The Rohde & Schwarz FSEM30 is a high-performance spectrum analyzer covering 20 Hz to 26.5 GHz, engineered for signal analysis, EMC testing, component characterization, and interference detection. It delivers exceptional measurement speed with a quasi-analog refresh rate of 25 sweeps/s and full-span sweep capability in 150 ms. The instrument analyzes both analog and digital modulated signals—AM, FM, PM, BPSK, QPSK, π/4-DQPSK, 8PSK, QAM, MSK, GMSK, and 2FSK—making it suitable for advanced digital communication system testing.
