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.
- Low Noise Digitizer and Lock-in Amplifier
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.
