pushing the jog button during a long scanraw

Erik,
Pressing or moving left/right cancels the running slow "scanraw", but it would be very useful if I could also do this by sending a serial command.

Martin,
Can you check if pushing the jog button during a long scanraw will abort the scanraw?

Hi,
Attached is an image of the scope capture.

Also, please see the image of the High side as input, and the low side shows no radio signal input...
Any ideas?

Gary,

Look in the Wiki for a section "Introduction and other videos".

Hello,
I am trying to measure transmitted power(dBm) from my medical device in a RF enclosure at bluetooth frequency(2.442 GHz) using the ultra. This project will remain active for atleast 20 years and I am wondering what would be the lifetime for tinySA (in years maybe?) if i leave it connected to my PC runnning all the time on manufacturing systems.
I dont mind buying new ones as long as they will still be available and supported without going obsolete.

Thanks!

As others have stated, for manufacturing medical equipment you need an instrument that can be calibrated and a calibration certificate issued. The nearest equivalent hand held spectrum analyser, that can be calibrated to national accreditation body standards, is the TTi PSA6005, sit down¡­ the cost is around €2800 plus the cost of calibration.

I did replace the MC because it was not upgrading FW.

Since you are having such a productive run right now, I wonder if you would mind also looking at?, the uninterruptible "scanraw" command. That gets nasty when you want to terminate an extremely slow scan in a GUI that displays the spectrum - currently the only way to cancel is to switch off the tinySA.

This is a known problem for which there is currently no solution

Bob,

Send me a PM and I will give you a rather lengthy reply as to my background in R&D and pre-compliance testing.? I've too spent a lot of time running to test facilities.?

When you say, "So you still have to go to an Accredited Test Lab for the final Compliance testing." is it without going through an approved Acceptance Test first ???
I've never imagined that you wouldn't want to ATP it both before and after.? ?Exactly what compliance tests are you referring to?? ?Are you doing Internal R&D (IRAD) or are you a subcontractor with CLIN deliverables?? ?

Andy

I haven't found any irregularities working in Vpp ,Vrms, tested with 4? markers (3 of them delta between them).

What I have observed is that while we are using linear units (W, Vrms or Vpp), when manually modifying SCALE/DIV, the REF LEVEL goes from automatic to manual, almost always leaving the graph off the screen. It's not serious because the solution is to manually turn REF LEVEL into automatic mode. I report it only so that you are aware of this behavior

Hi Andy,

You are obviously not an electronics design engineer where your design has to meet compliance standards.

In a previous life I worked for a company designing and developing equipment for Australian Government agencies.
We also did some design and testing work for commercial companies.
We were an accredited Defence EMC Test lab which was recognised by the US, UK and European agencies.
But we could not certify commercial equipment! We had to go out to an accredited commercial lab for commercial certification.
But we could do all our "pre compliance" testing in house.
Needless to say, we never had a piece of commercial kit fail final commercial compliance certification!

The moral of this story is that Commercial Compliance Testing costs BIG bucks so any development and testing you can do in house will save you a lot of money.

So you test your equipment in house with a TinySA Ultra and when you think it is right, you then send it to a commercial lab for Pre-Compliance Testing.
They give you a report as to whether it will pass or fail the final Compliance Test. If it will fail, they tell you where.
You then use your TinySA Ultra to improve your product in house until it passes with a significant headroom margin.
You then resubmit for Pre-Compliance testing again. If it fails, back to the iterative process of in house improvement and testing.
If it passes, go for the Final Compliance test.

Let me assure you, you have just saved yourself an enormous amount of money using the TinySA in house.
Even if you have professional grade equipment, you do not have the requisite Accredited Compliance Test Lab Certification.
So you still have to go to an Accredited Test Lab for the final Compliance testing.

It is a brutal world out there as I am sure Dave will attest to.

Cheers...Bob VK2ZRE

Erik,
You are amazing.
Didn't anyone tell you it is Christmas and you can take a few days off!
Thank you so much for everything you do for us!
It really is VERY much appreciated.
All the very best for the Festive Season and to a wonderful 2024 New Year.
Cheers from Downunder...Bob? VK2ZRE

?Dave,? ?

?As always you are very knowledgeful and hands on with the equipment - something I've gotten away from over the past 40 years. Maybe I can pick your brain sometime if you don't mind.

As a small consulting business and a non production or as a services contractor I doubt you would be required to maintain a Quality Assurance Program.? I'm not sure if you could be subjected to an audit either.? I'm?not saying what you are doing is wrong at all.? You're?using a working standard, yup, its in the NIST /Z540 program.? If needed you could pay for the paper.

We've strayed greatly from the question on medical equipment production testing.? I think we are of mutual consensus for the most part.??

Erik, Thanks for chiming?in.? Happy Holidays all.??
Cheers Dave,??

Regards,

Andy

But the tinySA (and Ultra variant) is capable of certain professional uses, such as site survey work for radio microphones & similar, as previously noted.

Any comparatively cheap piece of equipment can be used for both ¡°professional¡± and ¡°non-professional¡± purposes. Equally, any comparatively expensive piece of equipment can be used for both ¡°professional¡± and ¡°non-professional¡± purposes.

There is a separate question as to calibration of equipment, and how long it might endure before re-calibration is required. But that applies to all electronic and mechanical devices.

Or put another way, equipment becomes ¡°professional¡± if some ¡°professional¡± person decides that it is suitable for some ¡°professional¡± purpose. That said, the most usual use of the term ¡°professional¡± is as a marketing tag. (Or on an invoice!)
