Low Noise Digitizer and Lock-in Amplifier

Zurich Instruments sets a new milestone with the Digitizer Option for the MFLI, a lock-in amplifier for the middle and low frequency range. Current and voltage signals are digitized with a sampling rate of 60 MSamples/s and a bandwidth of 7 MHz. Exceptional is the low input noise of 2.5 nV/√Hz and the 16 bit resolution (24 bit in HD-mode). The input range is adjustable from ±1 mV up ±3 V, or ±10 nA up ±10 mA, allowing a perfect adjustment to the signal amplitude. Current and voltage signals can be acquired continuously as well as triggered with a demodulated signal, a signal threshold or a pattern on the digital inputs. This so called cross-domain triggering allows new measurement approaches. The digitizer option is completely integrated into the LabOne user-interface. The instrument can be controlled from a web-browser without additional software installation, but LabOne also offers simple integration into MATLAB, LabVIEW, Python or C based programs.
Additionally the input signal can be analyzed with the integrated oscilloscope, plotter, software trigger and spectrum analyzer.
To complement the intuitive LabOne software, detailed documentation with tutorials and examples is available. Application fields for the MFLI lock-in amplifier include optical chopper applications, MEMS characterization, pump-probe experiments, ultrasonic material research as well as quantum electronic research.
