who need fast, reliable, and wideband RF measurements in both field and lab environments. It supports spectrum analysis, vector network analysis, cable and antenna testing, power measurements, and pulse generation in a single portable form factor. This flexibility allows you to troubleshoot, verify, and validate RF systems without carrying multiple instruments.<\/p>\n<p data-start=\"816\" data-end=\"1267\">With a frequency range from 9 kHz to 26.5 GHz, the N9918D enables accurate signal characterization across a broad set of applications. It captures hard-to-detect events with up to 120 MHz of gap-free, real-time bandwidth, helping you identify brief or intermittent interference more efficiently. The unit also supports 120 MHz wideband IQ streaming, allowing seamless integration with external analysis software for deeper signal insights.<\/p>\n<p data-start=\"1269\" data-end=\"1638\">FieldFox delivers \u00b10.1 dB spectrum measurement accuracy even without warm-up, saving time during urgent field tasks. Its bright, intuitive touchscreen simplifies navigation, file management, and data export. Weighing only 3.6 kg (8 lb), the analyzer is engineered in a durable, weather-resistant housing for consistent performance in harsh outdoor conditions.<\/p>\n<h3 data-start=\"1640\" data-end=\"1660\">Key Features<\/h3>\n<ul data-start=\"1661\" data-end=\"2204\">\n<li data-start=\"1661\" data-end=\"1742\">\n<p data-start=\"1663\" data-end=\"1742\">Covers 9 kHz to 26.5 GHz for wide-range RF and microwave signal analysis.<\/p>\n<\/li>\n<li data-start=\"1743\" data-end=\"1861\">\n<p data-start=\"1745\" data-end=\"1861\">Performs spectrum analysis, VNA measurements, cable and antenna testing, pulse generation, and power measurements.<\/p>\n<\/li>\n<li data-start=\"1862\" data-end=\"1940\">\n<p data-start=\"1864\" data-end=\"1940\">Captures transient signals with 120 MHz real-time, gap-free bandwidth.<\/p>\n<\/li>\n<li data-start=\"1941\" data-end=\"2017\">\n<p data-start=\"1943\" data-end=\"2017\">Streams wideband IQ data up to 120 MHz for advanced post-processing.<\/p>\n<\/li>\n<li data-start=\"2018\" data-end=\"2079\">\n<p data-start=\"2020\" data-end=\"2079\">Delivers high accuracy: \u00b10.1 dB without warm-up time.<\/p>\n<\/li>\n<li data-start=\"2080\" data-end=\"2145\">\n<p data-start=\"2082\" data-end=\"2145\">Lightweight, rugged, and weatherproof at 3.6 kg (8 lb).<\/p>\n<\/li>\n<li data-start=\"2146\" data-end=\"2204\">\n<p data-start=\"2148\" data-end=\"2204\">Touchscreen interface improves workflow and file access.<\/p>\n<\/li>\n<\/ul>\n<h3 data-start=\"2206\" data-end=\"2234\">Included Accessories<\/h3>\n<ul data-start=\"2235\" data-end=\"2390\">\n<li data-start=\"2235\" data-end=\"2252\">\n<p data-start=\"2237\" data-end=\"2252\">AC\/DC adapter<\/p>\n<\/li>\n<li data-start=\"2253\" data-end=\"2277\">\n<p data-start=\"2255\" data-end=\"2277\">Localized power cord<\/p>\n<\/li>\n<li data-start=\"2278\" data-end=\"2309\">\n<p data-start=\"2280\" data-end=\"2309\">Rechargeable Li-ion battery<\/p>\n<\/li>\n<li data-start=\"2310\" data-end=\"2364\">\n<p data-start=\"2312\" data-end=\"2364\">Soft carrying case with backpack + shoulder straps<\/p>\n<\/li>\n<li data-start=\"2365\" data-end=\"2390\">\n<p data-start=\"2367\" data-end=\"2390\">Quick Reference Guide<\/p>\n<\/li>\n<\/ul>\n<div class=\"tm-en-blocks\"><\/div>\n<div class=\"kx\">\n<div class=\"block\">\n<div class=\"eyebrow\">Applications<\/div>\n<h2 id=\"apps-n9918d\">What is the Keysight N9918D used for?<\/h2>\n<div class=\"cards c3\">\n<div class=\"card\">\n<div class=\"i\">\ud83c\udf92<\/div>\n<h3>Handheld RF field testing<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\ud83d\udce1<\/div>\n<h3>Base station and antenna maintenance<\/h3>\n<\/div>\n<div class=\"card\">\n<div class=\"i\">\u26a1<\/div>\n<h3>Fast multi-function measurement<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"kx\">\n<div class=\"block faq\">\n<div class=\"eyebrow\">Frequently asked questions<\/div>\n<h2 id=\"faq-n9918d\">Keysight N9918D \u2014 frequently asked questions<\/h2>\n<details>\n<summary>Where can I buy a genuine Keysight N9918D in Vietnam?<\/summary>\n<div class=\"a\">Techmaster Electronics is an authorised Keysight Technologies distributor in Vietnam.
