This User?s Guide provides an introduction to the 8510C Network Analyzer, showing how the instrument is used to characterize the frequency and time domain performance of network components. Rather than being a formal text on measurement theory and techniques, this guide is intended to help you get hands-on experience with the network analyzer, using example procedures to illustrate network analyzer operating sequences in actual measurement situations. This helps you to get started making network measurements using the 8510 and demonstrates the ease with which accurate results can be obtained.
