Very nice, I'm sure I'll be adding a couple of those onto my next Mouser order.
Edit: do they spec the Er?

I would have thought that the variability of anything you would use as conductors on the topside would be more significant than the likely difference in Er. I'd simply assume 4.2.

Hi,
I have discovered that BG7TBL's 35M-4.4G USB Signal Source (based on ADF4351) generates a quite nice square wave with fast edges around 200ps.
Measured with my TDS520B-500MHz (in fact ~650MHz --> Tr=~538ps)
Michel.

Don't really have a fast pulse generator, but I can show some relatively fast rise time on my RF gen.. as captured by the RTM 1054
I can reliably see the signal up to 1.2Ghz.. even up to 1.8Ghz is somewhat visible but the trigger starts failing pretty often at that frequency.

Thank you all for the postings. I just got the Siglent SDG2042X, at 1Mhz the square wave is acceptable, at 5Mhz starting to degrade very bad, etc. I thought I got a defective device. I need to dig more into how these things works. How the square wave is generated, etc. Reading your post helped me understand that I did not get a defective generator.

Might get better results with ARB mode=DDS and using square from built in ARB wfms.
