National Instruments at European Microwave Week 2019

I’m mike elliott from electronic specifier and i am here at Euorpean microwave week with Chris Behnke from National Instruments Chris could you just talk us through some of the options national instruments has for the aerospace and defence sector yes absolutely so, national instruments has actually been involved in the aerospace and defence sector for quite some time and we deal with solutions in both the mechanical structural test all the way to RS spectrum in this booth today we actually showing quite a few of our RS instrumentation options partially our vector signal transceiver this product is combining the generation capability, analysis capability of traditional box instruments into a single instrument with FPGA back end capability for custom DSB processing and what that enables is the testing at the parametric level and the system validation level of common mission critical applications such as radar satellite communications and electronic welfare so very hot topics in the aerospace and defence industry and due to the software define nature we can actually adapt to these mission critical applications as they change over time so cognitive radar or wide band width satellite communications so do you also do hardware in the loop testing we definitely do yea one of the nice things about having both analysis and generation capability on our instrumentation as well as the DSB on the back end is that we can actually close the loop in a hardware fashion in a real time perspective both in RF test applications as well as physical test applications so another example where we often use hardware on a loop testing is for electrical mechanical test of say turbine engines in aerospace aerospace applications looking at, obviously you can offer customers the technology what sort of benefits do they get in terms of generally about their business in maybe saving time and money and getting the product to market yes absolutely, so one of the main goals of National Instruments solutions is to do all those things right. make the cost go down make test time faster as well as make the correlation process from design to validation to production, a much more compact process, partially with smaller teams yep, so because we can actually dis-changed the application capability of our instrumentation as well as the configuration via the modules quality PXI we can actually evolve our test solutions with the application in an efficient manner and i guess finally because you’re working on the next generation solutions as well here to bring to the industry in coming years yea, so absolutely, we’re tracking a lot of the industries I’m partially looking at a lot of the RF applications so satellite communications which we actually have a talk today in the defence space forum is an interesting area thats actually emerging a lot of the energy and influence of 5G with the traditional orbital satellite networks so challenges such as wide band width, high through put, integration of components of technology are all in volume we’re talking about constellation in the hundreds and thousands right these are all new challenges that the satellite industry has to adopt and national instruments are trying to track those trends and have ideal solutions for those as well okay, Chris, thank you very much for your time, appreciate it hi this is mike elliott from electronic specifier at european microwave week I’m with David Hall from National Instruments david, just like to talk a little bit about 5G new radio test challenges with higher frequencies, narrow band width just tell us a little about how national instruments are helping customers over come their testing challenges yea theres a lot of different challenges, i think you know, theres- the fact that 5G is going into millimeter wave specifically introduces new challenges you know, one of the things about millimeter wave is the propagation because of the propagation you have new technology like beam forming that are essential to get the signal power over the distance you need so beam forming introduces over the air challenges we’re actually showing a demonstration today where we take a actually device and you can rotate it across two axis to see the beam pattern and how that changes across, how the device moves ok, and you been working with chip manufacturers and other partners, could you just talk a little about that as well yes, so the reality is a lot of our customers are solving some of these challenges for the first time just as we are we’ve been wireless for a long time and if you go back 10 years it was pretty forepart to do an over the air measurement because theres certain in-certainties that are involved with over the air which you tried to stay away from so if we spend a lot of time educating people on how to be able to do a conductive measurement now when you get to antenna package technology its not possible anymore so we have to remove some of those in-certainties in an over the air so a lot of that is hands on with our customers helping them understand some of the challenges are and of course how to address them I mean i missed all this we’re looking at the FR2 band width which are obviously a higher frequency we still got the FR 1 in action i guess around LTE there’s still a place for that in national instruments propersions as well yea, so one of the things we’ve observed over the last 12 to- 12 months or so has been a massive deployment of a lot of the FR 1 5G infrastructure and so the challenges with testing a lot of the FR 1 devices are really evolutionary in nature, i mean you go to 3.5GHz devices thats a little bit wider frequency you know sure there’s some challenges like DBD get a little bit harder familiarising a part but in terms of the calibrating and fixturing and the types of measurements you do and they way you make those, they are actually fairly similar certainly we have a lot of solutions for sub 6 GHz 5G testing and we’ve been actively deploying them over the last 12 months but the challenges are actually much more manageable than what we see with FR 2 so what kind of solutions do you offer then to be clear yea, so we have a couple different solutions so in the lab a lot of customers will use vector signal transceiver product line and that will be used for automated validation or characterisation of parts we have customers that will do a huge sequences of test across temperature, band and different band combinations they want to see every possible scenario for how that part can operate and how its going to perform, so they’ll use an instrument for that ok and then just looking further ahead we’re moving, inevitably we’ll move to higher frequencies as 5G becomes more and more what sort of work is national instruments doing now to meet the challenges that might come in 2 to 5 years time yes so there’s really a couple different aspects to that one of them is monitoring which bands are going to get adopted because there is a lot potential bands that could be used, whether or not the infrastructure gets deployed there is still a question and kind of a decision from the carriers so one of the things we’re very actively monitoring is actually the 6 to 9Ghz band as well theres some new studies from the FCC in united states on potentially using those for mobile communications so those are the bands we’re actively watching to see if theres some development there okay that’s terrific thank you very much david
