how about 3.5 ps edge @ 113 GHz realtime bandwidth? >:D :popcorn:

Ahem. Can we see this with a usable horizontal scale ?
TheSteve:
I can't beat Daniel but am still pleased.

Ok, so it's not the fastest, but it's pretty fast. It's also driving 5V into a 50 ohm load.
Texas Instruments LMG1020 gate driver in BGA package driving 50 ohms, measured with a Tek DPO7354C. Room for improvement on connection to SMA, but not bad. The chip has separate pull-up and pull-down outputs, and the resistors connecting the chip outputs to the transmission line are 1 ohm resistors in 0402 packages.
Cheers,
John

Here is a screenshot of a signal from an ADF4351. I've gotten that part in order to better calibrate the MCP CRT of a 2467B in high frequencies. When programming with the arduino and testing, I was amazed to see that the part has quite fast rise times. Or do I understand something wrong, does the device measure wrong?
Alfons:
I have just converted the TDS744a in a TDS784a, which was done without problems. The bandwidth has doubled. Here is a picture of the same signal as yesterday. You can see how a narrow bandwidth smoothes the signal.
