Tektronix RSA5103B Real-Time Spectrum Analyzer

Overview

The Tektronix RSA5103B real-time spectrum analyzer combines outstanding RF performance with comprehensive analysis capabilities for everyday spectrum analysis tasks. With up to 3,125,000 real-time spectrums per second and wideband acquisition up to 165 MHz, it detects signals as brief as 0.434 μs with 100% probability of intercept. The instrument delivers dynamic range of +17 dBm TOI and -157 dBm/Hz DANL at 2 GHz, with full preselection and image-free performance across all acquisition bandwidths.
