For the test system integrator looking for the next generation modular DMM, this new meter offers the industry’s best measurement speed and throughput, a reduced size (1 rack unit high), superior measurement performance, and a choice of computer interfaces, including LXI, providing high performance, easy to use, economical I/O. A simple display, including ‘latest reading’ and LAN address, allows the system integrator to quickly integrate and debug the test system. And finally, the DMM comes with a compatibility mode, requiring little-to-no code change to upgrade your test system with next generation capabilities. Dramatic system performance Whether it’s raw reading speed or fast system throughput, the L4411A sets a new benchmark in performance. Using a new A/D technology, the L4411A achieves an impressive 50,000 readings a second at 4½ digits, and can stream readings to your computer at this same speed! Transactional I/O (single reading— measurement and PC transfer time) is 3x faster than other popular modular DMMs, significantly enhancing your test throughput. Triggering is fast and precise, with both trigger latency and trigger jitter less than 1 µs, while bus query response is less than 500 µs. ACV measurements are faster as well thanks to a digital measurement technique that additionally improves accuracy at high and low frequencies. LXI—Class C LAN Extensions for Instruments (LXI) provides the next generation I/O for system applications requiring high throughput. Transfer rates of over 250,000 readings/sec are attainable ensuring even the most data intensive measurements are fast, without the overhead cost of an instrument mainframe. LXI provides a built-in Graphical Web Interface that allows you to interactively control the DMM without the hassle of programming, making it great for debugging your system. The L4411A DMM is LXI — Class C compliant. commands for programmable instrumentation (SCPI). Additionally there is a 34401A/E1412A emulation mode to ensure the easiest upgrade possible, virtually eliminating costly software and documentation changes. The autoranging power supply allows you to connect to any input power without selecting input voltages or changing fuses. Agilent’s I/O Library Suite ships with the L4411A to help you quickly establish an error-free connection between your PC and instrument. It provides robust instrument control and works with the software development environment you choose. DMM dimensions (mm) 212.3 363.2 Enhanced measurement capabilities The L4411A offers temperature and capacitance capabilities in addition to those measurements you have come to expect such as DCV, ACV, DCI, ACI, 2-wire and 4-wire resistance, frequency, period and diode test. You also get offset compensated Ohms, allowing you to accurately measure resistance in the presence of voltages. Measurement ranges have been expanded as well; for example, DC and AC current ranges now go down to 100 µA, resulting in 100 pA resolution. Real-time math and statistics are included, and a peak-detect capability allows you to capture peaks as short as 20 µs. Companion LXI switch modules Need a switch to route your signal to the L4411A?
