Engineering begins at the bench.
This is the W6DSR home laboratory—a working collection of professional RF, microwave, frequency, and general-purpose test equipment used to design, build, measure, and document the projects collected here.

The measurement bench
Built to see what a radio signal is really doing.
The bench brings together spectrum and network analyzers, precision signal generators, noise-figure measurement, frequency counting, laboratory power, digital multimeters, oscilloscopes, and GPS-disciplined time and frequency standards.
- Spectrum analysis
- Network analysis
- Signal generation
- Frequency standards
- RF measurement
