2182A/E

Keithley 2182A 毫微伏电压计此双通道 2182A 专门适用于进行稳定、低噪声电压测量以及进行可靠且重复的低阻抗材料特性描述。 它可提高测量速度，且相对备选低电压测量解决方案，可提供更佳的噪声性能。 广泛的响应时间选择便于优化速度/噪声权衡。 广泛的有用响应时间确保了低噪音级别，通常是 1s 响应时间为 15nV p-p 噪声，60ms 则为 40-50nV p-p 噪声。Delta 模式坐标测量可逆电流源高达 24Hz，并通常带有 30nV p-p 噪声（一个读数），可平均多个读数以显著降低噪声 线路同步提供 110dB NMRR，最大程度减少交流电共模式电流的影响 电阻测量范围：0Ω → 1MΩ 温度测量范围：-200 → +1820°c 双通道支持测量电压、温度或未知电阻与参考电阻器之间的比率 内置热电偶线性化以及冷接点补偿 ### 随附2107-4 低热输入电缆 1.2m 4ft 带有铲形接线片、用户手册、服务手册、触点清洗剂、线芯以及鳄鱼夹### Keithley

The two-channel Model 2182A Nanovoltmeter is optimised for making stable, low noise voltage measurements and for characterising low resistance materials and devices reliably and repeatedly. It provides higher measurement speed and significantly better noise performance than alternative low voltage measurement solutions. The Model 2182A represents the next step forward in nano voltmeter technology, replacing the original Model 2182 and offering enhanced capabilities including pulse capability, lower measurement noise, faster current reversals, and a simplified delta mode for making resistance measurements in combination with a reversing current source,

.

Make low noise measurements at high speeds

.

Delta mode coordinates measurements with a reversing current source

.

Synchronisation to line provides 110dB NMRR and minimises the effect of AC common-mode currents

.

Dual channels support measuring voltage, temperature, or the ratio of an unknown resistance
