Good day I bought my SA ultra from Zeenko Aliexpress It was fine and passed all tests and calibration then I have only used it as a signal generator and did not upgrade (v1.4 156) While testing a

The high output can give a "start of sweep" pulse so no need to modify the HW -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I just found this interesting using the Tiny SA as a sweep generator. Good luck Using the TinySA as a sweep generator (there is a trigger output! read pinned comment below) (

Hi folks, I haven't read through this thread in detail - just skimmed it quickly.? Thought I'd mention that a spectrum analyzer set to zero span can be used as a makeshift oscilloscope.? I don't

QtTinySA from v1.0.2 can continuously save sweep data to (multiple) CSV files https://github.com/g4ixt/QtTinySA/wiki/Saving-sweep-data-continuously Ian

Hi Andy, Fair enough. I also tested a Baofeng, Quansheng & VX7R. The results were similar to yours. I don't think the Baofeng radios have much or any filtering, whereas the Quangsheng (UVK6) and VX7R

Hi to all, I decided to put a description and example results of the current status of my APP in on shared folder (anyone with a link below could explore its status). ==> I don't want to generate new

tinySA App does not display the RBW or attenuation when they are set to AUTO; perhaps they could be displayed on the status bar along the bottom. I also do not see a control nor display for

Hi Simon, Thanks for pointing us to the right answer. The command works well without any issues. Kind regards, Juan, M0WWA

Agreed. But for the sake of completeness I was actually using a 10w 1st attenuator, not a 5w as I previously stated (my typo). Actually the 10w version looks like the 5w version but just with an added

Steps are OK although?I don't understand why you would need to erase the flash memory. Other people that did need to erase? -- Designer of the tinySA For more info go to https://tinysa.org/wiki

I've tested (S21) all my attenuators (most inexpensive from Amazon) with a nanoVNA. They are all pretty flat across their stated range...

I see plenty of spurious crap around any Baofeng principle frequency even with 80 dB attenuation, and that's when putting out only 1 Watt! MEASURE>HARMONIC works fine also. A very sensitive unit the

I uploaded the shell script to Files.

Hello Erick, I was trying to update the both units today with latest tinySA4_v1.4-196-g1e9c187.bin Following your your Firmware Upgrade page I did run $ *dfu-util -a 0 -s 0x08000000:leave -D

I like your test and description, however I suggest at least a 10W 1st attenuator, should have at least double the power capability as attenuators can get hot and their resistance / attenuation can

100% agree. Thanks Erik. This is my ethos, and the how I have always advised 3rd parties. 73 de Andy

I agree. Leave out all potential failure nodes. Use more than attenuation required. The use some common sense regarding things like RBW and external attenuation and as a last resort any active

The LNA reduces the spur free dynamic range of the tinySA in exchange for lowering the noise figure. For harmonics measurements you should never enable the LNA, unless you are using a very good filter

The LNA and internal attenuator are the two components in the tinySA most prone to failure.? When the LNA is enabled, the internal attenuator is switched out and the LNA is switched in, putting the
