In this episode Shahriar reviews the long-awaited Keysight MXR-Series 8-Channel 6-GHz 16-GS/s Real-Time Oscilloscope:
www.keysight.com/en/pcx-30623...
The Infiniium MXR-Series is the first oscilloscope to offer 6-GHz bandwidth and 16-GSa/s sample rate on every single one of its eight channels. It also offers excellent performance (ENOB up to 9.0, noise as low as 43 µVrms, dedicated ASICs) which exceeds that of the previous S-Series scopes. This review is organized as follows:
00:00 - Introductions
01:02 - Instrument overview, front-panel and rear interfaces
04:09 - Full acquisition board teardown and analysis including analog front-end
19:29 - First power-on and impressions
20:48 - Comparison and experiments with the Digital Sampling FFT, DDC and RTSA modes
34:04 - Time-base accuracy, frequency counter and DVM experiments
38:30 - Real-Time Eye, Jitter analysis and Equalization capabilities
50:00 - Concluding remarks

Are the channel colors at the BNC's more clearly differentiated than is coming up on the video? My first impression was to note that channels 1 & 2 look very similar in colour and contrast. The button LED's look good though so I am wondering if it's just a lighting or video thing? Personally I prefer yellows and greens to be apart from each other. I'm also a little bemused there's an LED beside the also lit up channel buttons... two LEDS's in the same piece of panel real-estate doing the same thing? I would also have dearly loved a bit of Dave Jones style "feel-o-vision" on the hoz and vert button functionality. That being said, Shariar makes a powerful statement in a comment below "Think about the fact that we live in a world where you can watch the detailed operation/teardown of top-tier instruments for free" and yes, this is fantastic! And well done and thanks to Keysight for providing the unit and taking the time to make comments here to us viewers too!

@Thesignalpath 3 жыл бұрын

The colors look fairly well distinguished in person. The two LEDs perform two different functions. One LED shows if a channel is enabled and capturing while the other LED shows if a channel is selected (and connected to the vertical knobs). It is a good visual representation. :)
