MF-DIG Digitizer

Combining the MFLI Lock-in Amplifier or the MFIA Impedance Analyzer with a digitizer opens up a wide range of measurement opportunities thanks to continuous streaming, cross-domain triggering, and a segmented memory. The 2 Scope channels can simultaneously display signals from the differential voltage input and from the current input. The integration afforded by LabOne® enables direct control through the web interface and straightforward programming with any of the LabOne APIs.

MF-DIG Functional Diagram

Low-noise digitizer for voltage and current signals

The MFLI Lock-in Amplifier and the MFIA Impedance Analyzer combine high-performance, low-noise input stages for voltage and current signals with common digitizer features such as shot and continuous operation. The input ranges can be adjusted to optimally match the input signals.

Thanks to the digitizer functions of the MF-DIG Digitizer option, input signals can be monitored and measured before demodulation and subsequently analyzed in the time and frequency domain. With this option, the LabOne Scope is transformed from a debugging tool into a fully featured digitizer. Two digitizing channels can measure two signals simultaneously.

The MF-DIG Digitizer option provides a current signal digitizer offered by no other vendor in the market today.

High-resolution sampling

For experiments that require sampling rates significantly below 60 MSa/s, the HD24 high-definition mode improves the physical 16-bit vertical resolution by averaging consecutive samples. Depending on the number of averaged samples, the nominal resolution can become as high as 24 bits.
