Capabilities and features
The Model 2461 has the following features:
• High-resolution, five-inch touchscreen display with enhanced graphical data visualization and
on-screen debug and error histories
• Voltage source noise for 10 Hz to 20 MHz (RMS) is < 4.5 mV typical into a resistive load
• True high-current source up to 7 A (10 A pulse)
• 1 A, 4 A, 5 A, and 7 A ranges
• Ability to produce individual pulses or pulse trains
• Contact check function to prevent measurement errors due to excessive resistance in test leads
when making Kelvin measurements
• High-speed source and measure digitizing
• Ability to perform sensitive measurements on low-level signals
• Higher V-sense levels, easier 4-wire configuration, and better four-point probing performance
than earlier models
• Expanded voltage, current, and resistance measurement ranges
• Simplified trigger model with source and memory configuration lists
• Front-panel USB-A connector for flash drive support; rear-panel USB-B connector for
communication, control, and data transfer
• Five front-panel banana jacks, front-panel safety earth ground, and a rear-panel screw-terminal
connector
Some additional capabilities of the Model 2461:
• Source-measure sweep capabilities (linear and logarithmic staircase sweeps)
• Four-quadrant source and sink operation
• Limit testing with a built-in comparator for pass/fail testing
• Digital I/O for stand-alone binning operations or interface to a component handler
