特性和优点

灵活的通道配置

根据需求配置所需精度

不同测量任务对精度和带宽的需求各不相同。LMG600 系列提供 S、A、B、C 四种通道类型,可在同一主机内灵活搭配。其中,S 通道支持 0.015% 交流测量精度和 10 MHz 带宽,C 通道则适合低频测量应用。您可以根据应用需求灵活配置仪器,避免规格冗余,同时确保关键测量环节满足性能要求。

双路径架构

单次测量同时采集宽带和窄带数据

传统功率分析仪往往无法兼顾抗混叠保护和宽带信号保真:启用抗混叠滤波器会损失宽带信号信息,禁用滤波器则可能导致 FFT 分析出现混叠误差。LMG600 系列通过每个通道配置两个独立的模数转换器,解决了这一难题——一路采集未经滤波的宽带信号,另一路采集经过抗混叠滤波处理后的窄带信号。两条路径并行工作,可基于同一输入信号同时提供 RMS 值、谐波和 FFT 分析结果。

自定义菜单

用户界面满足具体的应用要求

根据具体应用需求自定义视图:选择需要显示的电气参数和 I/O 变量,在屏幕上自由布局,并添加接线图、照片或品牌标识等图形元素。 通过/失败指示器以及用于输入 DUT 特定参数的输入字段均可直接嵌入视图中,从而打造直观易用的测量环境,即使经验较少的操作人员也能轻松上手。

即插即测的传感器集成

扩展电流测量范围

连接的精密电流传感器 (PCT) 通过集成总线向 LMG600 发送信息,自动传输缩放因子、延迟补偿参数、传感器类型以及上次校准日期等数据。LMG600 系列功率分析仪还可直接为传感器供电,无需配置独立电源。直接测量和基于传感器的测量结果保持一致,无需手动微调即可获得准确结果。

使用 LMG 测试套件进行一致性测试

端到端标准合规性评估

LMG 测试套件可引导 LMG600 按照以下标准完成 EMC 一致性测试: - IEC/EN 61000-3-2/-12(谐波) - IEC/EN 61000-3-3/-11(闪烁) - EN 50564/IEC 62301(待机功率) 测试套件支持在线和离线运行,可与符合标准要求的交流电源配合使用,并导出包含完整可追溯信息的测试报告。相关标准若有更新,也会在颁布后及时纳入测试套件。

过程信号接口 (PSI)

机械和环境数据实现精准同步

可选的 PSI 提供快速模拟输入、开关输入和输出、转矩/转速/频率输入以及 32 路模拟输出,所有信号均与功率通道实现同步。可在测量电压和电流的同时采集转矩、转速、温度和压力等参数。外部设备可根据测量值直接触发或控制。

多设备同步

突破七通道限制

多台 LMG600 可通过同步电缆连接,构成一台虚拟功率分析仪,并自动实现测量周期、系统时间、瞬态触发事件以及能量积分状态的同步。即使扩展至八个或更多通道,所有主机之间的测量结果始终保持一致,无需人工进行数据对齐。

全动态范围无缝测量

覆盖从微安到 32 A 的电流测量范围,无需切换量程

IEC 62301 和 EN 50564 标准合规性测试要求在各种负载条件下对被测设备进行连续监测。LMG600 系列提供 500 µA 至 32 A、3 mV 至 1000 V 的连续动态范围,以及 18 位分辨率和最短 10 ms 的测量周期。通过一次不中断运行,即可完成待机和满载状态的特性表征,并在接近量程下限时仍保持 0.015% 的基本精度。
