Building a Useful RF Test Lab on a Real-World Budget
You don't need a million-dollar anechoic chamber to do credible RF work. Here's what we actually use day to day.
A common myth is that meaningful RF work requires a fully outfitted EMC chamber and seven-figure test equipment. It doesn't. Here's the practical lab we run in Fort Mill and why each piece earns its place.
Spectrum and Vector Analysis
A modern 6 GHz spectrum analyzer with reasonable phase noise and a tracking generator covers 90% of work for sub-6 systems. Pair it with a calibrated VNA for any work involving impedance matching, filter tuning, or cable assembly verification.
Signal Generation
A vector signal generator capable of producing standards-compliant LTE/5G NR/P25 waveforms is invaluable for receiver testing. Used gear from Keysight or R&S keeps cost manageable.
Cable & Antenna Validation
A field-portable cable/antenna analyzer (Bird Site Hawk, Anritsu Site Master) is non-negotiable. Every connector and every cable run gets validated before it's energized.
Shielded Enclosures
A small shielded enclosure beats an empty room for repeatable measurements on devices under test. We use it constantly for receiver sensitivity work and emissions pre-screens.
What We Don't Have (and Don't Need)
A full anechoic chamber. For pattern measurements that require it, we partner with a regional facility. The capital cost of owning one is rarely justified for a consultancy.
