Special Project: Receive a Spectrum Analyzer and Demonstrate EMI debugging, low power design, or IoT Application

FPC1500I have been talking to one of our valued test equipment suppliers, Rohde&Schwarz, and they would like to sponsor some special projects using its FPC Spectrum Analyzers. The participants would get an FPC1500FPC1500. Each participant would need to demonstrate one of the following tasks using the product:

 

  • EMI debugging a switched-mode power supply
  • EMC pre-compliance testing
  • IOT: testing BluetoothRegistered Low Energy (BLE) transmit signals
  • IOT: Antenna matching in IoT and low power devices

 

We have roadtested these products in the past:

3GHz Spectrum Analyzer - R&SRegistered FPC1000

FPC1500 Spectrum Analyzer

 

Roadtests are open product reviews where the roadtester decides on how to roadtest the product. This special project is more application/task-focused. R&S would like to see element14 demonstrate the FPC1500's capabilities in the areas above (my bullet points). Here's the applications page for more information: https://www.rohde-schwarz.com/us/application/fpc/

 

These products are expensive. So, the participants will be required to provide me a proposal or complete an application similar to what I would do for a roadtest or a design challenge. I would like to see what you would like to do with it. Moreover, what other gear or resources you would need. This last point is important. We would like to get a better idea of what materials, resources, equipment you would need, as appropriate.

 

 

Are you Interested? Please vote in the Poll.

 

What Would You need besides the Spectrum Analyzer? Please leave a comment describing your set up.

 

Do you have any (better) ideas on how to do this special project? Please leave a comment.

 

At this point, I am still brainstorming on how I will do this special project. R&S is very interested. Any other feedback you can provide is welcome.

 

 

Randall

    Hi Miguel. I was not given the model and options. If you want to suggest what you need/like, I will earmark them. At this point, I think we have not firmed up what range of projects we want the participants…

    Here are a couple of pics of the TEM cell. It starts off at 50MHz or so with SWR = 1.4 and it rises to 3 at about 650MHz - which I expect will be the upper limit of it's usefullness. That's a 45cm ruler…

    This project is indeed very interesting. Would the expected outcome be similar to an app note or other reference document? I would target either the EMI debugging of a switch-mode power supply or EMC pre…

    Hi Randall,

    Thank you for the update.

    Is there a chance to talk with the sponsor? Because I have the PFC1500.

    As I mentioned last 5 month ago, I just need this equipment:

    - Probe set for H near-field emission measurements 30 MHz to 3 GHz, R&S HZ-17, Order No. 1339.4141.02

    - EMI emissions test software, R&S ELEMI-E, Order No. 5601.0030.02

      (This software can be downloaded; or this software can we get it via DVD; I have downloaded the actual version)

    - ELEKTRA license dongle,  EMCPC, Order No. 5601.0018K02

    - Cable set for FPC to HM6050-2, USB and RF, R&S FPC-Z1, Order No. 1328.7444.02

    - Line impedance stabilization network (LISN) HM6050-2DE, 9 kHz to 30 MHz (CISPR16), max. 16 A (DE version, safety plug, 230 V) , Order No. 3593.0351K0

      (the main power here in Austria is 230V / 50Hz)

    HM6050 V-Zweileiter-Netznachbildung | Übersicht | Rohde & Schwarz (rohde-schwarz.com)

    - Calibration kit FSH-Z29, Type N, 50 Ohm, male, Order No: 1300.7510.03

    (This is for calibration, so that I can test cables that I need for the measurement setup. I also plan to test the supply cables.)

     

    I have the other necessary parts for the test setup.

    The application is to test a SM power supply like this as described in this brochure:

    © Rohde & Schwarz; EMI debugging a switched-mode power supply with R&S®FPC1000/R&S®FPC1500 (rohde-schwarz.com)

    Best Regards

    An update....

    I previously announced which proposal the sponsor wanted to support. About a month ago, it was my understanding that they were going to ship out the equipment to me. I hadn't received it, so I contacted them last week. I learned there is a stocking/inventory issue and the lead time is long. The only immediate option they gave me was to provide a loaner unit. I said, no. So, I had to put this project on hold. I want to thank everyone who proposed a project.

    To All,

    It's been awhile since I replied because I've been talking to the sponsor about all your ideas and I have been waiting on their decision. It was quite a bit of back and forth with the sponsor (both myself and my boss). They made their decision a few weeks again and I am waiting on the equipment to arrive so I can ship it out. 

    I gave the sponsor all the ideas in the comments. What equipment you would need was included with your proposed idea. 

    They decided on a BLE Transmit testing project by ralphjy.

    What happened with this in the end? As it's gone quiet, I assume that maybe R&S decided not to go ahead.

    Test GaN Quick Mobile Charger Different CMC #1 Introduction to the experiment

    I have got the chance of experiment with Inductors, here is proposed test in my application.

    I can make further test on spectrum analysis on the GaN quick charger, removing the copper shields.

    This link  https://www.rohde-schwarz.com/us/applications/emi-debugging-a-switched-mode-power-supply-with-r-s-fpc1000-r-s-fpc1500-ap… give useful information.

    I thing I can follow the guidance on EMI debugging a switched-mode power supply .
