Spikes in Network Analyzer

Open drJaser opened this issue 11 months ago • 6 comments

After upgrading FW on ADML2000 to v0.32 , Network Analyzer always shows some sort of sporadic spikes in response. The circuit is low pass RC filter, so nothing complicated.. image

I took another ADML2000 with the same FW (already upgraded to v0.32) from my colegue in the office and the result was simillar.

After checking the same setup with brand new one ADML (original FW version 0.25), result was OK image

My question is how to proper downgrade our (already upgraded) ADMLs back to original 0.25 firmware? Where I can get files and guidelines to do that ?

Thanks, Borut

Hi,

You can find documentation on ADALM2000 firmware updating procedure here: https://wiki.analog.com/university/tools/m2k/common/firmware .

And you can download the firmware version you need from the releases page of this repository: https://github.com/analogdevicesinc/m2k-fw/releases .

I would recommend trying the v0.31 in order to see if this issue still happens since v0.25 is a pretty old firmware and multiple improvements were introduced in the last years.

Regarding the issue reported above, we will try to reproduce it and see what's causing it.

Thank you! -Alexandra
