Die Tektronix Spektrumanalysatoren der RSA500 Serie wurden entwickelt, um Spektrumverantwortlichen, Störungssuchern und Netzwerkverantwortlichen, die Störquellen ausfindig machen, HF-Netze betriebsfähig halten und ihre Aktivitäten nachweisen müssen, die Lösung von Problemen mithilfe der Echtzeit-Spektrumanalyse zu erleichtern.
Das Kernstück des Systems ist ein USB-HF-Spektrumanalysator, der auch unter rauen Umgebungsbedingungen Bandbreiten von 40 MHz sehr genau erfasst. Bei einem Dynamikbereich von 70 dB und einer Frequenzobergrenze von bis zu 18 GHz können Sie alle interessierenden Signale untersuchen und den Messergebnissen absolut vertrauen.
Dank des USB-Formfaktors müssen Sie kein schweres Gerät mehr halten, sondern lediglich einen leichten Windows-Tablet- oder -Notebook-Computer. Einen leichten PC anstelle eines schweren Spektrumanalysators in der Hand zu halten bedeutet, dass Sie sich längerer Zeit schneller bewegen und Ihre Arbeit schneller erledigen können.
Der optionale Mitlaufgenerator ermöglicht Verstärkungs- und Verlustmessungen zur schnellen Überprüfung von Filtern, Duplexern und anderen Netzkomponenten. Und Sie können nach Bedarf Kabel- und Antennenmessungen von Stehwellenverhältnis, Reflexionsdämpfung, Entfernung bis zum Defekt und Kabelverlust vornehmen.
Produktmerkmale:
großer Frequenzbereich von 9 kHz bis 18 GHz für eine breite Palette von Analyseanforderungen
40 MHz Erfassungsbandbreite ermöglicht die Echtzeitanalyse zur Erfassung von Transienten und zur Vektoranalyse
GPS/GLONASS/Beidou-Standardempfänger zur Kartendarstellung
optionaler Mitlaufgenerator für Gewinn-/Verlust-, Antennen- und Kabelmessungen
Streaming-Erfassung kann zur Aufzeichnung und Wiedergabe von Langzeitereignissen verwendet werden
Umgebungs-, Stoß- und Schwingungsspezikationen gemäß MIL-STD-28800 Klasse 2 für den Einsatz unter rauen Bedingungen
integrierter Akku zur Verlängerung der Nutzungszeit vor Ort
Die SignalVu-PC-Software bietet eine Echtzeit-Signalverarbeitung mit DPX-Spektrum/Spektrogramm, sodass Sie die Zeit zur Suche nach transienten und anderen Störungen auf ein Minimum beschränken können.
Eine Mindestsignaldauer von 100 μs führt zu einer Erfassungswahrscheinlichkeit von 100 %, sodass Sie Probleme bereits bei der ersten Signalerfassung erkennen.
