Analyser watches 110-MHz spectrum in real time.

by Graham Prophet

Tektronix has updated its range of RSA (real-time spectrum-analyser) instruments with the RSA6100A series. The instruments follow the approach of their predecessors in that they capture a complete wideband signal sample, repetitively, and perform high-speed transforms on each sample to yield a stream of spectrum-analysis "snapshots", allowing the user to track and measure dynamic spectral characteristics of an RF signal. In the 6100A models, the captured bandwidth extends to 110 MHz (with 73 dB spurious-free dynamic range), and the update rate
