6482
Dual-Channel Picoammeter/
Voltage Source
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
measurementsꢀ 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 sourcesꢀ
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 onceꢀ The dual chan-
nels facilitate easier control and data aggregationꢀ
The greater channel density increases the number
of instruments (and channels) that can fit in con-
fined spacesꢀ
Programmable ꢂimits and ꢄilters
• Dual-channel, 6½-digit
measurement capability
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 testꢀ These instruments also pro-
vide average and median filters, which can be applied to the data stored in the buffer memoryꢀ
• Dual 30V bias sources
ꢃatio and Delta Measurements
• Measure currents up to 20mꢀ
The Model 6482 can provide ratio or delta measurements between the two completely isolated chan-
nelsꢀ These functions can be accessed via either the front panel or the GPIB interfaceꢀ For test setups
with multiple detectors, this capability enables targeted control capabilitiesꢀ
• Measure currents with 1fꢀ
resolution
• 0–10V analog output for high
resolution measurement
feedback
ꢄeatures that Expand Test and Measurement ꢄlexibility
• Scaled voltage analog output. The Model 6482 can transmit measurement results to devices such
as DMMs, data acquisition boards, oscilloscopes, or strip chart recordersꢀ
• ꢁupports assembly process,
final testing, parts binning, and
specification
• 220V overload protection. With this high overload protection and a robust design, the Model
6482 can withstand abusive overflowsꢀ
• One-touch front panel design. Functions can be configured easily with the push of a button -
• 3000-point buffer memory
on each channel allows data
transfer after test completion
without complicated function menusꢀ
• 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 systemꢀ
• Trigger ꢂink for binning and
sweep test operations
• RS-232 and IEEE-488 interfaces. These interfaces make it easy to integrate the Model 6482 into
automated test and measurement systemsꢀ
• IEEE-488 and ꢃꢁ-232 interfaces
• 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 resultsꢀ
ꢀPPꢂICꢀTIꢅNꢁ
• Manufacturing component test
• Dual diode testing
• 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 currentꢀ
• ꢁemiconductor component
testing
• Rear panel triax inputs. Triax inputs ensure premium noise protectionꢀ 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 concernꢀ
• Multi-pin component testing
• Ion beam monitoring
• Electron microscopy
