I love your videos and kudos for the caps lock detector. This is much better that the guy who invented the momentary caps lock button.

[@spacexfan5199]

Great video! Can’t wait for the livestream tomorrow!!

I really liked that breadboard video! It really showed something useful. Maybe a video that repeat that test high-speed vs low-speed design of pcbs

[@geor664]

Great video. I get that low BW is synonymous with slow throughput and high BW with high throughput. However maybe I missed something when you equate narrow bandwidth with high resolution and vice versa for wide bandwidth. I thought that in the spectral domain, a wider bandwidth equates with the equivalent of allowing for a primary wave plus many more harmonics than a narrower bandwidth. More harmonics means that you can more faithfully reconstruct a time domain signal, given that you have available more of the higher frequency components? Could you explain how a narrow band IF is analogous to a higher resolution outcome? I'm genuinely interested. Thanks

[@KeysightLabs]

Good question! Here's the response from Matt: While it’s true that measuring over a wide bandwidth gives you a better idea of harmonics and neighboring signals, all of that bandwidth needs to be converted to a digital format for the instrument to analyze. Let’s say you’re looking at the response of a band pass filter with a pass band at 5GHz. You sweep your frequency from 1 GHz to 10 GHz so you can see how the signal behaves outside of the pass band. That entire 1 GHz to 10 GHz bandwidth needs to be converted to a digital format for the instrument to analyze and display. The instrument breaks the bandwidth into pieces and converts it one piece at a time. The width of those pieces is the intermediate frequency (IF) bandwidth. This is where it gets tricky because we have two bandwidths - the bandwidth we’re measuring across (1 GHz to 10 GHz) and the bandwidth at which we’re converting the measurement to digital (the IF bandwidth). When you convert wide portions of your test signal to digital, you introduce more random noise into your trace. So, converting smaller pieces of your measurement to digital by using a narrow IF bandwidth gives you better resolution.

[@geor664]

@@KeysightLabs ahhh, got it. Thanks makes sense now It's similar to audio band sweep measurements, where you sweep with a narrow passband filter. More accuracy, less noise. Many thanks

Haven't had to deal with Capslock issues in a long time... I just use Autohotkey to remap my capslock to shift-tab, and if I NEED capslock, it is now shift capslock... Here is the code, +Capslock::Capslock Capslock::+Tab

[@KeysightLabs]

I was surprised to find out how many people remap their capslock key

[@thomaskluck4164]

The more interesting question might be WHETHER THERE ARE ACTUALLY PEOPLE USING CAPS LOCK DELIBERTATELY. Never heard of any, not even in legends.

[@ozanerturk7944]

I have a question about IFBW. Can I select an arbitrary value of IFBW for my frequency span and # of points combination. Is there a rule for high freq spans or general for selecting IFBW? Thanks!

[@randomnameifyful]

can i just borrow one of those oscilloscopes to properly learn how to use one? :) i like the learning feature when you hold the button down. Learning electronics can be frustrating sometimes, mostly due to the extreme overuse of abbreviations.

[@KeysightLabs]

Your best bet, btw, is to look for a local makerspace or university that can give you some stick time

BTW I used to own one of those cell phones on the back bench, fell off the back of my car. Saw it bounce off the road in rear-view mirror. Went back, brushed of the dirt, reinserted the battery and turned it back on. They were built like tanks. Oh also BTW, I used to be a tank commander. ;-)

Lost a little over 7% of my savings because of the market crash this last two weeks and I guess I'll have to settle to buy one of those Hantek usb osciloscope. I'd love a proper unit but really can't affoard one. I have to be happy for all the winners though and I understand Keysight can't give a unit to everyone who wants one otherwise they wouldn't be in business long.

Your misusing the term BandWidth. Band width is a term directly relating to the operating frequency or spectrum of frequency present at any given time. Your trying to apply the term to Resolution. It's not working and not the proper use of the term. Many words are being misused today adding to the watering down of our language.
