Technical Overviews

Leading the Industry in High-Performance System Test

Introduction

A new standard for modular system DMMs

The L4411A 6½ digit high perfor­mance DMM expands the Keysight Technologies, Inc. industry leading offering of LXI system products. 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.

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.

System integration

When deciding on your next system DMM you can’t go wrong with the L4411A. Choose from LAN (LXI), USB or GPIB interfaces, all standard on the L4411A, to connect to your computer. The 1U size is perfect for space con­strained applications like aerospace/defense depot test. Concerned about the viability of your existing software programs? This new DMM responds to standard 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. Keysight’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.

Companion LXI switch modules

Need a switch to route your signal to the L4411A? Consider Keysight’s LXI switch modules. Choose from a 40-channel armature relay multiplexer (L4421A), a dual/quad 4x8 reed relay matrix (L4433A) or a 32-channel Form A/C general purpose relay switch module (L4437A). Additionally, Keysight has LXI DAC, digital I/O and multi-function modules to help complete your test system require­ments. All from the leader in LXI instrumentation, Keysight.

Built to last

Our new DMM was designed to high standards of ruggedness and reliabil­ity. From the robust, compact package to careful selection of components and conservative circuit design, this meter is built to last. Calculated mean time between failure (MTBF) is in excess of 100,000 hours. Backed by a worldwide network of service centers, you can buy with confidence.
