AD9951 Amplitude

Hi,

I removed 0Ω resistance after transformer(DIFF ⇒ SE), then each output of AD9951 shows 500mVpp before Trans and  1Vpp after Trans.

Hi,

I also find this somehow mysterious. Will have to setup a bench test next week for us to verify this one. We're still waiting for some components to arrive. 

Also can you verify the new output given on your latest comment? It seems like the one you sent is just the same as the first one. 

Regards,

Jules

Hi Jules,

Thank you for your reply.

I'm looking forward to see bench test.

⇒I attached pdf on my latest comment and it's page 2 have removed 0Ω and waveform.

Hello,

Thank you for your response. Apologies for overlooking the 2nd page.

Anyway, just want to ask the output after the filter? So we can also verify it on my end. 

All the best,

Jules

Hi Jules,

output after the filter shows about 290mVpp with 51Ω after trans.

See green waveform on page1.

Hi,

Apologies for not specifying. I was referring to the one after you removed the 0 ohm.

Hi Jules,

I updated three waveforms,

Could you check it?

 ・original Circuit(0Ω)

 ・Fixed Circuit 1(51Ω)

 ・Fixed Circuit 2(R1168=No Mount)

Hi there,

Apologies for responding late. Still waiting for the components to arrive. I will send you an update once we will start the bench test. 

All the best,

Jules

Hi Jules,

Thank you for your reply.

I understand your situation.

Hi Jules,

Do you have any update so far about your test bench?

Hi ttd,

It's been a while. Apologies for the late update. The parts will arrive this week. As soon as it arrives, I will give you another update once I commence the bench test.

All the best,

Jules

Hi ttd ,

I will now start the bench test. I will let you know once I get some results and will get back to you.

All the best,

Jules
