Hi @Nicolas Deup
You could use Logging/Custom

Thank you.

Hi @Nicolas Deup
You could use a global custom measurement like this to be very precise:
const thr = Scope.Trigger.Level.value; var ch1 = Scope.Channel1; var ch2 = Scope.Channel2; var data1 = ch1.visibledata; var data2 = ch2.visibledata; var cnt = data1.length; var i1 = 0; for(; i1 < cnt; i1++){ if(data1[i1]>thr) continue; i1 = i1-(data1[i1]-thr)/(data1[i1]-data1[i1-1]); break; } var i2 = 0; for(; i2 < cnt; i2++){ if(data2[i2]>thr) continue; i2 = i2-(data2[i2]-thr)/(data2[i2]-data2[i2-1]); break; } (i2-i1)/Scope.Time.Rate.real;

Hi @leonvs
Thank you for the observation.
It is fixed in 3.19.23
 

Thank you very much for the answer and screen shots!

Thank You,
Got it working now

That did the trick! Perfect 😁

Hi @JAlaj
For custom pattern up to 32Ki sample, first add signal or bus in Pattern Generator then Edit, select Custom and Import.
For Play/Record use File/Import in Logic Analyzer.

Hi @Philipp
FDwfDigitalOutRepetitionSet(hdwf, dio, 2*nRepeat) low-high repeat, so 2X period
FDwfDigitalOutDividerInitSet(hdwf, dio, cDelay) count in system frequency periods

Hi @JimR2 @artvvb
The sync mode implementation can capture up to one sample per system clock, default 100MHz.

Hi @cephy
Known:
-in Scope under time Options uncheck "Acquire Noise" otherwise it will give an error !

Hi @xchg.ca
Please uncheck the "acquire noise".
Sorry for this issue, but the application is in the middle of implementing few new things and this seems to be broken.

 

Hi @xchg.ca
It many be related to the newer driver installation method.
Did you get any error/warning during installation?
The FTDI driver should also be installed automatically from Windows Update or you can install it from:

Hi @xchg.ca
I've added support for this in the latest version:
Edit: return 0.044 + 1.333 * Step / ( Steps - 1 )

Thanks @attila that's just what I wanted.

Man, you always deliver the goods! Thanks so much!

Hi @anne
Combined XY plots are available in WF v3.18.16 and newer.
https://digilent.com/reference/software/waveforms/waveforms-3/start
https://forum.digilent.com/topic/8908-waveforms-beta-download/
Select X2 other than OFF, Y2 option will appear.

https://forum.digilent.com/topic/8908-waveforms-beta-download/
WaveForms 3.19.18 brings for Eclypse Z7 Zmods the following:
- deep capture for Scope (Zmod Scope and Digitizer) 256Mi and Logic Analyzer 128Mi samples, all up to 125MHz
- IIR filter channels performed in the device
- the Wavegen channels can be controlled from the Scope interface and digital outputs captured
- the Scope inputs (raw ADC, averaged or filtered) can be output to the Wavegen channels, as signal or as amplitude, frequency, phase modulation or summing
- DIO 14/15 can be used as trigger IOs
Limitations:
- when more than 4 capture channels are enabled the max sampling rate is 62.5MHz
- the IIR filter is optimized for high speed with lower resolution and due to this in certain conditions it can saturate, like with narrow band or high sample rate/frequency ratio
The QSPI firmware is updated automatically, for SD card boot mode and initial QSPI programming see the Help tab/ Eclypse Z7
 
AWG1 -> Scope1 -> Scope3 (Scope1 IIR)
AWG2 -> Scope2 -> Scope4 (Scope2 IIR)

 
AWG1 -> Scope1 -> Scope3 (Scope1 IIR) -> AWG2 -> Scope2
AWG1 -> Scope5 output
AWG2 -> Scope6 output

Thank you so much @attila, I appreciate the diagnosis help even though it didn’t end up working out! I will be in touch with customer service shortly!

Hi @bryan78
Protocol.Debug.value = 0/1

Hi,
I'm a long time (over 10 years) very happy Analog Discovery user. I just took delivery of a Digital Discovery. A fabulous instrument, but I seem to have only one of the cables for the I/O function (the smaller connectors). Is this a packing error, or is only one supplied? I hope it's the former, as it would be disappointing to need to buy another cable.
Thanks for reading.

Thanks, looks perfect :)
 

Something must be up with the power supply. I haven't been able to measure it yet because I left my multimeter in the office on accident, but the scope powered up with 19V from my benchtop power supply.
Thanks so much for the quick answers! I'm incredibly relieved it's something so minor.
Thanks,
Jason

Amazing, will try tomorrow! Thanks 🙂
