Attached, please find the response curve for a low pass filter generated by my TinySA Ultra and my new noise source. The curve was generated using TinySA-App. Thanks again to all who helped me

Lawrance, Because for the tests I feed it a calibrated level from my calibrated HP signal generator and read the output with the TinySA. If I feed it a -50dbm signal the output equals a -50dbm signal

First, thank you both (Kenneth Greenough & John Cunliffe W7ZQ ( /g/tinysa/profile/4088509 ) ). How are you sure the dbm is equivalent to dbm out? larry

Thanks Kenneth, Nice descriptions of the fundamental. This particular up converter uses an external 10Mhz oscillator that ideally should be synchronized to the spectrum analyzer for best accuracy. It

Mike, I agree with all of Jim's suggestions and have only one to add of my own: Try googling "MA Gunnplexer" to find more "threads to pull" for info on the subject of devices of this type. I don't

Hello Larry, An up converter is basically a mixer,double balanced being best for the purpose and an oscillator.? For stability the oscillator will likely be a crystal controlled one.? Say the osc'

This helps. Bug found and will be solved in next release -- For more info on the tinySA go to https://tinysa.org/wiki/

I have this problem too. Mirek Dne 21.12.2022 v 15:33 Erik Kaashoek napsal(a):

Can you post a screen capture or photo? I can't replicate -- For more info on the tinySA go to https://tinysa.org/wiki/

Thanks for the update.?? I am only seeing a partial readout of the freq. Example 482.3100 shows 2.310MHZ Is that what I should be expecting to see or should I see the entire freq ie 482.310MHZ Rich

If ignorance were bliss, I'd be in heaven. ?I'm not there yet but I am ignorant. What is an 'up converter'? ?Yes, I understand the words but that does not tell me what it is nor how it works.

Bumped version to v1.4 -- For more info on the tinySA go to https://tinysa.org/wiki/

Roger, Thanks for the info...seems to be working fine. This is my first experience working with a wideband noise source and I purchased it just for the educational value. -- Ed, K0KC k0kc@...

When programming on a Windows computer, I found that the new fw is written correctly if I physically remove the USB cable after programming, not just turn off the OFF switch on the TinySA ULTRA. Mike

Lane, Good work! One remark: with Erik's reorganisation / renaming V4.3 to main the "git checkout V4.3" isn't needed anymore, after the clone you're already on the right branch. So the section about

Strange, it was done with verification, all errorless ... Now changed USB port, same results. Funy because 1st update few days ago on to? version 556 was without problems.

Maybe the upgrade did not happen? -- For more info on the tinySA go to https://tinysa.org/wiki/

Any idea why mine SA Ultra after upgrading to the latest still displays version "tinySA4_v1.3-556-g9825888" ? Mike

This is an Ultra-only feature, but the code compiles also for the "tiny" tinySA. So you version number junkies , get it there:
