I did this earlier with the help of nanovna, I used 3 harmonics

For those who do not have a specific source to generate 5.34 GHz, they can use the tinySA classic as source, if they have one. 5.34 GHz / 6 = 890 Mhz 5.34 GHz / 7 = 762.857140 Mhz. Using HIGH OUTPUT

Thanks for the idea, Jeff. I did some tests with an attenuator in line to reduce the input signal level and still observed the discrepancy. Ed, K0KC k0kc@... http://k0kc.us/ | |

I received a replacement synthesizer from Q5 Signal today and ran some tests which definitely showed that the two TinySA Ultra devices respond differently at the higher frequencies. I made sure that

OH Hell! I forgot to tell you to download thee dfu utility. Go to where Erik told you to go. larry

Erik, you may have seen my posts in this thread: /g/tinysa/topic/97851892 Trying to measure a? 2.2 kHz tone at 2.5 to 3 kHz deviation, sometimes the 3 markers would be all on one

Jim is correct. Having been in the two-way radio business (years ago) I know about pre-emphasis.? You'd think I would have considered that before making the comment about the deviation being the same

I thought this might be of interest to group members.? It is an easy to read tutorial on? three methods to measure Noise Figure.?? Two of the methods are applicable to the tinySA.

As do I. ?On the wiki page is a command: *dfu-util -a 0 -s 0x08000000:leave -D tinySA.bin . * Download the firmware and remove the part of the title showing the version number i.e. everything after

Wim Thanks for the feedback, I will improve the spec. -- For more info on the tinySA go to https://tinysa.org/wiki/

Eric, Where can I find the tinyPFA release? Mike N2MS

In the spec of the ultra rf -generator is says step size of 44 Hz, but i measured 57.2 Hz. Step size of 57 Hz, gives freq gaps on chosen output frequency between 0 and +28 Hz or 0 and -28 Hz. My cal

Looking good Thanks Erik

New FW release Version V1.4082 Basic only Changes: - Bug solved: Markers give large negative frequencies -- For more info on the tinySA go to https://tinysa.org/wiki/

Hi Erik, tinyPFA 215 works fine. There are some issues with tinySA and tinySA_v1.4-81-gaed244c above 133.2 MHz it reads - 4 GHz in Low mode also the High mode is off. Further more I could not make

Thank you, Erik, for the quick release of the corrected FW!? It works fine on Ultra. Mirek Dne 11.04.2023 v 11:01 Erik Kaashoek napsal(a):

See new tinyPFA release. Can one of you test if OK now? -- For more info on the tinySA go to https://tinysa.org/wiki/

Hi, What Joe says, SA and SA4 were not effected. NanoVNA H4 was, tinyPFA still is. Thanks André
