Data acquisition 1. Siloed data
One of the biggest reasons for manufacturing data going to waste is that it often exists in siloes. As such, the current state of play within many manufacturers could be compared to the parable of “the blind men and the elephant”. In the story, six blind men each inspect an elephant from a different perspective, coming to different conclusions as to what the animal must be. One feels the trunk and believes it is a snake, while another touches a tusk and believes it is a spear. There is a similar problem within manufacturing. If data
only gives part of the picture to different people within the business, it can be hard for them to identify a specific problem or evaluate a situation. This leaves a vast amount of data elsewhere in the organisation going to waste. If data is only viewed through the lens of a specific individual or department, it can be difficult to avoid bias - and then it will not have a positive impact.
2. Conflicts leading to paralysis
Even if data siloes are broken down, there is a risk that manufacturers can become overwhelmed with too much data. These days, one single car can generate up to 25 gigabytes of data every hour - so imagine how many data points manufacturing plant could produce. Trying to evaluate and come to terms with all this data when making important decisions can easily lead to decision paralysis, with data offering conflicting guidance. This decision paralysis has proved a huge barrier to
creating autonomous vehicles - if they are unable to process information quickly enough, they sometimes end up making no decision at all. Many of us will have experienced similar problems in meetings, with time eaten up by arguing whose data is correct, rather than drilling into what the data is telling us.
A UNITED FRONT There is a simple solution to these two big problems: manufacturers need to ensure all team members and departments are able to look at the same data, and are given access to the same tools to analyse it. This is the only way to agree exactly what the most pressing problems are, and how to address them. The volume of manufacturing data is only going to
increase in the years to come, so this issue will continue to grow in importance. This is why manufacturers’ approach to data needs to be standardised and available to the relevant person in the correct context. By defining a manufacturing data architecture - as part of an operations management platform - manufacturers can capture the most useful value from the ever-escalating amount of data that is going to be stored in manufacturing systems. Manufacturers need to get a single source of truth for their data, then give employees across the organisation access to the tools they need to analyse and make sense of it. Then they can move forward confident in their ability to put data to use. This will enable them to make the most of the investments they have made in Industry 4.0, and set the organisation on course to make increasingly intelligent data-driven decisions.

ADVANCES IN MULTI- CHANNEL RF SIGNAL ACQUISITION AND GENERATION
performance instruments that are open-source and as such provide an affordable alternative to many expensive measurement and control instruments. Companies like Bosch, Apple, NASA, Siemens, HIGHVOLT and many others trust Red Pitaya’s products for their performance, versatility and ability to be customised. Now, Red Pitaya has decided to go multi-channel. Applications like medical and industrial imaging (MRI and ultrasound systems), nondestructive testing, RADAR/LIDAR, phased array antennas, readout of scientific multichannel detectors, multi-channel SDR receivers or power grid monitoring require multi-channel signal acquisition and generation solutions that can become very costly, as the price grows rapidly with each added channel. This year Red Pitaya will change this by launching two new solutions – the STEMlab 125-14 X-Channel System will enable users to adjust the number of channels required to their own needs, and a four RF Input single- board test and measurement platform that will fulfill the needs of multi-channel applications. The STEMlab 125-14 X-Channel
R
ed Pitaya has had a strong impact on the test and measurement market with its range of high-
System is designed for applications that require multiple channels for RF signal acquisition or generation. It consists of multiple STEMlab 125- 14 devices that have synchronised clocks and triggers and comes with software that supports multi- channel streaming of input and output signals from/to a client PC over a 1Gbit ethernet interface. The STEMlab 125-14 4-Input system is based on the STEMlab 125-14 model, but instead of 2 RF inputs and 2 RF output channels it
offers 4 input channels running at 125 Msps / 14bit, comes with Zynq7020 and has improved noise and cross-talk performance. The STEMlab 125-14 4-Input will be available in September 2022. Mateja Lampe, CEO comments:
“There are several medical, telecommunications and automotive applications that require multi-channel RF signal processing solutions and play a huge role in improving the quality and safety of our lives and the products we use. At Red Pitaya we believe that by providing more affordable multi-channel solutions to the market we will help researchers and industry solve such challenging problems faster and more efficiently.”
