双通道 2182A 型纳伏表最适合进行稳定的低噪声电压测量，以及适合可靠且重复地检定低阻材料和器件。 相比其他低电压测量解决方案，其测量速度更快，噪声性能显著提高。 它提供简化的增量模式，适用于结合反向电流源（如 6220 或 6221 型号）进行电阻测量。
特点：
1nV 灵敏度
1s 响应时间下的噪声通常只有 15nVp-p，60ms 下噪声为 40–50nV p-p
双通道
测量周期与电源线交流周期同步
内置热电偶线性化和冷接点补偿
内部极性反转测量技术
最适合用于 6220/6221 型电流源
与 6220 或 6221 结合使用时，支持增量模式电流反向测量技术
2182A/6221 组合将信号脉冲与测量同步
The dual-channel 2182A nanovoltmeter is most suitable for stable low-noise voltage measurement, as well as for reliable and repeatable verification of low-resistance materials and devices. Compared with other low-voltage measurement solutions, its measurement speed is faster and the noise performance is significantly improved. It provides a simplified incremental mode, suitable for resistance measurement in combination with a reverse current source (such as 6220 or 6221 models).
Features:
1nV sensitivity
The noise under 1s response time is usually only 15nVp-p, and the noise under 60ms is 40-50nVp-p
Dual channel
The measurement cycle is synchronized with the AC cycle of the power line
Built-in thermocouple linearization and cold junction compensation
Internal polarity reversal measurement technology
Most suitable for 6220/6221 current source
When combined with 6220 or 6221, it supports incremental mode current reverse measurement technology
The 2182A/6221 combination synchronizes the signal pulse with the measurement
