NI 9225 3通道, 300 Vrms模拟输入模块

NI 9225 C系列模拟输入模块具有300 Vrms总体测量范围,以实现高压测量应用,如:电源测量、电能质量监控、电机测试、电池组测试、燃料电池测试。用户执行的瞬态和谐波分析,具有每通道高达50 kS/s的高速同步采样速率。此外,用户可阻止接地回路,提升系统安全,因为3条NI 9225通道之间具有600 Vrms通道间隔离。

如需在高电压环境下使用或者添加信号线防应变,请试用NI 9971后壳套件。单独出售的NI 9971,包含4个后壳。替代或备用连接器可纳入NI 9976套件单独出售;NI 9976套件包含NI 9225中使用的10个2孔(2-position)螺栓端子。

Simultaneous Sampling

Simultaneous Sampling

A property of a measurement system in which each input or output channel is digitized or updated at the same instant. You will need simultaneous sampling for applications where the time relationship between inputs is important, such as phase analysis of AC signals.


Because channel-dedicated analog-to-digital converters (ADCs) are used to sample data simultaneously between inputs, the maximum sample rate is applicable to each channel and is not divided by the total number of channels. Devices that don’t have simultaneous sampling capabilities use multiplexing to connect each channel to its ADC.


Interval scanning is a low-cost option to simulate simultaneous sampling for low-frequency signals such as temperature or pressure. This method scans the input channels at one interval and uses a second interval to determine the time before repeating the scan. The input channels are scanned within microseconds, creating the effect of simultaneously sampling the input channels.
