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 \/>\nAngetrieben von <a href=\"https:\/\/youtubeembedcode.com\">So betten Sie ein YouTube-Video ein<\/a> und <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>FIELDFOX HANDHELD SOFTWARE<\/strong><\/h3>\n<p>Erweitern Sie die F\u00e4higkeiten Ihres FieldFox Handheld-Analysators mit praktischen Software-Upgrades \u2013 entwickelt f\u00fcr pr\u00e4zise Messungen im Feld.<\/p>\n<ul>\n<li>\u2013 Tragen Sie ein tragbares Instrument, das regelm\u00e4\u00dfige Wartungsarbeiten und detaillierte Fehlerbehebungen durchf\u00fchrt<\/li>\n<li>&#8211; Configure as a spectrum analyzer, built-in power meter, tracking generator, and more<\/li>\n<li>\u2013 Software vorinstallieren oder ein vorhandenes Instrument aufr\u00fcsten<\/li>\n<\/ul>\n<h3><strong>PATHWAVE VEKTOR-SIGNALANALYSESOFTWARE (89600 VSA)<\/strong><\/h3>\n<ul>\n<li>\u2013 Signale im Feld aufzeichnen und sp\u00e4ter mit dem 89600 VSA auswerten<\/li>\n<li>\u2013 Demodulieren und umfassende Vektorsignalanalysen durchf\u00fchren, um Ihre Bereitstellung zu optimieren.<\/li>\n<li>\u2013 MAC-, RLC- und RRC-Schichtnachrichten \u00fcber mehrere Funkrahmen dekodieren und verifizieren<\/li>\n<li>\u2013 Analyse und Fehlerbehebung von Signalen in Mobilfunk-, Drahtlosverbindungs-, Luftfahrt-, Verteidigungs- und Allzweckanwendungen<\/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.
