Re: ISSUE REPORT: New release: improved screen capture and better trigger status

Herb,

Did you test with v0.3 HW.
?I tested and it did not work.

Kurt,

Something broke during the latest updates before the release.

Re: Listen to received signals?

#357

Not possible in this HW version.

Listen to received signals?

After reading all the buzz I ordered one from Aliexpress. I see there were twenty orders from them in the last day or so1

Is there any way to LISTEN to the displayed signals?

Hi Erik

Correction to my mail. The markers work on all three PC’s. MY fault not to provide an input signal of adequate strength. The small spikes on the noise line is not adequate to trigger the marker whivh is quite goof ? Sorry for the noise

However I tried the TinySA-Saver and you recommended only to use the S21 Gain. It control the TinySA for a segmented sweep but nothing seen on the S21 Gain screen Any special tricks apart from setting the S21 scales

Hi Erik

Quite understandable.

Anyway it work now with various small flaws. There is no vertical lines for log sweep. On one computer the markers is not shown on another they are.

And do not change anything for storing when sweeping as stop sweep and do what you like to do such as subtract then sweep again, els crash .
It is a big step forward. I can switch between capture and sweep provided I remember to stop the sweep. !0000point no problem ?

Kind regards

Kurt

I haven't spent enough time in tinySA.exe lately with the various changes in the tinySA itself.

Re: tinySA-H4

#354

Yes it possible, but not need. This firmware need only as first step for move tinySA on new hardware (use STM32F303 and more bigger display module). Now possible produce tinySA based on H4 hardware (before use H hardware, but it have some limits, like no FPU, less flash size)

PS yes exist H4+ one SI4432 module as proto-board, but it used as signal generator only.

Re: Tracking Generator

#353

As explained in other post, you need either a second tinySA to act as tracking generator or you have to make one yourself with a mixer and a 433.9MHz generator using the LO output?

Re: tinySA-H4

#352

Interesting.?

Are you saying that it may be possible to piggyback a SI4432 module to the H4 so we can play more with the FW?

You can flash it to H4 and see how it work (yes no any tinySA hardware on H4, and you not see spectre, but all menus work, sweep times and e.t.c)

H4 allow SD card, so in next tinySA possible save something to it

PS STM32F303 have hardware FPU, and in it SI4432 run on hardware SPI mode, so it allow moew fast work, minimum Zero Span time = 700us, also values convert (if use Volt for example) less slowdown.

Tracking Generator

I notice that there appears to be no tracking generator.? Is this correct?

Thanks,

Hi Erik

The change of dB/Level to 32 got it to work

Hi Erik

Is seem to be able to run the sweep as stop the TinySA sweep when pressing single. If pressing Run the Tiny SA screen continuous stopped which I suppose it as it should be, but I see no trace. If setting the sweep on the TinySA it does not send frequency information to the TinySA. The Com port crashes quite often

Kind regards

Kurt

I REALLY HATE the windows serial port implementation in VC
If you do not see the serial port, unplug the device from USB and wait a second and connect again.

Re: External modulation function

#344

Hello Erik,

Thank you very much for the response and the information. Would it be possible for an external modulation feature to be added in a future firmware revision?

- Mike

Re: External modulation function

#343

The low output signal is created by mixing a fixed 433.9MHz signal with an LO at 433.9MHz + the required output frequency.?
The external modulation option disables the build-in LO and connects the mixer LO input to the high port. So a better name should have been "external LO"
In this configuration you can use two tinySA's to create a tracking generator option with a possible offset (within +/- 500kHz) by connecting the high input of the tinySA in external modulation mode to the LO output of another tinySA.
This is exactly how the tracking generator of the early HP spectrum analyzers worked.
See this post:?/g/tinysa/message/10
Disadvantage of the direct coupling as shown in above post is the reduced dynamic range (max 70dB) due to reverse leakage through the mixers of the two tinySA. This can be solved by putting an isolation amplifier in between.

External modulation function

#342

Hello,

I was reading through the documentation and was curious about the external modulation function. Does this allow one to input through the high input either modulated audio or a modulated tone that is of a different frequency from the built in 800hz tone?

Thank you,

- Mike
