where is this article? dave k7da

Thank you for your explanation. I saw the detailed instructions in this article (Tiny SA Operator's Manual (V2.8). pdf)

Thank you for your answer. Later, I found a use in this article: Tiny SA Operator's Manual (V2.8). pdf and,thanks again for your design. I plan to DIY myself recently

The reference generator output is a square wave output from the Si5351 that is intended to be used for calibration of the signal levels.? The frequency can be set at various divisions of the 30MHz

The various frequencies needed for the operation of the tinysa are generated in a frequency synthesizer chip such as the ADF4351. The synthesizer chip needs to have a reference clock to lock to.? In

What does Reference Generator Out do？

Hello Dave and others I ordered some components. I’m waiting for them before I start manufacturing the PCB. If you have any changes to make to your original schematic , please feel free to let me

RE, Sorry I have found the good version It's right now!! cdt

Hello Dave, Here that i have in line 303 of My_SA.h..... Nothing Line 303 is under? ?#define BACKLIGHT_LEVEL....... May you give the good version Thank you cdt

Hello Thank you for thr? information of connexion, it's done on the PCB The PCB is finished, a little enlarged, the grounds? under the filters are removed. Copper? planned to shield the 4432. Other

Hi Gerard, apologies for the delay.? I could not remember so had to open up my simpleSA to find out. I have a wire link between IO17 (J9 pin 1) and J2.? IO17 is labelled as TX2 on the ESP32

Hello, Nobody here since a week. If someone could give me an explanation for the connection of the J2 as requested above. Thank you

Good morning, Thank you for your answer, I’ll look into it. Nevertheless, I still have a question about 1 connection: If I follow one of the connections of the IRML2502 I go at the J2 connector. On

Hello Dave, For your information, I just put the 100NF in 1206 Only selfs and small capacitors are in 0805 The v-groove, I don’t know what it is, is it the middle of the card? For now I don’t know

I am not clear what voltage you will feed into the 7805, but the ESP32 when running the WiFi can demand quite a lot of current.? It would be worth checking you can lose enough heat.? I had some

Dave, Thank you for your response I’ve already spent time with Kicad to change some things for my personal taste. I already added the capacitor you’re talking about. On my side I put a classic

Hi Gerard. Apologies for not responding earlier but I have been extremely busy trying to achieve a deadline at work.? Just about made it. Yes you do need to modify the SI4432 boards as shown by

Good morning, Dave and all, I need some information: May you specify if you need to modify all the? SI4432 as shown in the picture? Seen on Site: http://www.carnut.info/tinySA/tinySA.html My SI4432

You have to read: Remove connectors J14 and J1 --> Direct connections Cdt Tell me if it crazy to do that.....LOL? ? ?FUN

Hello I’m modifying the PCB schema The idea is that I want to make more of a lab-style device than a portable analyzer. I have a Nanovna, and I only work with a PC, because an inch screen seems too
