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

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: 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: 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: 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 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...
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...
