Rohde & Schwarz FSEB30 20Hz – 7GHz Spectrum Analyzer

The Rohde & Schwarz FSEB30 is a spectrum analyzer covering 20 Hz to 7 GHz, designed for general-purpose RF measurements and advanced digital communication system testing. It delivers measurement speeds up to 25 sweeps per second with a quasi-analog refresh rate, supported by a high-speed synthesizer achieving 5 ms full-span sweeps. The instrument features an ultra-wide dynamic range of 115 dB intermodulation-free performance, a large 24 cm TFT display with 500-pixel resolution, and flexible sweep capabilities from 1 µs to 16000 s depending on span configuration.
