FNIRSI-1013D "100MHz" tablet oscilloscope

Engineer.r152, thank you so much, you’re a star! Have a great weekend. It’s nice when someone can help others. all working now

What is the "DC shift calibration" function?
When I activate it, some numbers appear in the channel sensitivity side menu, but I don't understand what they represent.

[Atlan]

I would read the instructions or watch the video.

Hello Etrius have a look at my video of how to via you tube regarding DC calibration .. https://youtu.be/81gYnOh9r8s

Hello Etrius have a look at my video of how to via you tube regarding DC calibration .. https://youtu.be/81gYnOh9r8s 

Thanks, I wasn't aware of this video.
My device actually needs an offset correction, and I didn't know how to do it.

[Etrius]

I'm very satisfied with the work done by all the developers who contributed to creating a truly excellent product, much better than the original, and I'd like to thank them all. Now that I've calibrated the various offsets, it's definitely reliable, useful, and functional. I'll always use it in all normal contexts.
Just curious: is the FFT function disabled in the latest release, or is it just me who can't enable it?

[Russell2024UK]

Etrius, yes, you're right—the FFT function is disabled in the latest release. We're confident it will return in time 

[Etrius]

Thanks for the feedback. I was just curious and not a request at all. I mainly use it in digital contexts, and having a large number of samples was a requirement; now it's completely satisfied.
I don't think I really need the FFT function, and I think many others, like me, don't have this real need. If it's available, it would certainly be a welcome feature. You've already done a lot of work, and I thank you all.

Currently, one person is working on the fpga, and I sometimes modify the DSO fw as needed and for testing. The person who implemented the FFT did not contact me, so it is a separate branch of development, there is also another generator menu there. (The original intention of the generator menu was to allow connecting generators like the 6900 via USB and controlling them via the oscilloscope display, so there are some parameters that are not relevant to the oscilloscope) in the first line where there is a switch, there should be a menu for selecting the generator and channels ch1 and ch2 on the generator

Does the Hold Off feature work using standard 1013D with firmware v1.00q2 ? thanks 

[Atlan]

All trigger settings are implemented in the fpga. This means that the standard fpga only allows what the FNIRSI company wrote there. But don't worry, the hold off is not programmed in the alternative fpga either.

[Russell2024UK]

thanks for letting me know

Hi Were you aware of the two setup functions for the 1013D — Voltage Calibration and DC Shift Calibration — shown in my attached videos below 

With the Voltage Calibration process, the stored values will be lost, so it's important to carry out the Voltage Calibration first, followed by the DC Offset/Shift Calibration.

Going forward, these settings can be stored within the 1013D oscilloscope. Using the Update section on the boot-up page, once you have saved the settings above, they can also be backed up to the microSD card inside the scope. This allows them to be restored later if new firmware is installed, meaning you may not need to repeat these two calibration procedures each time.

To save the calibration data:
1.   Boot into the DSO 1013D Updater (bootloader mode).
2.   Press Upload Calibration Data.
3.   The calibration information will then be stored on the microSD card.

You can view the stored data by connecting the oscilloscope to your computer via USB and selecting the icon within the DSO 1013D Updater.
When needed, you can restore the saved data using the Download icon (located to the left of the Calibration Data option).

Has anyone got a simple step-by-step guide on how to upgrade or create the 1013D with the newer FPGA firmware? I’ve seen a lot of posts recently and many of the bugs seem to have been resolved now as of May 2026.

For the last few years, I’ve been following the basic 1013D setup i am using as today firmware v1.00q2, which has been great and already provides many improvements over the original firmware. I’m now at the point where I’d like to move further with it.

Could someone explain the process for using the newer FPGA firmware version that has been created — from the hardware side (soldering/modifications ) through to programming the SMD chips and getting everything running? I finally have some spare time and would like to learn and give it a go.

Thanks in advance for any guidance RCF

Good evening! First, you need to take a picture of the main board from the FPGA side and post it on the forum to determine the type of controller, further actions depend on this.

[Etrius]

Currently, one person is working on the fpga, and I sometimes modify the DSO fw as needed and for testing. The person who implemented the FFT did not contact me, so it is a separate branch of development, ...

An implementation curiosity: is the graph for the FFT just a mathematical calculation performed by the CPU on the data acquired by the ADC or does it require FPGA functionality?

[Russell2024UK]

Hi engineer.r152  thank you ... find a picture of one of my 1013D Oscilloscope's motherboard as requested could you advise please ? Thank you again  RCF

[engineer.r152]

Unfortunately, I can't help you with anything, I have a different FPGA and the firmware algorithm is completely different. On this forum, the firmware of your FPGA was discussed from page 144.

[Atlan]

Theoretically it is possible to use the SPI pins to upload the configuration to the EF2 fpga. I don't really want to get into that. One free pin is missing but it is not necessary.

[Russell2024UK]

Engineer.r152 thank you any way ... i will have a look soon ...

All trigger settings are implemented in the fpga. This means that the standard fpga only allows what the FNIRSI company wrote there. But don't worry, the hold off is not programmed in the alternative fpga either.

if we finish test the dual channel trigger in the fpga fw 2017/3017...i can try to start implement/test the trigger hold function

Hi,
I have a question.
Is it not possible to move the signals individually in terms of timing?
I need to be able to move them individually, whether it's two reference signals or a live signal with a reference signal.

Thanks for everything.
Video attached.
