I'm develloping systems based on ucontrollers and a variety of wireless devices. The wireless devices have a CE end FCC marking, if I have a device with only a ucontroller I can do the CE marking myself. But if I combine the ucontroller and wireless I need testing (Europe/Netherlands).
My question is: can I do this testing myself and what type of equipment do I need?

I would like to know about instruments for measurment and testing of smps .
For development of smps which instruments i have to purchase for test lab.
thank a lot ,
for responding ,i am interested in
testing instrument set up for smps development and analysis lab,
will you guide and
recommend test instruments ?
I am the creator of the ExactCharge Refrigeration Calculator which is available for SmartPhones, iPhone, and Windows based computers. I would like to create a stand alone calculator of my software for distribution in hvac supply houses but don't know where to start to begin to develop the calculator prototype perhaps using Arduino. We currently have the ability for SI scale so we could distribute the product Wordwide.The ExactCharge Calculator has been available for 6 years and is well appreciated by those who own it. Ritchie Engineering has a stand alone PT device but it does not have near the functionality of the ExactCharge Calculator software. I was hoping you might be able to point me in the right direction. You can view my product at www.exactcharge.com to help gain a better understanding of its abilities. A stand alone version should sell well and have a good profit margin. Any help would be greatly appreciated.
I'd suggest starting with Tektronix "Power Supply Measurement and Analysis Primer". You should be able to dwnload it from: http://www2.tek.com/cmswpt/tidetails.lotr?ct=TI&cs=Primer&ci=14468&lc=EN
Hope that helps!
Hi Jim, What is the recomended method for checking fuses in a 3 phase motor circuit?
Thanks for your time
Can you help me find the where to download the lastest firmware upgrade for a Tenma oscilloscope 72-8225 (40MHz, 2 channels). I try to find the firmware on the web but no luck till now.
Thank you very much.
Please find attached link for software for Tenma 72-8225, if you have any further enquiry, please send me email firstname.lastname@example.org
Its been a while since using an oscilloscope and I got myself loop:i.e. the question might sound a bit daft.
I want to visualise the voltage waveforms on an induction motor and controller. Now, to measure the individual phases I would have a connect the probe to 1 or more of the phases but what do I choose as a ground? Would that be the negative of the DC input?
You have a few options, each with pros & cons:
1) Use a differential probe to measure across each phase.
2) Use a scope with isolated channels. Several handheld models offer that capability, plus the Tektronix TPS2000 series instruments.
3) Measure each phase relative to ground and use maths function on the scope, or offline ona PC) to derive the phase measurements.
In any case DON'T cut your scope's ground lead and float the instrument - it's dangerous and violates numerous safety standards.
Tektronix have an application note on making floating measurements. You can download it from: http://www.tek.com/Measurement/App_Notes/3M_17773/eng/3MW_17773_0.pdf
I have to implement the 10MHz reference signal project for our measurement devices.
I would like to know if Tektronix does have GPS disciplined Rubidium oscillator devices + antenna + surge protection + redundancy option
I am sorry, Tektronix do not have GPS disciplined oscillator devices and I have checked in Farnell range as well with other our supplier.
Thank you for enquiry.
Tektronix offer a line of frequency counter/timers - the & MCA3000 - but not the Rubidium oscillator devices you are seeking.
