When choosing an RF instrument, it is easy to get lost in the many specifications that vendors use to characterise an instrument's performance. Moreover, in a world where wireless technologies are ever changing, engineers with little RF experience commonly design and test RF devices and components.

This tutorial explains both basic and advanced RF instrument specifications. Specifications covered include real-time bandwidth, frequency range, tuning speed, phase noise, and voltage standing wave ratio (VSWR). Many of these specifications apply to more than just instruments. In fact, all RF devices are subject to the same design rules as RF instrumentation. Thus, the design details and trade-offs are applicable to a variety of RF devices.
