It provides two built-in ports with a maximum frequency of 44 GHz (Q band) and output power up to 4 dBm.<\/p>\n<p>Engineers optimized the Keysight N9961A spectrum analyzer to excel in a dynamic spectral environment. You may encounter measurement challenges. For example, you might need to detect a weak signal in strong conditions.<\/p>\n<p>This requires a high dynamic range. You may also need to identify small interference signals that are close together. This requires excellent phase noise performance.<\/p>\n<p>The high dynamic range (TOI &gt; +15 dBm) is impressive. The low phase noise (-111 dBc\/Hz at 10 kHz offset) is also beneficial. Additionally, the fast sweep time helps make these tasks easier.\u00a0The Keysight N9961A\u00a0spectrum analyzer also provides a full power measurement suite and complete trace and state control.<\/p>\n<p><iframe title=\"\" src=\"https:\/\/www.youtube.com\/embed\/6ymGBFnVGEM\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><br \/>\nImpulsado por <a href=\"https:\/\/youtubeembedcode.com\">C\u00f3mo incrustar un video de YouTube<\/a> y <a href=\"https:\/\/beviljaralla.se\/\">beviljaralla.se<\/a><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<h2><strong>KEYSIGHT N9961A Features:<\/strong><\/h2>\n<ul>\n<li>&#8211; Make accurate spectrum analyzer measurements (\u00b1 0.5 dB) without warmup.<\/li>\n<li>&#8211; Capture intermittent signals with 10 MHz gap-free, real-time bandwidth.<\/li>\n<li>&#8211; Characterize radar pulse profiles with a portable solution.<\/li>\n<li>&#8211; Perform over-the-air measurements for 5G TF and LTE.<\/li>\n<li>&#8211; Capture I\/Q data for RF signal monitoring and analysis.<\/li>\n<li>&#8211; Use GPS\/GNSS for geolocation and timestamping.<\/li>\n<li>&#8211; Carry one lightweight unit at 3.2 kg (7.1 lb).<\/li>\n<\/ul>\n<h3><strong>SOFTWARE DE BOLSILLO FIELDFOX<\/strong><\/h3>\n<p>Mejore las capacidades de su analizador port\u00e1til FieldFox con actualizaciones de software convenientes, dise\u00f1adas para ofrecer mediciones precisas en el campo.<\/p>\n<ul>\n<li>\u2013 Llevar un instrumento port\u00e1til que maneje el mantenimiento de rutina y la soluci\u00f3n de problemas en profundidad<\/li>\n<li>&#8211; Configure as a spectrum analyzer, built-in power meter, tracking generator, and more<\/li>\n<li>\u2013 Ordene software preinstalado o mejore un instrumento existente<\/li>\n<\/ul>\n<h3><strong>SOFTWARE ANALIZADOR DE SE\u00d1ALES VECTORIALES PATHWAVE (89600 VSA)<\/strong><\/h3>\n<ul>\n<li>\u2013 Registrar se\u00f1ales en el campo y evaluarlas posteriormente utilizando 89600 VSA<\/li>\n<li>\u2013 Demodular y realizar un an\u00e1lisis exhaustivo de se\u00f1ales vectoriales para optimizar su implementaci\u00f3n.<\/li>\n<li>\u2013 Decodifica y verifica los mensajes de las capas MAC, RLC y RRC a trav\u00e9s de m\u00faltiples tramas de radio<\/li>\n<li>\u2013 Analizar y solucionar problemas de se\u00f1ales en aplicaciones celulares, de conectividad inal\u00e1mbrica, aeroespaciales, de defensa y de prop\u00f3sito general<\/li>\n<\/ul>\n<p>With the Keysight N9961A FieldFox\u2019s InstAlign capability, internal amplitude alignments occur automatically as environmental conditions change, without any user intervention.
