In this episode Shahriar takes a look at another world's first instrument: Keysight M8199B 256 GSa/s Arbitrary Waveform Generator. With over 80GHz of analog bandwidth, this high performance ARB is intended for design development at 160GBaud and above:

This video is organized as follows:

00:00 - Introductions
00:54 - ARB comparison, performance metrics, key parameters
03:59 - DAC design, chip layout, system level considerations, overall instrument architecture
14:42 - M8199B interfaces, detailed teardown, sub-block overview, output module analysis
30:14 - Demonstration setup, M8199B, DCA-X, 120GHz remote sampling use-case
33:29 - Software interfaces, I/Q tools, signal generation & calibration
36:29 - DCA-X eye-diagram captures, 64GBaud to 200GBaud, NRZ, PAM4, PAM8
44:09 - Keysight captured eye diagram & ultimate system performance
45:50 - Concluding remarks

Thanks for showing this remarkable AWG, quite impressive indeed :-+

Way back we were interested in the DAC which ended up within the M8190A, which was called Griffin. Our interest was for "special signal" generation for "special applications". This DAC was in SiGe technology and was quite advanced when we were first introduced to it back in ~2009 at the IMS. It could produce NPR results better than 75dBc which we were shown during a personal meeting at the IMS!! Fun story about how this came about over a brew, will discuss if interested ;D

Here's a LR Crop Image from way back of Griffin.

Very cool!

Construct:
Incredible video, as usual.

I appreciate these high information density, low noise videos more and more as the years go on.

Thank you! And thank you for recognizing the effort which goes into producing high information density. :)
