什么​是​PXI​数字​万​用​表?

PXI​数字​万​用​表​(DMM)​可​执行​高​精度​电压、​电流、​电阻、​温度、​电感、​电容​和​频率/​周期​测量​以及​二极管​测试。

InstrumentStudio™​交互​式​软件

PXI DMMs are shipped with an interactive soft front panel called InstrumentStudio for ready-​to-​run configuration and measurements. You can configure the instrument and view instantaneous measurements in a small panel or even plot measurements over time in a large panel.

最​精准​的​7.5​位​数字​万​用表

With 26 bits of resolution and high-​stability, metrology-​class measurements that range from 10 nV to 1,000 V, 1 pA to 3 A, and 10 µΩ to 5 GΩ, the PXIe-4081 outperforms traditional box DMMs.

可​自​定义​的​测量​设置

NI DMMs give you the ability to fully customize measurement settings to prioritize speed or accuracy by programmatically adjusting ADC calibration, auto-​zero, settling time, and aperture time using the NI-​DMM device driver API.

隔离​数字​化​仪​模式

With excellent measurement quality, NI DMMs combine the functionality of a traditional DMM and an isolated, high-​voltage (1,000 V) digitizer mode with sample rates up to 1.8 MS/​s​—​36X faster than traditional DMMs (50 kS/​s).

与​PXI​开关​同步

Combine PXI DMMs with a wide selection of PXI switches to cost-​effectively scale the number of channels. Hardware handshaking removes the overhead of software timing and bus communication, resulting in faster test times and the highest measurement throughput.
