The Keysight N9322C is a basic spectrum analyzer covering 9 kHz to 7 GHz, positioned around budget-conscious performance, efficiency, and simplicity. It performs both swept and FFT spectrum analysis with 1 Hz frequency resolution, and its capabilities can be tailored through a range of licensed options that extend the base instrument into modulation analysis, cable and antenna test, and precompliance roles.
A spectrum analyzer measures the amplitude of signals across a range of frequencies, letting an engineer see the spectral content of a signal rather than its time-domain waveform. The N9322C supports general spectrum analysis along with a power suite for channel power, ACPR, and occupied bandwidth (via the task planner), AM/FM and ASK/FSK modulation analysis, multi-channel scanning, a spectrogram spectrum monitor, and reflection and distance-to-fault measurement for cable and antenna work when the corresponding options are installed.
ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we list are equipment we keep on hand.
Keysight Technologies traces its test-and-measurement heritage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was then established as the independent Keysight Technologies in 2014, the name under which this analyzer is produced.

Important: Maximum input ratings: ±50 VDC and ≤ +33 dBm average continuous power (3 minutes maximum, input attenuator ≥ 20 dB, 2 MHz to 7 GHz).
Important: Several measurement capabilities are not part of the base analyzer and require specific options: the tracking generator requires Option TG7; reflection measurement requires Option RM7 (which itself requires Option TG7); CISPR-compliant EMI bandwidths and the quasi-peak detector require Option EMC; the precision frequency reference is Option PFR; and the GPIB interface requires Option G01.
Important: The analyzer meets its specifications only when within its calibration cycle, after at least 30 minutes warm-up, and after being stored at an ambient temperature within the allowed operating range for at least two hours before turn-on (per the datasheet's definitions and conditions).
Recommended pairing: with Option PWM installed, the N9322C supports the Keysight U2000 Series USB power sensor, and Option PWP adds support for the Keysight U2020 and U2042/44 X-Series USB peak and average power sensors.
