Signal Generators Fundamentals: Introduction to Direct Digital Synthesis
While direct digital synthesis (DDS) might sound mysterious, its implementation is quite straightforward. In this webcast, you will see exactly how DDS works. In addition, you will see how DDS-based signal generators are able to use this technology to generate phase-continuous frequency sweeps. In addition, you will see how DDS enables signal generators to achieve better than 1µHz of frequency precision.
Signal Generators Fundamentals: Scripting to Create Advanced Signals
National Instruments signal generators utilize an advanced feature known as scripting to create dynamic waveform sequences. With scripting, signal generators are able to change waveforms on the fly such that different test signals can be generated for different states of the device under test. Watch this webcast to see how scripting is implemented and understand the types of sequences that can be configured.
Signal Generators Fundamentals: Use of Filtering and Interpolation to Improve Spectral Purity
While sample-and-hold digital-to-analog converters (DACs) are able to provide accurate approximations of analog signals, they can also produce unwanted spectral images at high frequencies. In this Webcast, learn how NI signal generators utilize analog and digital filtering to eliminate hgh-frequency spectral images for a spectrally pure output.
