NI PXIe-4140是一款高通道数、高速源测量单元（SMU）；它的每个PXI
Express插槽均具有4路完全相同的SMU通道。每个SMU提供四象限操作，针对±100 mA时在±10
V范围内的漏极或源极电压；每路通道具有集成的遥感（4线）功能来实现精确测量。为帮助缩减测量时间和捕捉瞬态设备特性，每个SMU均具有达600,000
S/s的采样率。此外，达15,000 S/s的源测量率，可实现待测设备的快速I-V特性记述。
针对高通道应用，您能将17个NI
PXIe-4140模块装入单个19英寸、4U
PXI机箱，以便提供总共68路SMU通道。高速编列引擎允许所有这些SMU与其他各类SMU同步，或与其他仪器（如：开关或高速数字测试模块）同步。

T-clock Capability A patent-pending method for synchronization developed by NI whereby another
signal-clock domain is employed to enable alignment of sample clocks and the
distribution and reception of triggers. The synchronization of these triggers
can be implemented down to pico-seconds. | 是
