It operates at 4 and 6 GHz. To accelerate your work, each operating mode has a task-driven user interface that saves time in the field. Step up to FieldFox \u2013 and boost your readiness.<\/p>\n<p>The Keysight (Agilent) N9912A is mainly a cable and antenna analyzer. It can be set up with a spectrum analyzer. It can also include a 1-port vector network analyzer or a 2-port scalar network analyzer. You can order Keysight (Agilent) FieldFox with additional capabilities: power meter, independent signal generator, and interference analyzer.<\/p>\n<p><iframe title=\"\" src=\"https:\/\/www.youtube.com\/embed\/iw2MCZ3OYHU\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><br \/>\nAngetrieben von <a href=\"https:\/\/youtubeembedcode.com\">Wie man ein YouTube-Video einbettet<\/a> und <a href=\"https:\/\/starburstnotongamstop.org\/\">starburstnichtongamstop.org<\/a><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>Key features of Keysight&#8217;s FieldFox handheld RF analyzer include:<\/strong><\/h2>\n<ul>\n<li>Integrated QuickCal removes the need to carry a calibration kit into the field. It makes cable and antenna tests easier. You can trust its accuracy and repeatability with every measurement.<\/li>\n<li>FieldFox&#8217;s CalReady allows for quick calibration. This makes the unit ready for testing cables and antennas immediately after powering up or being preset.<\/li>\n<li>A task-driven user interface derived directly from standard field test procedures guides performance tasks naturally and easily.<\/li>\n<li>Unmatched sweep speed cuts down the time it takes to solve problems. Test times are over 50 percent faster than traditional RF handheld tools.<\/li>\n<li>Fast fault location with 1001-point resolution and 96-dB dynamic range in the spectrum analyzing mode.<\/li>\n<li>Versatile field usability with its lightweight (6.2 lbs.), transflective display, backlit keys, simple data transfer, and modern connectivity. The water-resistant chassis withstands wide temperature ranges and humid environments, meeting tough environmental standards (MIL-PRF-28800F).<\/li>\n<\/ul>\n<h3><strong>Measurements<\/strong><\/h3>\n<ul>\n<li>Cable and antenna analyzer for return loss, one-port cable loss, distance to fault, line sweeping, and VSWR measurements<\/li>\n<li>Handheld network analyzer (S11, S21, phase, and Smith Chart)<\/li>\n<li>Handheld spectrum analyzer, optional preamplifier<\/li>\n<\/ul>\n<div id=\"imageLeftTextRight\" class=\"row\">\n<div class=\"col-md-6 text-left my-auto p-3\">\n<h4><strong>Return loss and DTF measurements<\/strong><\/h4>\n<p><img decoding=\"async\" class=\"alignnone wp-image-3439 size-medium\" src=\"https:\/\/sonoransurplus.com\/wp-content\/uploads\/2025\/08\/Return_loss_and_DTF_measurements-533x400.png\" alt=\"Return_loss_and_DTF_measurements\" width=\"533\" height=\"400\" srcset=\"https:\/\/sonoransurplus.com\/wp-content\/uploads\/2025\/08\/Return_loss_and_DTF_measurements-533x400.png 533w, https:\/\/sonoransurplus.com\/wp-content\/uploads\/2025\/08\/Return_loss_and_DTF_measurements-768x576.png 768w, https:\/\/sonoransurplus.com\/wp-content\/uploads\/2025\/08\/Return_loss_and_DTF_measurements-1000x750.png 1000w, https:\/\/sonoransurplus.com\/wp-content\/uploads\/2025\/08\/Return_loss_and_DTF_measurements.png 1024w\" sizes=\"(max-width: 533px) 100vw, 533px\" \/><\/p>\n<div class=\"editable\">\n<p>FieldFox can make both return loss and distance-to-fault measurements at the same time.
