The N9321C from Keysight is a Basic Spectrum Analyzer (BSA) that operates from 9 kHz to 4 GHz. It has an analysis bandwidth of up to 1 MHz, a phase noise of -90 dBc/Hz (@10 kHz offset), and a DANL of -152 dBm (@1 GHz). This BSA is built to address essential applications and offers proven test efficiency, best-in-class usability, and flexibility to adapt to new requirements. It is equipped with a tracking generator and a built-in VSWR bridge for transmission and reflection tests. This spectrum analyzer identifies interfering signals from unwanted or unexpected transmissions with a powerful spectrum monitoring feature. It supports AM/FM/ASK/FSK demodulation analysis suites for Internet of Things transmitter characterization.
The N9321C enables users to automatically implement up to 20 predefined measurements and reduce test setup time by 95% with the task planner feature. It provides straightforward and efficient operation with marker demodulation, one-button optimization, and user-definable soft keys. This BSA includes a window limit feature that makes simultaneous determinations on the frequency and power limits of a signal. This one-button pass/fail determination reduces instrument setup complexity and significantly improves testing efficiency.
This basic spectrum analyzer includes a display with a resolution of 640 x 480 pixels along with RJ-45, USB, and IEEE-488 interfaces. It is available in a benchtop enclosure that measures 132.5 x 320.0 x 400.0 with N-type (female) connectors.
