6482型双通道皮安表/电压源提供两个独立的皮安表/电压源通道，用于需要双通道测量的各种低电平测量应用。6482型建立在吉时利6485型5½位皮安表的可靠测量能力的基础上，增加了更高的测量分辨率，第二个测量通道以及两个独立的30V偏置电压源。
凭借其双通道测量功能，6482型是用于分析多通道设备，监视材料上多个位置的电流以及一次记录来自多个传感器的数据的出色测量工具。双通道简化了控制和数据聚合。较大的通道密度会增加可在狭窄空间中放置的仪器（和通道）的数量。
与大多数吉时利仪器一样，可以对6482型的电流和电压限值进行编程，以确保在关键点（例如测试开始）期间保护设备。这些仪器还提供了平均值和中值滤波器，可将其应用于缓冲存储器中存储的数据
6482型可以在两个完全隔离的通道之间提供比率或增量测量。可以通过前面板或GPIB界面访问这些功能。对于具有多个检测器的测试设置，此功能可实现目标控制功能。
The Model 6482 Dual-Channel Picoammeter/Voltage Source provides two independent picoammeter/ voltage source channels for a wide range of low-level measurement applications that require dual-channel measurements. Building off of the proven measurement capabilities of Keithley’s Model 6485 5½-digit Picoammeter, the Model 6482 adds higher measurement resolution, a second measurement channel, and dual, independent 30V voltage bias sources.
With its dual channel measurement capabilities, the Model 6482 is a great measurement tool for analyzing multi-channel devices, monitoring currents in multiple locations on materials, and recording data from multiple sensors at once. The dual channels facilitate easier control and data aggregation. The greater channel density increases the number of instruments (and channels) that can fit in confined spaces.
As with most Keithley instruments, the Model 6482’s current and voltage limits can be programmed to ensure device protection during critical points, such as start of test. These instruments also provide average and median filters, which can be applied to the data stored in the buffer memory
The Model 6482 can provide ratio or delta measurements between the two completely isolated channels. These functions can be accessed via either the front panel or the GPIB interface. For test setups with multiple detectors, this capability enables targeted control capabilities.
