Documentazione

L'UHFLI di Zurich Instruments è un amplificatore lock-in digitale che copre la gamma di frequenze da DC a 600 MHz. Esso offre una costante di tempo (30 ns) per la demodulazione - risultante in una larghezza di banda di demodulazione che supera i 5 MHz. Grazie ad una ampia scelta di opzioni disponibili ed il software di controllo dello strumento LabOne, l'UHFLI rappresenta una scelta eccellente per le vostre esigenze sperimentali.

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."
