The compact RTSA7500 Real-Time Spectrum Analyzer is a powerful, full-featured spectrum analyzer designed to analyze wireless signals in real-time (not progressively scanned). This is essential for seeing intermittent and frequency-hopped signals. The RTSA7500 has all the standard features of a sophisticated, expensive bench-top spectrum analyzer, but at far lower cost since it uses the display and processing power of an attached PC. Frequency controls, marker functions for tracking specific frequencies and multi-trace functionality are all included, as well as a real-time triggering for measuring complex data signals such as Wi-Fi and LTE. Sophisticated FPGA-based digital signal processing within the RTSA7500 enables the capture of elusive time-varying signals across an instantaneous bandwidth of up to 100MHz.
