Signal generators are essential test equipment for ham radio operators, used for aligning receivers, testing antenna systems, and troubleshooting transceivers. These devices produce a controlled RF signal at specific frequencies and power levels, which is critical for verifying the performance of station components and ensuring proper operation across the bands.

Hams often use signal generators to inject known signals into circuits for alignment or to measure gain and linearity. Manufacturers like Keysight (Agilent) and Tektronix offer a range of RF signal generators, from basic models for general testing to advanced units with modulation capabilities for digital modes. Operators can find both commercial and low-cost options, such as those from Windfreak Technologies or ORMELABS, to support their homebrew projects and station maintenance.
