Re: Tracking Generator for tinySA

 

Very frustrating. The V2 boards have arrived in Melbourne but are "on hold" presumably for Covid19 reasons.

Hi Gyula,

The item number does not come up for me.

Re: Tracking Generator for tinySA

 

It wouldn't be too hard to have another version of my PCB Gerbers to cater for that pinout if required.

In hindsight, I also realized that the foot layout is different from the B3555.
The Polish seller put it up again as a 50pcs item, so far it has had 2 buyers and more than 10 leftovers. So you can try whoever still needs it.

Re: Tracking Generator for tinySA

 

Mouser also stock B3760, which has the same pin outs as the B3555, slightly wider passband and different matching parts.
I was wondering about using those for the analyser, and the B3767 with centre frequency 447MHz, also stocked by Mouser and also with the same pin out, for the tracking gen, though thinking about it as the B3767 response is narrower it may be better to use the B3767 for the SA and the B3760 for the tracking gen.

Then we could have a two channel analyser if that is of any use.

The problem with Mouser, in the UK at least, is the minimum order for free postage, which is otherwise prohibitive.??

Hi Gyula.

Many thanks for that pointer. I don't know why I didn't see that offering earlier, especially since it is relatively local to me.

Re: Tracking Generator for tinySA

 

Speaking of SAW filters, Dave has cleverly put a mode in the ESP32 controller version to plot the response of the SAW filters.

It's pretty amazing how it corresponds nicely with the Data Sheet. (Data sheet is for one filter only of course)


Re: Tracking Generator for tinySA

 
Edited

Its a pity the NDF550 has a different pin out. Fine if a new pcb was being developed but right now, doesn't suit the pcb with the original part. Seems like the Polish guy is the only one with readily available parts right now. And with Covid19, not easy to get. I also wonder how many more he may have available. Probably started with a reel of them.

I took a close look at my V2 pcb. It would be very difficult to fit these even with track cuts etc.

Hi Glenn

Yes, I was aware of the small mods to V1 but tidier is something to aim for, mostly. Not sure what your plans for Gerber release are but if available later I'll get an order off to China and distribute the pcbs among the NTARC members back home.

For the moment though, we share some of your lockdown pain, as we are actually in East Gippsland , on the Lakes and in Level 3. Can't readily go home for the moment, as we would have to go into self-funded hotel accommodation, and also put the dogs in kennels, for two weeks. Would get fairly expensive so we are sitting it out here on the boat. At least this time around, boating is permitted, subject to social-distancing etc.

Spent some of the time ordering the modules etc for the spec analyser. Surprisingly, some orders from China are arriving within pre-COVID times but others definitely aren't. Ran into trouble with the? SAW filters though. The Polish seller cancelled the order on the basis that he couldn't ship to Australia because of COVID? postage restrictions. Still have to solve that one.

For tracking gen, a 2nd RF board is stacked with the SA RF board and ESP32 controller, forming a sandwich of 3 boards. Plus TFT display.

Here is my lash up tracking generator using two SI4432 into a ADE-25 mixer, the test object is a qrp-labs 20m bandpass filter, the analyser is my homebrew ESP32 version.? Ugly!


Despite no filters on the tracking gen or shielding anywhere it seems to work quite well, almost identical trace to the nano-vna.? The tracking gen IF is offset 600kHz from the main SA IF.

The chart below is from the web client.

Re: Updated #tinySA tinuSA code #tinysa

 

Compiling the tinySA.ino without ui_sa.* and sa_core.* delivers the error message "ui_sa.c: No such file or directory" - see att. "error message"
After removing the line #include "ui_sa.c" from tinySA.ino the compilation and upload to arudino zero worked. - log "successful upload"
But when starting the window app. "tinySA.exe" I got the error message "no sweeper found"
Starting the tinySA.exe a 2nd time the serial port selector offers only "Mockup" and no serial port.

Could it be that the tinySA.ino maybe belongs to a different project eg. the tinySA with touch display? I ask because to enable the compilation I had to add a Lib XPT2046_Touchscreen

Thanks for your help!

Peter


Re: Updated #tinySA tinuSA code #tinysa

 

leave the Arduino IDE, delete ui_sa.* and sa_core.* and try again to compile

ui_sa.* and sa_core.* where intended for a backport that never happened

Hi Erik,

When using the files to program the Arduino I got a error message "'M_LOW' undeclared (first use in this function)" - see the attachment.

Please can you check if the files you uploaded in /Arduino? are the right one?

Thanks
