Siglent SSA5085A, Spectrum Analyzer, 9 kHz–26.5 GHz, Multi-Touch 12.1″ Display

The Siglent SSA5085A is a high-performance spectrum analyzer with a frequency range spanning from 9 kHz to 26.5 GHz. It features a large 12.1-inch multi-touch display and supports real-time spectrum analysis with up to 40 MHz of instantaneous bandwidth (with optional upgrade). The instrument offers deep measurement capabilities including channel power, ACPR, OBW, harmonics, TOI, and both analog and vector digital modulation analysis. With a displayed average noise level of –165 dBm/Hz and phase noise of –105 dBc/Hz at 1 GHz (10 kHz offset), it's well-suited for broadcast, communications, IoT, and EMI applications. Remote control is provided via LAN web interface or USB, and the analyzer supports numerous software options through a modular licensing system.
