MF-DIG デジタイザ​​

MF-DIG デジタイザ

デジタイザをMFLI ロックインアンプに組合わせることにより、測定の自由度を拡張し、連続的ストリーミング、クロスドメイントリガー、メモリーセグメント化を可能にします。また、電圧入力、電流入力といった異なる入力波形をスコープ上に同時に表示できます。LabOne との組合わせにより、WEB インターフェイス(WEB ブラウザ)からの制御や、LabOne API を使用したプログラミングによる制御など、利便性が高まります。

Low-noise digitizer for voltage and current signals

The MFLI lock-in amplifier combines high-performance scientific-grade 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 over a wide range in order to optimally match the input signals.

Using the digitizer functions of the MF-DIG Digitizer option, input signals can be monitored and measured before demodulation, with subsequent analysis in both 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 are enabled to measure two signals simultaneously.

The MF-DIG option provides a unique current signal digitizer available from 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 enables an enhancement of the physical 16 bit vertical resolution by averaging of consecutive samples. Depending on the number of consecutive samples that are averaged, the nominal resolution can be as high as 24 bits.
