Re: File /WA2FZW - M0WID ESP32 - ILI9341 Version of the TinySA/simpleSA_0_11.zip uploaded
#file-notice
Hello,
I did some tests again!!
I reversed software Analyzer? spectrum and tracking.
From a physical point of view, it is the same at the level of electronic components.?
Modified the CS of si4432 to select the correct chips? and reversed the libel of the PE4302 lines to match the PE4302 TG as a PE4302 analyzer.
Inevitably the entry is no longer in J14 but? in J13.
The tracking part then behaves like a spectrum analyzer, but the display is a bit different as if the 433MHZ filter seem (??)? not working properly.
It should be noted that you can change its value as you want, no effect.? ?See the pictures
So two cases:
Either the filter has a problem, or there would still be a software factor to be seen about. your opinion cdt |

Hi,
Does not hold this assertion on the message above "I think this one should be in Low in signal generator mode and not in High as in lowspeed analyzer. I think not possible to have lowspeed and signal generator on the same time
it's theorical. to be seen I was refraining from tests" cdt |

Hello Joerg,
You have, I think, a somewhat different design if there are 2 RF cards.
There must not be an RF? "switch" as on the latest M0Wid design.
I think this one should be in Low in signal generator mode and not in High as in lowspeed analyzer.
I think not possible to have lowspeed and signal generator on the same time it's theorical. to be seen I was refraining from tests

Hello Joerg,
Thank you very much for your tests
I am in uncertainty and thanks to you I will move forward.
we will be interested in version 0.15 and SimpleSa with M0wid PCB
First: You must ensure that you have the following information for the tracking generator in the My_SA tab:
Lines possibility to uncommed and / or add
? ? ? ? #define TG_IF_INSTALLED? ? --->see if not comment
#define TG_LO_INSTALLED? ?-->see if not comment
#define TG_ATT_INSTALLED --->see if not comment, possibility to add
Second: See also in My_Sa tab the frequency of TG_IF fonction of your filters on the PCB. You can have 433Mhz filters B3555 both on the 2 chains (see the sch¨¦matic) //#define TG_IF 447725000 // IF of M0WID build TG using 3767 SAW filters
#define TG_IF 433960000 // IF of M0WID build TG using 3760 SAW filters (swapped) ---> B3555
If you made some modification, you have to compile and upload the ESP. NOW: the findings: your tracking generator (like mine) does not seem to work (Subject to the changes I indicate)
Your signal generator seems to be working, not mine.
Your reference output must work (You did not specify it), mine works.
My bandscope and the RBW do not work on the internet view.
If I launch the bandscope on the internet view , it reboots the SimpleSA.!!
?
I made additional tests by changing the CS value of each SI4432 module and I was able to move the reference output to the GPIO output of each module successfully (Frequency value set. 1/2/4/10...etc Mhz)
This does not mean that the RF output of the module works, I can not test because no oscilloscope 1G bandwidth.
I still checked the welds and so on under the microscope. Ras.
Tested continuities, ras.
I have a small nanovna, I think I can test the filters with it.
However, it is possible to measure the output frequencies of the SI4432 modules.
I¡¯ll see about that.
?
For your part, you can check the reference output and especially see the parameters in My_SA for the tracking generator (See if it works after a possible modification)
Thanks for your help.
happy to be not alone!? cdt |

Hello Gerard,
I just checked, which SW versions I have on my SimpleSA's: - I have 1 with V2.8, that I modified to work with a 480*320 pixels ILI9488 display (I have only been successful with that version). This seems to have a HW issue after >3 years (SW Build time Feb 13, 2021, HW build is older0) - I have one with V0.12, which seems to work fine but it has only one RF board, i.e. no tracking generator - I have one with v0.15 with 2 RF boards, i.e. the HW for a tracking generator --> in my test yesterday, I have not been able to get the tracking to work... I also tested the web interface: the normal sweeping works, but the waterfall did not work. The signal generator mode is working: I was able to get an output signal between -60 and -20dBm out. The RF signal is coming out at the RF input/output. BTW: if you want to calibrate the "CONFIG/CALIBRATE/ACTUAL POWER", you have to run that twice. Upper left: Commercial TinySA Ultra Upper right: V0.15 with 2 RF boards Lower Left: V0.12 with 1 RF board Lower Right: V2.8 with ILI9488 3.5" display, which after 3 years has HW problems, as this is NOT on PCBs, but hand- and breadboard wired -- Joerg, DB2OO |

Hello,
I will give you a few elements of progress:
1) I repeated a check of the welds and components, possible short circuits, etc.
Nothing to report.
2) Then I did a test by changing the address of the SI4432 modules.
If you put 5, (Attention do not duplicate) automatically the GPIO2 output of the chosen module? turns into reference output.
Of course, you have to compile and upload, then check with the oscilloscope.
The 4 SI4432 modules work. Reference output OK, choice of frequency OK
3)Other test, inversion of addresses between analyzer and tracking.
The tracking part actually becomes like an analyzer. it seems to work, although I could not inject a signal (see inter RF)
?
So I come to the same conclusion, there must be a problem in the software (I have version 0.15) and this since version 0.11.? That¡¯s my point of view
?
Only Dave can confirm what I said, so I¡¯m waiting to hear from him.

hi,
In the end, I don¡¯t know if it¡¯s here, as if we were blocking the whole tracker part?
see in the SimpleSA tab: */
pinMode (SI_TG_LO_CS, OUTPUT);? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
digitalWrite(SI_TG_LO_CS, HIGH); // make sure the module doesn't get selected //why? gerard

pinMode (SI_TG_IF_CS, OUTPUT);? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??
? digitalWrite(SI_TG_IF_CS, HIGH);// make sure the module doesn't get selected //why? gerard

#if ( ( PE4302_TYPE == PE4302_SERIAL ) && ( defined(TG_ATT_INSTALLED) ) )
pinMode (TG_PE4302_LE, OUTPUT);
digitalWrite (TG_PE4302_LE, LOW); //? Prevent TG attenuator from being selected

Hello Joerg,
Thanks for your answer Version 0.15 is here? [email protected] | Homebrew spectral analyzer #1747 /g/HBTE/attachment/1747/0/simpleSA-v0.15.zip 1)? some confusion for the I/O connexion for the tracker, you have to verify yours my PCB? have these connexions (mecanic connexions controled on the pcb)? ?--> so in the My_SA tab? parameters /*
?* OOPS!? M0WID got the TG CS crossed on his PCB :(
?*/
#define SI_TG_IF_CS25? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??// pin to use for tracking gen IF SI4432
#define SI_TG_LO_CS 2 // pin to use for tracking gen LO SI4432
2)? Your attention: You have to modify the WIFI parameters for the connexion (yours) 3) Your attention:??You must enable tracking by decoupling and adding a line on the my_SA tab to have /*
?* Comment both lines below out if you do not have the tracking generator
?* If only one SI4432 comment out the TG_LO_INSTALLED line
?* Leave both uncommented if you have the two SI4432 TG option?
?*/
#define TG_IF_INSTALLED
#define TG_LO_INSTALLED
?
#define TG_ATT_INSTALLED? ?----> to Add also
4) Your attention:?Verify this value if your have TG filter 433 or 470 Mhz /*
?* If TG_IF is not defined then an offset is applied fom the main IF
?*/
// #define TG_IF 447725000 // IF of M0WID build TG using 3767 SAW filters
#define TG_IF 433920000 // IF of M0WID build TG using 3555 SAW filters (swapped)
?
?
/*
My results: The wifi connexion Work The reference generator work Low? and High sweep work? ?--> i have to to understand how work the atteneators?? The signal generator seem not working The Tracking seem not working may you try it on your SA? with version 0.15? Strange: if i select the band scope on the tactil screen it's seem working. If i select it on the wifi view, the SA reboot! Some other things to test... In conclusion:
I checked everything on my pcb
I try to decode? the software, nothing seen abnormal (But I¡¯m not a programmer)
But I have a doubt about a possible bug....
?
that¡¯s why I need to know if it works with M0wid¡¯s PCB design?

hi,
?
Can someone confirm that the signal generator and tracking work in version 0.15 with the given circuit model.
I checked everything on my PCB. It looks good.
Strange all this.
Is anyone still here?

hi,
i also read some pb's with mixers and filter?provenance function It also complicates the task of whether they are good or not. test their impedance?

Good morning,
?
I reply to this old post (2020) because on my homebrew Simple SA, I have the same symptoms that Joerg, ex-DB2OO? (see his screenshots)
Yet I have a version 0.15
Dave said these issues were fixed in version 0.12? so ????
So I go in circles because I¡¯m looking for a hardware failure or design flaw, when everything looks good.
May someone confirm that everything works on his homebrew SimpleSA? (Low sweep, hight sweep, signal reference, signal generator, tracking, etc) and indicate his version.
If possible put it as an attachment (Zip)? ?to try on mine? (Wifi parameters to modify, you can erase your)
I sent an email to Gyula which has a version 0.14, but no return for now. (Can be passed in spam?)
?
Thank you for your fast feedback? |

Re: Homebrew spectral analyzer
re,
I think that¡¯s in line 308 of the Siglo tab
I am not an arduino specialist, but this line will only display "set frequency"
It must be modified to display the real? frequency value of the Generator Signal.
put what?
Well, that¡¯s not gonna tell me why I got nothing out. LOL
cdt if ( (oldFreq != sigGenSetting.Frequency) || (oldIF != setting.IF_Freq) )
{
rcvr.SetFrequency ( setting.IF_Freq );
xmit.SetFrequency ( setting.IF_Freq + sigGenSetting.Frequency );
Serial.println("set frequency");
if (sigGenOutputOn)
{
delayMicroseconds(300);
SetRX(3); // both LO and RX in tx mode
}
changedSetting = true;
}
?
oldFreq = sigGenSetting.Frequency;
oldIF = setting.IF_Freq;
oldSigGenOutputOn = sigGenOutputOn;

Re: Homebrew spectral analyzer
Hello,
I was busy for several months on other things, including troubleshooting YokoGawa oscilloscopes and Rigol.
I took over this project.
I had a Si4432 module out of service and I replaced it. (U13)
I did a first test with the generators.
The reference generator works well in output J12.
I can adjust the frequency and the output to the oscilloscope ( so on 1mohm 12pf) is 50mv . (To check)
I actually have a doubt about the signal generator which should, in theory, come out in J14 (anyway, I have nothing on the other 3 connectors).
Honestly I do not remember if it worked before changing U13 (Like what, it should be noted)
?
Now init of the 4 modules SI4432is good, but the log of the signal generator seems strange to me.
If you change the signal value or calibration, it gives it in clear.
But nothing for the frequency.
I¡¯ll take a look at the app
your ideas. look here the log: sigGenLow - rxDrive set to 4, attenuation set to 9, cal is -1? ? ? ? --->Good for me
sigGenLow - rxDrive set to 4, attenuation set to 10, cal is 0? ? ? ?--->Good for me
set frequency? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ----> Strange no value???
sigGenLow - rxDrive set to 4, attenuation set to 10, cal is 0? ? ? ?--->Good for me
sigGenLow - rxDrive set to 4, attenuation set to 10, cal is 0? ? ? ?--->Good for me
