Keithley 2400 vs Keithley 2450 SMU Digital Source Meter Difference?
Keithley SMU (Source Measurement Unit) digital source meters are precision electronic test equipment that combine current and voltage sources with measurement capabilities. These devices are designed for use in test applications where tightly coupled sources and measurements are required.The Keithley 2400 Series SMU digital sourcemeter provides four-quadrant precision voltage and current sources/loads, as well as measurement capabilities on a touch-screen user interface.
The main differences between the Keithley 2400 and 2450 are the operator interface, the measurement range and the basic accuracy. :
Operation interface: 2400 adopts pure key operation and digital tube display, while 2450 adopts touch screen operation and full-colour high-resolution touch screen interface. This makes the 2450 more intuitive and easier to use, especially for users who need to learn and use it quickly, the 2450's touch screen operation provides a better user experience.
Measurement range: The 2400 has a voltage range of 200 mV - 200 V and a current range of 1 μA - 1 A, while the 2450 has a voltage range of 20 mV - 200 V and a current range of 10 nA - 1 A. This means that the 2450 has a much wider measurement range for measuring low voltages and small currents, making it capable of meeting a wider variety of testing needs.
Basic Accuracy: Both have a basic accuracy of 0.012%, but in practice, the 2450 may provide more accurate results in some application scenarios due to the higher measurement range it supports.
Communication Interface: Although both communication interfaces support serial and GPIB communication, the 2450 does not support Ethernet communication, which is the same as the 2400. However, given the need for network communications in modern laboratory and production environments, this limitation may have an impact on usage scenarios.
Additional features: The 2450 integrates i-v characterisation, curve tracer and semiconductor analyser functions in one unit, providing a richer range of test functions. In addition, the 2450 introduces Keithley's new TriggerFlow triggering system, which allows the user to control instrument execution, similar to Development Flow Diagram 7, which provides greater flexibility and control over complex test processes.
The Keithley 2450 offers improvements and enhancements over the 2400 in terms of operator interface, measurement range, basic accuracy, and additional functionality, making it more suitable for application scenarios that require high-precision measurements and complex test processes.
What are the specific differences between the touchscreen operator interfaces?
Touch screen size and resolution: Although both use a five-inch touch screen, the Model 2450 has a higher resolution. 2450 uses a full-colour, high-resolution touch screen interface, while the Model 2400 does not explicitly mention the resolution, but only the five-inch touch screen.
User Interface Design: The Model 2450 uses an icon-based menu structure, a clean design that reduces the number of setup steps by nearly 50 per cent, replacing the cumbersome traditional push-button, multi-level menu structure. In addition, Model 2450 has built-in iconised help functions to support intuitive operation, greatly reducing the learning curve. In contrast, Model 2400 has less information, but mentions its intuitive, multi-touch user interface that enables more details to be measured, viewed and discovered.
Functional Features: Model 2450 adds context-sensitive front-panel assistance that provides real-time operating instructions and prompts. In addition, Model 2450 features a USB 2.0 memory I/O port, HELP button, rotary guide/control buttons, front/rear panel input selection buttons, and more. The specific functional features of the Model 2400 were not detailed in the information I searched for.
Programming Modes: The Model 2450 is enhanced with SCPI and TSP® script programming modes, while the Model 2400 is compatible with SCPI programming modes. This indicates that the Model 2450 offers more flexibility and enhanced features in programming.
The Keithley 2450 focuses on the touchscreen operator interface in terms of higher resolution, more advanced iconised menu structure, increased context-sensitive front-panel assistance, and enhanced programming modes compared to the 2400.
