The Tektronix RSA518A is a USB-connected real-time spectrum analyzer delivering 9 kHz to 18.0 GHz frequency coverage with 40 MHz acquisition bandwidth. This portable instrument captures transient signals, hunts interference, and performs modulation analysis across 27 types including QAM, QPSK, FSK, and APSK. DPX Spectrum/Spectrogram processing enables real-time visualization of signal behavior. The analyzer achieves 70 dBc spurious-free dynamic range and intercepts signals as brief as 15 µs with 100% probability. Full-span sweeps execute at 70 GHz/sec. Purpose-built for RF troubleshooting, spectrum management, and EMC/EMI pre-compliance testing with CISPR detectors and standards-based limit lines.
