Spectrum\'s M4x.22xx modular PXIe Digitizers Grosshansdorf, Germany -- 1 December 2016. Spectrum GmbH has expanded its line of PXIe-based (PXI Express) high-speed digitizers with nine new cards. The new M4x.22xx series includes modules that offer one, two or four fully synchronous channels.

Each channel is equipped with its own analog-to-digital converter (ADC) with real-time signal sampling at rates from 1.25 GS/s to 5 GS/s and scope-like signal conditioning circuitry that allows programming of parameters such as input gain, signal offset and coupling.[Continue reading →]

Grosshansdorf, Germany - Spectrum is pleased to announce that it is boosting its sales and support services in the US with the opening of Spectrum Instrumentation Corporation. Spectrum, headquartered in Grosshansdorf, Germany, is a pioneer in design and manufacturing of PC based test and measurement instrumentation that is used for electronic signal capture, generation and analysis. The company specializes in high-speed digitizer and generator technology and has available over 400 modular products in the popular industry standards; PCIe, LXI and PXI.

Managing Director of Spectrum, Gisela Hassler, says: "The importance of the US market continues to grow for us, particularly with the recent release of a number of high-end digitizer products. Our US customers are generally early technology adopters and they are looking for products that give them a technical edge. Modular hardware and software products need to be backed up with good application support. One thing that really helps to facilitate this is direct access to our engineering expertise and knowledge. As such, the timing is right for us to increase our local presence."[Continue reading →]

Spectrum has announced the release of two Arbitrary Waveform Generators (AWGs) that set new standards for speed, precision and size. The single channel M4i.6630-x8 and dual channel M4i.6631-x8 AWG cards are capable of outputting electronic signals at rates of up to 1.25 Giga Samples/second (GS/s) with 16-bit vertical resolution. The combination makes these new AWGs ideal for generating high frequency signals up to 400 MHz with the best possible accuracy and fidelity.[Continue reading →]

The graph shows how the importance of thorough testing can improve the yield as products become more complex This graph shows all the measurements results of one test step with the y-axis indicating the limits extracted from the Cpk analysis above. In this example, the lower limit is 0.0000006 (0.6uF) and the upper limit is 0.0000012 (1.2uF). The spread of the measured values within the limits can be seen and any abnormalities are easily detected for immediately remedy. Heerbrugg, Switzerland - ESCATEC, one of Europe's leading providers of contract and manufacturing services, is rolling out ESCADA software across its contract manufacturing facilities. ESCADA enables the data gathered at the testing phase to be intelligently used to reduce manufacturing faults. Pioneered and developed in its central European facility in Heerbrugg, Switzerland, last year, the specially written data analysis software will be installed at ESCATEC's high volume manufacturing facilities in Malaysia in 2015.

"The ESCATEC Data Analysis (ESCADA) enables us to spot manufacturing issues much earlier and correct them," explained Thomas Eschenmoser, ESCATEC's Section Head Test Engineering. "This is a key part of our drive to catch problems early as part of our on-going programme to reduce production costs. These savings we can then pass on to customers. In addition, by having a detailed database of test results and issues, it becomes much easier to fix any problems that occur later in a product's life. As a rule of thumb, fixing an issue once a product is out in the field can cost up to hundred times more than fixing at the component level during manufacture."[Continue reading →]
