Description
Overview
The Keysight N9321C is a 4 GHz Basic Spectrum Analyzer (BSA) designed for engineers, technicians, and educators who need reliable RF measurements without unnecessary complexity. With frequency coverage from 9 kHz to 4 GHz, the N9321C is well-suited for wireless communications, EMI diagnostics, and general RF testing. The instrument features a 6.5-inch color display and weighs only 7.9 kg, making it suitable for both bench-top and field applications.
The analyzer delivers a minimum displayed noise level of -152 dBm at 1 GHz with preamp on, a resolution bandwidth from 10 Hz to 3 MHz, and a 2 ms non-zero span sweep speed. These specifications enable detailed signal analysis and fast troubleshooting in manufacturing, service, and educational environments.
