OK Thank you
 

Hi @Anthocyanina
The next software version will add such option:

Hi @Anthocyanina 
The properties can be coupled with a Script like this.
If a disconnected is not called an application restart is required to get rid of the connection.

function doFreq(){Wavegen.Channel2.Simple.Frequency.value = Wavegen.Channel1.Simple.Frequency.value;} function doAmp(){Wavegen.Channel2.Simple.Amplitude.value = Wavegen.Channel1.Simple.Amplitude.value;} Wavegen.Channel1.Simple.Frequency.Sig.connect(doFreq) Wavegen.Channel1.Simple.Amplitude.Sig.connect(doAmp) while(wait()); Wavegen.Channel1.Simple.Frequency.Sig.disconnect(doFreq) Wavegen.Channel1.Simple.Amplitude.Sig.disconnect(doAmp)  

Hi @Abhijan
In-device Oscilloscope input to AWG output routing (+amplification, filtering) is only supported by newer devices AD3, ADP3X50...
With AD3 this adds a delay of about 20 cycles (200ns at 100MHz) or more with filtering.
 

Thank you very much. Exactly the information I needed.
The "Add" wording confused me...

I found a good site that generates PWM waveforms.
https://www.instructables.com/Analog-Discovery-PWM-and-Digital-IO-Control-though/
Considering my level, I need a simple "getting start", but ^^ I think this site will help a lot.

Hi @DKluger
The freq comp calibrates the ADC (oscilloscope) gain for some system frequency steps in the adjustable range 50-125MHz
The ADC and DAC are clocked by a low jitter clock manager which has ECS-250-18-36-AGM-TR as reference. This cannot be calibrated, the stability is given by the oscillator.

That's great. Thank you very much for the quick and informative response.

Hi @DKulkar
Yes, user calibration is supported for every device, including ADP3X50.

Hi @ysrevol
With the C API, see WF SDK/ samples/ py/ DigitalOut_Pulse.py

 

Hi @Mavitaka
The interpreter is available in the WaveForms application.
For custom app/script interpreter a loop can be used, looking for rising edge of the respective clock bit of the sample and storing masked value of the next sample, for 400MHz rate to have 2.5ns delay.

Hi,
thanks for your answer.
Adding an external pull-up resistor solved the issue.

Hi @timnrp
Try to use an external pull-up.
The inter pull-up on PB2 may be activated only after programming. During and before this the very low (~1M) pull-down from AD2 DIOs may hold the signal low.

Sorry for the slow response, it turned out to be a faulty connection. Somehow the pigtails were fully seated on the BNC adapter, but there was no continuity between the digital pigtail wire and the bnc adapter. Reseating it made it work 🤷‍♂️
Thanks for the suggestions, it did push us to recheck!

Hi @Mavitaka
The GPS satellites use atomic clocks which are extremely precise and these also take in account the time dilation.
I don't know how accurately does the receiver forward the signal but probably it is still more precise than any device using crystal oscillator.

Hi @Mavitaka
See the Counter in the Logic Analyzer.
Here 1Hz is generated by one device and captured by another. The difference is the crystal oscillators tolerance.

Thanks.
That helped dramatically.
I am in the range of 1mV now but with warming up it gets a bit worse again. Will calibrate one more time after warm up.
Cheers,
Andreas 

Hi @attila,
I set up the scrip on my work bench and it seems to be working ok now. Maybe there was an intermitent connection. I had my input measurement DC Coupled last time as well

Hi @Kuz
 

Hi @Mavitaka
Only the FPGA or Zynq development boards:

Hi @Mavitaka
The sampling of data lines should be performed on the same clock that the ADC receives, with the required phase to satisfy setup and hold.
If you are using Digital Discovery Sync capture mode you could try using falling edge instead of the rising edge, to have 180* shift.
With normal capture mode sample at least at 400MHz and interpret the data according the clock, like:

Fantastic.   I'll read and figure out what I needed to do,  looks like it was the RepeatTriggerSet I was missing.   Thanks from a newbie. 

I have swap to different USB hub, it works fine. Now I can adjust voltage for supplies.

Hi @Mavitaka
The highest output frequency with Digital Discovery is 50 MHz, half of the default 100 MHz system clock which is adjustable.

Hi @Mavitaka
Reference clock is not supported by Digital Discovery only Sync capture mode:
