit rate, into a single high-speed bit stream that can be transmitted over...
RF Simulation Demo: Sampling Theorem
www.ni.com/example/30156/en/
The sampling theorem states that, if the sampling rate in any pulse modulation system exceeds twice the maximum signal frequency, the original signal can be reconstructed in the re...
RF Hardware Example: QAM
www.ni.com/example/30155/en/
This lab is designed to examine the Quadrature Amplitude Modulation (QAM) digital modulation scheme. Fundamentally, digital modulation requires changing characteristics of the carr...
