Der Zurich Instruments UHFLI ist ein digitaler Lock-in Verstärker, der den Frequenzbereich von DC bis 600 MHz abdeckt. Er bietet eine Zeitkonstante von 30 ns für die Demodulation - was zu einer Demodulationsbandbreite von über 5 MHz führt. Dank der Kombination aus einer grossen Auswahl an verfügbaren Optionen und der Gerätesteuerungssoftware LabOne ist der UHFLI eine ausgezeichnete Wahl für Ihre experimentellen Anforderungen.

What Our Users Say

Dr. Mazin Jouda

"The UHFLI with its multi-frequency capability is essential for realizing accurate parallel EPR measurements with a high SNR and minimal circuit complexity."
