# Agilent N9342C 100 kHz to 7 GHz Handheld Spectrum Analyzer (Pre-Owned) # Agilent N9342C 100 kHz to 7 GHz Handheld Spectrum Analyzer (Pre-Owned) ## Key Features At A Glance - 100 kHz to 7 GHz frequency range, tunable down to 9 kHz (AC coupled) - Field-ready handheld operating from -10 to +50 °C; 3.2 kg with a 6.5 in TFT color display - Displayed average noise level to -142 dBm with preamp off (specified measurement conditions apply) - Resolution bandwidth from 10 Hz to 3 MHz in a 1-3-10 sequence - LAN (RJ-45, 10Base-T), USB host, and USB device interfaces standard - Up to 4 hours of battery operating time on a fully charged battery - Optional tracking generator, RF preamplifier, cable & antenna test, modulation analysis, and GPS - Optional task planner automates test setup and reporting, reducing setup time by 95% 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. ## Brand Heritage 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. ## Product Core & Specifications Specification Value Frequency Frequency range 100 kHz to 7 GHz (tunable to 9 kHz), AC coupled Internal 10 MHz frequency reference - aging rate ± 1 ppm/year Internal 10 MHz frequency reference - temperature stability ± 1 ppm (referenced to frequency reading at 25 °C, temperature varied at max. 2 °C per minute) Frequency readout marker resolution (frequency span)/(sweep points - 1) Frequency readout uncertainty ± (frequency indication × frequency reference uncertainty + 1% × span + 20% × resolution bandwidth + marker resolution + 1 Hz) Marker frequency counter - resolution 1 Hz Marker frequency counter - accuracy ± (marker frequency × frequency reference uncertainty + counter resolution) Frequency span - range 0 Hz (zero span), 100 Hz to 7 GHz Frequency span - resolution 1 Hz Frequency span - accuracy ± (0.22% × span + span/(sweep points - 1)) SSB Phase Noise (Nominal, center frequency 500 MHz, 20 to 30 °C) 30 kHz offset < -86 dBc/Hz, typical -89 dBc/Hz 100 kHz offset < -97 dBc/Hz, typical -99 dBc/Hz 1 MHz offset < -115 dBc/Hz, typical -119 dBc/Hz Resolution Bandwidth (RBW) \-3 dB bandwidth 10 Hz to 3 MHz (1-3-10 sequence) Accuracy ± 5%, RBW = 10 Hz to 1 MHz;
