Combining a high-performance digital multimeter (DMM) and data-acquisition system with Ethernet capability, the Model 2701 delivers 6.5-digit resolution (22-bit analog-to-digital conversion) and long-distance networking. Users can set up one or more PC-controlled 2701s in a measurement system with no need to buy and install GPIB cards or software.
In fact, the 2701's built-in Web page lets users begin making measurements right out of the box, with no external software. Using Internet Explorer on the host PC, operators can enter the 2701's IP address in the URL line and immediately begin diagnostics, network configuration, and debugging.
An included TestPoint runtime program offers basic datalogging capabilities that can be customized with the TestPoint application development package. Or, users can build fully custom systems with the free IVI-style drivers (VISA based) designed for use with several common development environments. The drivers come with a number of helpful programming examples.
Standard and optional measurements include ac and dc voltage and current, digital I/O signals, temperature, frequency, period, two- and four-wire resistance, continuity, and event counting/totalization. The unit's own control logic can actuate indicators or relays and directly interface with external systems through open-collector digital I/O.
The modular instrument can hold up to 80 differential channels of multiplexed measurement and control. Channels can be scanned at up to 500 channels/scan. A 450,000-sample, nonvolatile memory stores time-stamped results during data logging without tying up the network. The industry-standard 10/100BaseTX fast Ethernet and TCP/IP protocol are built in.
The Model 2701 is available now starting at $1895.
