The Agilent N9342C is a handheld spectrum analyzer (HSA) covering a frequency range of 100 kHz to 7 GHz, tunable down to 9 kHz, on an AC-coupled, 50 Ω Type-N input. Built for field use, it pairs benchtop measurement performance with a rugged, portable form factor: a 6.5 in (170 mm) TFT color display at 640 × 480 resolution, a weight of 3.2 kg, and battery operation, so the instrument can be carried into the environments where signals actually live.
Designed to make field measurements easier, the N9342C operates across a -10 to +50 °C temperature range and runs up to four hours on a fully charged battery, suiting it to routine field testing where bench instruments cannot go. Through its option set it extends into cable and antenna test, channel scanning, AM/FM and ASK/FSK modulation analysis, time-gated spectrum analysis, and high-accuracy power measurement, letting a single handheld cover a broad span of field tasks.
ValueTronics stocks and holds its own inventory in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned instrument is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer, so buyers get the right instrument in the condition they expect, backed by people who know the equipment.
The Agilent name traces to Hewlett-Packard, whose test and measurement business was spun off as Agilent Technologies in 1999. Agilent's electronic measurement division was subsequently established as Keysight Technologies in 2014.

Important: Maximum safe input level: +33 dBm average continuous power (3 minutes maximum, input attenuator setting ≥ 20 dB, 2 MHz to 7 GHz) and ±50 VDC maximum.
Important: High accuracy power measurement (Option PWM) requires an Agilent U2000 Series USB power sensor; frequency range (9 kHz to 24 GHz) and dynamic range (-60 to +44 dBm) are sensor dependent.
Important: Option GPS uses a built-in GPS antenna; an external GPS antenna (N934xC-GPA) is offered as an optional accessory and is connected via the SMA-F external GPS antenna connector.
Important: Specifications apply to temperatures ranging from -10 to 50 °C unless otherwise noted, and require the analyzer to be within its calibration cycle and turned on at least 30 minutes.
Recommended pairing: the optional high-accuracy power measurement capability supports the Agilent U2000 Series USB power sensor for power measurements from 9 kHz to 24 GHz.
