Hi @A_Beta
AD2 and ADP3 can capture up to 100/125MHz. The Scope can be used in mixed mode by adding Digital channels.
The AD2 can record/stream up to around 1MHz. Depending on computer and available USB bandwidth.
The ADP3 in standard can record up to 128MiS@500MBps, for 2 Scope and digital channels about ~40MHz rate, for 4+digital ~20MHz.
The digital bandwidth usage with data compression depends on signal activity rate.
As a last minute change, in the latest version the digital rate/samples adjustment is enabled for recording but it is still automatically set to analog values if these are changes. So adjust digital rate/samples under Options every time before starting a record and make sure it is not longer than the analog time. I'll try to optimize this in the next versions.

Hi @WojtekO
For custom board you could use 3.3V relays so you don't have to boost to 5V.

Hi @WojtekO
To test this I've hooked the IA module to ADP3 with some wires.
I let the relays driven by 3.3V which is much lower than the 3.75V relay spec but it is switching.



 

Hi @attila
Great job!
i'm going to draw a adapter board !

Thank you so much for this beta version. Best regards. 

Hi @WojtekO
It will be in the next version.
The AD IA Adapter could be hooked to ADP3X50 using the DIOs (4-7, 12-15), 2 Scope, 1 Wavegen channel and 5V from the USB connectors at the back.

To fine tune the setup use a pF capacitor, Ref 1M and adjust the Options/ ProbeCap to have a flat response.

Hi @Kota Uchida
See the application Help and examples.

Hi @johndah
Is it safe to switch off the ADS while it is connected by USB to a powered PC?
Yes
Does the headphone jack have an audio amplifier? Can the headphone jack drive a 4-8 ohm speaker directly?
Yes, see: https://digilent.com/reference/test-and-measurement/analog-discovery-2/hardware-design-guide#audio
Is it safe to have an external audio amplifier powered on and connected to a powered off ADS?
Yes, but the make sure the equipment has the same grounding as the ADS and computer since these will be connected via audio and USB cables.
Is the USB A port a functional hub node? Is it safe to plug a USB FT232RL dongle on the hub while the ADS is powered on or off? Note that I don't intend to use the ADS as host.
Yes, the USB is plug and play.
I would like to replace the breadboard canvas breadboard with another one. Is it safe to remove the screws from the canvas?
Yes, but while powered off to prevent accidental shorts on the pogo pins.

Hi @attila,
Thank you for the response! I've tried both blowing and brushing the connection port, no success. I'll look into warranty and replacement. Thank you!

Thanks alot @attila. I'll look into this

@attila
Okey no problem, thank you for the answer !

Uninstalling the device worked! The device is now recogniced by the SW. Thanks a lot.

Hi @Hatman
The WaveForms application Scope measurements are not available in the SDK.
The Spectrum/FFT peak with weighted average should give a more accurate frequency measurement.
For this you could use the newly added FDwfSpectrum# functions.
 

Hi @MarcusD
High frequency signals get attenuated due to bandwidth limitations, more on Wavegen output than on the Scope input for AD2, see:

@attila
Thank you !

I downloaded it from the link provided, and this solved my problem.
Thanks

Hi @attila,
Thank you for your help. I was running the Analog Discovery 2 with a 5 volt adapter. As you stated, it needs to be powered with USB too. After I connected the device on RP4 with a powered USB hub, it was finally connected.

thank you very much! Now I understood what the StatusTime means! So if I measure the last StatusTime, it basically indicates at which time the measurement ended. Thank you.

Thank you for your information. I'll try to use latest version. Thanks!

Great!!! This worked beautifully!!
Thanks for the help :)

Thank you very much, attila!
 
I searched on the web for hours but I didn't look in the Help-Register on the Software.
 

Thank you

Hi Attila,
Thanks! no problem I appreciate your response!
Good news, arm64 3.18.19 seems to be working! I am reading out the samples with the correct values
Will you be having an example py file at some time? Having an example of doing it the right way would be very useful. (you can use mine if its of any use)
I took a look at your latest AnalogInOut_RecordPlay.py, I think the acqmodeRecord streaming mode could be more useful to me, (I've been using acqmodeScanShift so far)
thanks again

I found that installing the latest driver from FTDI (see this post) resolved my issue. I did have to uninstall all other drivers using their uninstaller tool.
I can confirm that I was able to use the Xilinx tools (SDK 2019.1 and Vitis 2022) to connect to our hardware using the JTAG-HS3 cable. This was running Windows 11 ARM in Parallels Desktop 17 on Mac Book Pro with M1 Max CPU. I can also confirm that this is running everything faster and smoother than ever before.
