Capabilities and features
The Model 2450 has the following features:
• High-resolution, five-inch touch-screen display with enhanced graphical data visualization and
on-screen debug and error histories
• Reduced source noise in band (<10 Hz) and wideband (<1 MHz)
• 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 four rear-panel triaxial
connectors
• Backward compatibility with Model 2400 SCPI programs using Model 2400 emulation mode
Some additional capabilities of the Model 2450:
• 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
• SCPI and Test Script Processor (TSP
TM
) programming languages with remote interface ports
(IEEE-488/GPIB, USB, and LAN)
• Built-in math expressions and user-defined expressions (using a remote interface)
• Up to one-million-point reading buffer with seven setups (five user defaults, factory default, *RST
default) that can be stored and recalled
• Resistance and power measurement functions
• High-capacitance mode for load impedance up to 50 µF (microfarads)
• Filtering to reduce reading noise
• Overcurrent and overvoltage protection
• Safety interlock through rear-panel connector
• Trigger model supports extensive triggering and synchronization schemes at hardware speeds
• LXI
®
Core Specification 1.4 compliance
• TSP-Link
®
system expansion interface that test system builders can use to connect multiple
instruments in a master and subordinate configuration. TSP-Link is a high-speed trigger
synchronization and communication bus.; advanced Test Script Processor (TSP
®
) scripting
engine features enable parallel script execution across a network
• Supports IEEE-488 (GPIB), USB, and ethernet local area network (LAN) connections
