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 measure-
ment capabilities of Keithley’s Model 6485 5½-digit
Picoammeter, the Model 6482 adds higher measure-
ment 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 analyz-
ing multi-channel devices, monitoring currents
in multiple locations on materials, and recording
data from multiple sensors at once. The dual chan-
nels facilitate easier control and data aggregation.
The greater channel density increases the number
of instruments (and channels) that can fit in con-
fined 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 pro-
vide 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 chan-
nels. 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.
