The acquisition and analysis of electronic signals in remote locations has become easy thanks to the release of a new option for Spectrum's Ethernet-based digitiser products. The Embedded Server option, DN2.xxx-Emb, can be ordered with any of the company's digitizerNETBOX series of LXI instruments. It effectively turns them into PC-based data acquisition units that can operate independently or, when connected to a LAN, as parts of a larger system.

The digitizerNETBOX family, with more than 30 different models, offers the widest choice of LXI-based data acquisition capabilities. Units are available with sampling rates from 200KS/s up to 5GS/s, resolutions of 8, 14 and 16 bit, bandwidths up to 1.5GHz and from 2 to 16 fully synchronous channels. The units are normally controlled via Ethernet, however, installing the Embedded Server option allows fully independent operation. The Embedded Server option combines a powerful CPU, a freely accessible SSD, more memory and a remote software development access method using standard Linux remote shell (ssh).

This enables an open platform where the user can run their own software while, at the same time, being still be connected via LAN for remote access. For example, with the option installed, the user could run a programme to acquire and analyse electronic signals in a fully automated process. Then, whenever required, the user can choose to transfer just the information (waveform data or calculated results) that are needed in a client-server based software process.

This capability makes the digitizerNETBOX suitable for data logging and surveillance applications where signals are needed to be monitored over long periods of time. The units can work autonomously collecting and analysing data for hours or even days on end. The results can be stored on the internal SSD and then, whenever needed, the important information can be accessed via Ethernet. The digitizerNETBOX can even be setup to send notification emails or alerts over the LAN, or offload stored data as soon as it is connected again to the network.

The DN2.xxx-Emb Embedded Server option is available with immediate delivery. The digitizerNETBOX series products are shipped factory tested with Spectrum's SBench 6 Professional version software, support drivers for most popular programming languages and a two year manufacturer's warranty.
