Hệ thống sourcemeter để bàn Keithley 6482 Dual Channel

Hệ thống sourcemeter để bàn Keithley 6482 Dual Channel Picoammeter/Voltage Source (120V line power voltage)

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.

Programmable Limits and Filters

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.

Ratio and Delta Measurements

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.

Features that Expand Test and Measurement Flexibility

Scaled voltage analog output. The Model 6482 can transmit measurement results to devices such as DMMs, data acquisition boards, oscilloscopes, or strip chart recorders.
220V overload protection. With this high overload protection and a robust design, the Model 6482 can withstand abusive overflows.
One-touch front panel design. Functions can be configured easily with the push of a button without complicated function menus.
Built-in Trigger Link interface. The Trigger Link interface simplifies synchronizing the Model 6482 with other instruments and voltage sources and combines six independent selectable trigger lines on a single connector for simple, direct control over all instruments in a system.
RS-232 and IEEE-488 interfaces. These interfaces make it easy to integrate the Model 6482 into automated test and measurement systems.
Display on/off switch. For research on light-sensitive components, such as measuring the dark currents of photodiodes, the front panel display can be switched off to avoid introducing light that could significantly reduce the accuracy of the results.
REL and LOG functions. The Model 6482 can make relative readings with respect to a baseline value or display the logarithm of the absolute value of the measured current.
Rear panel triax inputs. Triax inputs ensure premium noise protection. Triax-to-BNC adapters, which are included, allow inexpensive, easy-to-use BNC cables to be employed in situations where noise is less of a concern.
