SCOPE Bandwidth setting is not working

[tmk2z]

Hi,

I am trying to use a SCOPE "20MHz" Bandwidth setting on ADP3250. However this function looks not working.  How do we set to be available for bandwith setting?

Below is OSC waveform, first 200MHz bandwidth fileter setting and second is 20MHz bandwidth. I expect this waveform on ADP3250.

1. 200MHz bandwidth

2. 20MHz bandwidth

But using waveform, Bandwidth setting is not working as below.

3. Waveform Bnadwidth "FULL" (Ver 3.19.11 64bit)

 

4. Waveform Bnadwidth "20MHz" (Ver 3.19.11 64bit)

 

Can you help to use "20MHz" bandwidth function?

Regards,

Hi @tmk2z

Above you compared 40ns/div with 500ns/div.

Here C2 is with full bw (55-80MHz) and C1 20MHz -3dB

 

Latest beta version adds digital filters, 128Mi sample capture, scope to awg routing.

Hi I have updated new WaveForm to 3.19.18 from 3.18.12. Then WaveForm firmware will be uodated automatically. Therefore AWG wave amplitude are changed. So I am evaluating results, all of them I can't use these data... Can you advice me, why level setting is changed? And how do we fix it?

Regards,

Hi @tmk2z

Could you provide more info like a screenshot ?

I don't see such problem:

Hi, 
I am using "SDK" on VC++. Now offset parameter and capture result are strage... I'd like to move back to previous version about waveform...
But when I updated this version, firmware also updated autmatically... 
How do I bakc to previous version like 3.17.XX? Can I change to old firmware?

Hi @tmk2z

I would recommend using the newer sw/fw version since it brings new features and fixes.
It would be great if you could provide more info about the problem you see, to fix it if needed.

To reprogram de device fw, hold down the Ctrl key and press Manual Refresh (or wait for the Auto), under device options select Update All.
After it is done, it may be needed to manually reset (or toggle the power switch) the device.

Hi 
I got a OSC capture data to use  a dwfcmd.exe. Using this exe, capture result was strange as attached. 

Can you give me advice?

C:\Program Files (x86)\Digilent\WaveFormsSDK\samples\dwfcmdCapture_Result.xlsxanalogoutrecord.txt

I am using latest version.

Hi @tmk2z

The newer beta software supports ADP3X50 capture for 1 channel up to 128Mi or for 2 up to 64Mi or 3-4 up to 32Mi samples, all up to 125MHz. 
You could use normal capture like this: analogoutcapture.txt

Next version will fix the glitch with record, where initially a set of dummy samples are returned.
Thank you for the observation.

Hi Thank you for your investigation.

I need to use this feature, as soon as possible. Please tell me release schedule of next version for this fix?
