Fig. 2 The Agilent analyzer plot of a ham radio antenna in real time. Using a return loss bridge, I can see a VSWR picture of what the load looks like at the frequency of interest and nearby ...

Army researchers built the sensor, which can sample the radio-frequency spectrum — from zero frequency up to 20 GHz — and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.

Fortunately, dual-purpose analyzers that combine spectrum analysis and VNA are available now, which are designed with a mix ...
