This is our second-to-last lesson on the fundamentals of using oscilloscopes. 00:00:15.766 --> 00:00:18.644 align:center line:-1 position:50% size:48% Hopefully, you've learned something in these video lessons 00:00:18.644 --> 00:00:22.064 align:center line:-1 position:50% size:41% and have gotten a chance to actually use an oscilloscope 00:00:22.064 --> 00:00:25.943 align:center line:-1 position:50% size:47% to put some of the things I've tried to teach you into practice. 00:00:25.943 --> 00:00:30.489 align:center line:-1 position:50% size:57% Nothing beats actual hands-on experience when you're trying to learn something new. 00:00:30.489 --> 00:00:37.246 align:center line:-1 position:50% size:69% Hi, my name is Johnnie Hancock, Product Manager for Keysight's InfiniiVision oscilloscopes. 00:00:37.246 --> 00:00:42.459 align:center line:-1 position:50% size:46% In this lesson, we're going to learn how to document our test results. 00:00:42.459 --> 00:00:48.465 align:center line:-1 position:50% size:63% When your professor or lab coordinator assigns an experiment for you to build and test, 00:00:48.465 --> 00:00:52.094 align:center line:-1 position:50% size:56% they will probably want to see test results. 00:00:52.094 --> 00:00:56.473 align:center line:-1 position:50% size:49% There are a couple of different ways to save your setups and test results. 00:00:56.473 --> 00:00:59.601 align:center line:-1 position:50% size:55% You can do it directly on the oscilloscope, 00:00:59.601 --> 00:01:05.941 align:center line:-1 position:50% size:54% using either the scope's internal memory or an external USB memory device. 00:01:05.941 --> 00:01:12.030 align:center line:-1 position:50% size:67% Or you can do it online via an ethernet connection to your laptop. 00:01:12.030 --> 00:01:14.741 align:center line:-1 position:50% size:23% Let's get started. 00:01:14.741 --> 00:01:19.579 align:center line:-1 position:50% size:52% These are the input and output signals of the resistive divider circuit 00:01:19.579 --> 00:01:22.833 align:center line:-1 position:50% size:59% we've been using throughout these lessons. 00:01:22.833 --> 00:01:28.547 align:center line:-1 position:50% size:65% I hope your experiments are a lot more technical than these two resistors. 00:01:28.547 --> 00:01:33.969 align:center line:-1 position:50% size:52% I wanted you to focus on using a scope and not a complex circuit. 00:01:33.969 --> 00:01:39.057 align:center line:-1 position:50% size:52% Assume you get to a certain point in one of your experiments in your labs 00:01:39.057 --> 00:01:42.853 align:center line:-1 position:50% size:41% and you have to leave the lab, you haven't finished, 00:01:42.853 --> 00:01:47.190 align:center line:-1 position:50% size:56% and you want to pick up where you left off. 00:01:47.190 --> 00:01:49.443 align:center line:-1 position:50% size:53% It's not likely if you come back to the lab 00:01:49.443 --> 00:01:52.529 align:center line:-1 position:50% size:43% the scope is gonna be in the same condition you left it. 00:01:52.529 --> 00:01:56.616 align:center line:-1 position:50% size:58% One of your fellow students is probably going to have changed the setup. 00:01:56.616 --> 00:01:59.036 align:center line:-1 position:50% size:38% You need to save the setup. 00:01:59.036 --> 00:02:03.040 align:center line:-1 position:50% size:66% There are a couple different ways we can do that. 00:02:03.040 --> 00:02:07.085 align:center line:-1 position:50% size:47% There's a button on the front panel, says Save/Recall. 00:02:07.085 --> 00:02:08.128 align:center line:-1 position:50% size:18% I'll press that. 00:02:08.128 --> 00:02:11.757 align:center line:-1 position:50% size:41% Then you can have the choice of saving or recalling. 00:02:11.757 --> 00:02:14.468 align:center line:-1 position:50% size:23% Let's press save. 00:02:14.468 --> 00:02:17.095 align:center line:-1 position:50% size:45% Then, what do you want to save? 00:02:17.095 --> 00:02:18.722 align:center line:-1 position:50% size:45% Do you want to save waveforms? 00:02:18.722 --> 00:02:20.098 align:center line:-1 position:50% size:40% Do you want to save images? 00:02:20.098 --> 00:02:23.310 align:center line:-1 position:50% size:39% Do you want to save setups? 00:02:23.310 --> 00:02:25.354 align:center line:-1 position:50% size:34% Let's assume it's a setup. 00:02:25.354 --> 00:02:27.898 align:center line:-1 position:50% size:29% You can select setup. 00:02:27.898 --> 00:02:31.109 align:center line:-1 position:50% size:58% Then select down here, it says press to go. 00:02:31.109 --> 00:02:37.741 align:center line:-1 position:50% size:51% This is where you could save it to one of 10 internal storage locations, 00:02:37.741 --> 00:02:39.242 align:center line:-1 position:50% size:43% but those aren't very safe either. 00:02:39.242 --> 00:02:42.954 align:center line:-1 position:50% size:49% Your fellow students could write over that storage location. 00:02:42.954 --> 00:02:49.878 align:center line:-1 position:50% size:55% The best place to save it is to an external USB thumb drive that's yours personally. 00:02:49.878 --> 00:02:57.636 align:center line:-1 position:50% size:49% Put it in the USB port on the front, and then navigate to that USB drive. 00:02:57.636 --> 00:03:02.682 align:center line:-1 position:50% size:49% Then, you can give your file a name. 00:03:02.682 --> 00:03:09.272 align:center line:-1 position:50% size:62% This is Lesson 17, and that just happens to be what popped up here, Lesson 17, 00:03:09.272 --> 00:03:12.192 align:center line:-1 position:50% size:54% and you can have an increment up here. 00:03:12.192 --> 00:03:19.324 align:center line:-1 position:50% size:40% I could say press to save, and now it's saving this setup. 00:03:19.324 --> 00:03:22.828 align:center line:-1 position:50% size:46% If there's a second setup, I go in here and press save again, 00:03:22.828 --> 00:03:24.955 align:center line:-1 position:50% size:36% it's going to increment to 18. 00:03:24.955 --> 00:03:30.627 align:center line:-1 position:50% size:52% You can customize whatever file name you want to save it as. 00:03:30.627 --> 00:03:32.087 align:center line:-1 position:50% size:48% What if you want to save an image? 00:03:32.087 --> 00:03:38.760 align:center line:-1 position:50% size:64% Your professors are probably going to require you to include your measurement results. 00:03:38.760 --> 00:03:45.016 align:center line:-1 position:50% size:50% The best way to document it is to actually capture a screen image. 00:03:45.016 --> 00:03:46.601 align:center line:-1 position:50% size:18% Let's do that. 00:03:46.601 --> 00:03:53.066 align:center line:-1 position:50% size:52% I'll press Save/Recall, Save, Save Image. 00:03:53.066 --> 00:03:55.902 align:center line:-1 position:50% size:41% There are three different types of images you could save, 00:03:55.902 --> 00:04:05.287 align:center line:-1 position:50% size:67% an 8-bit bitmap BMP, 24-bit BMP, or a 24-bit PNG. 00:04:05.287 --> 00:04:08.707 align:center line:-1 position:50% size:49% The PNG files are the most efficient. 00:04:08.707 --> 00:04:10.834 align:center line:-1 position:50% size:30% That's what I suggest. 00:04:10.834 --> 00:04:13.044 align:center line:-1 position:50% size:47% You can give it a custom file name. 00:04:13.044 --> 00:04:15.380 align:center line:-1 position:50% size:29% This says Lesson 18. 00:04:17.507 --> 00:04:18.800 align:center line:-1 position:50% size:20% Press to save. 00:04:18.800 --> 00:04:20.552 align:center line:-1 position:50% size:36% Now, it's saving that image. 00:04:20.552 --> 00:04:26.641 align:center line:-1 position:50% size:62% You could pull that image, paste it into a Word Document or whatever other kind of document 00:04:26.641 --> 00:04:31.438 align:center line:-1 position:50% size:49% when you have to turn your report in to your professor. 00:04:31.438 --> 00:04:34.065 align:center line:-1 position:50% size:41% You can also save waveforms. 00:04:34.065 --> 00:04:35.984 align:center line:-1 position:50% size:8% Save. 00:04:35.984 --> 00:04:38.695 align:center line:-1 position:50% size:58% Down here there are several different kinds of waveforms. 00:04:38.695 --> 00:04:47.579 align:center line:-1 position:50% size:68% The most common is a comma-separated variable, .CSV type waveform. 00:04:47.579 --> 00:04:50.957 align:center line:-1 position:50% size:50% When you save a waveform like that, it's going to be an array, 00:04:50.957 --> 00:04:55.295 align:center line:-1 position:50% size:39% an XY array, times and volts. 00:04:55.295 --> 00:05:01.426 align:center line:-1 position:50% size:64% You could import this into an Excel spreadsheet if you don't have too many points, 00:05:01.426 --> 00:05:07.140 align:center line:-1 position:50% size:59% or you might want to import it into something like MATLAB to do additional analysis. 00:05:07.140 --> 00:05:12.854 align:center line:-1 position:50% size:57% Maybe there's some math function that's not in the scope but it is in MATLAB. 00:05:12.854 --> 00:05:15.690 align:center line:-1 position:50% size:44% You could import it into MATLAB. 00:05:15.690 --> 00:05:24.366 align:center line:-1 position:50% size:60% We'll select a CSV file name and press save. 00:05:24.366 --> 00:05:33.375 align:center line:-1 position:50% size:59% I should have three files on that thumb drive for the setup, the image, and the waveform. 00:05:33.375 --> 00:05:36.586 align:center line:-1 position:50% size:41% There's another way to save and recall information. 00:05:36.586 --> 00:05:38.713 align:center line:-1 position:50% size:32% It can be done remotely. 00:05:38.713 --> 00:05:46.179 align:center line:-1 position:50% size:57% This oscilloscope right now is connected via an ethernet cable to the LAN network, 00:05:46.179 --> 00:05:50.100 align:center line:-1 position:50% size:48% and I can interface it with my laptop. 00:05:50.100 --> 00:05:56.898 align:center line:-1 position:50% size:59% Let's say I want to save this particular image and pull it straight in to my laptop. 00:05:56.898 --> 00:06:03.446 align:center line:-1 position:50% size:61% First of all, I could go into the utility menu under I/O and find out what is the IP address, 00:06:03.446 --> 00:06:09.244 align:center line:-1 position:50% size:32% and it's 169.254.86.253. 00:06:09.244 --> 00:06:14.916 align:center line:-1 position:50% size:55% I've already entered that into the URL bar on my web browser. 00:06:14.916 --> 00:06:21.548 align:center line:-1 position:50% size:50% I can just press enter, and it brings up this oscilloscope's home page. 00:06:21.548 --> 00:06:27.596 align:center line:-1 position:50% size:37% If I want to pull in an image, I could say Get Image. 00:06:31.224 --> 00:06:33.602 align:center line:-1 position:50% size:41% Here is that image pulled over. 00:06:33.602 --> 00:06:39.441 align:center line:-1 position:50% size:62% If I want to save that image, I could just right click and say save image as, 00:06:39.441 --> 00:06:45.113 align:center line:-1 position:50% size:60% or I could say just copy and then immediately paste it into a document. 00:06:47.157 --> 00:06:50.201 align:center line:-1 position:50% size:57% We also have a Save/Recall button up here. 00:06:50.201 --> 00:06:55.540 align:center line:-1 position:50% size:45% If I want to save a waveform data or save a setup or recall it, 00:06:55.540 --> 00:07:01.129 align:center line:-1 position:50% size:45% and then you could put those files directly on your hard drive. 00:07:01.129 --> 00:07:05.300 align:center line:-1 position:50% size:59% There's one other thing you can do remotely that you might be interested in, 00:07:05.300 --> 00:07:08.637 align:center line:-1 position:50% size:52% is over here, it says Control Instrument. 00:07:08.637 --> 00:07:14.142 align:center line:-1 position:50% size:38% If I click that and then select Use Remote Front Panel, 00:07:14.142 --> 00:07:18.229 align:center line:-1 position:50% size:64% now it brings an image of the whole scope over, 00:07:18.229 --> 00:07:20.398 align:center line:-1 position:50% size:54% and I can actually control the instrument. 00:07:20.398 --> 00:07:25.236 align:center line:-1 position:50% size:52% Just imagine you're in your dorm room, you left your oscilloscope up in the lab, 00:07:25.236 --> 00:07:30.283 align:center line:-1 position:50% size:66% and hopefully you've put a fence around it so that nobody could disturb it and move the probes, 00:07:30.283 --> 00:07:32.619 align:center line:-1 position:50% size:53% and you want to finish your experiment. 00:07:32.619 --> 00:07:38.458 align:center line:-1 position:50% size:52% Notice that over here I can say, "Well, I'm going to change the horizontal, 00:07:38.458 --> 00:07:44.673 align:center line:-1 position:50% size:40% I'm going to zoom out, zoom in. 00:07:44.673 --> 00:07:49.469 align:center line:-1 position:50% size:41% I'm going to change the vertical." 00:07:49.469 --> 00:07:59.354 align:center line:-1 position:50% size:64% You can fully control the scope, bring images in, save and recall files, all doing that remotely. 00:07:59.354 --> 00:08:01.189 align:center line:-1 position:50% size:48% One thing I want to warn you about. 00:08:01.189 --> 00:08:06.820 align:center line:-1 position:50% size:58% When it comes to saving and recalling files, every scope is a little different. 00:08:06.820 --> 00:08:12.409 align:center line:-1 position:50% size:62% Since I know that engineers as well as engineering students hate to read manuals, 00:08:12.409 --> 00:08:16.121 align:center line:-1 position:50% size:47% if you're using a scope from a vendor other than Keysight, 00:08:16.121 --> 00:08:20.959 align:center line:-1 position:50% size:55% you may have to figure it out for yourself, but that shouldn't be too difficult. 00:08:20.959 --> 00:08:26.589 align:center line:-1 position:50% size:62% Remember, to download additional information about the fundamentals of oscilloscopes, 00:08:26.589 --> 00:08:30.301 align:center line:-1 position:50% size:48% go to the URL listed on your screen. 00:08:30.301 --> 00:08:34.973 align:center line:-1 position:50% size:48% Our next lesson will be our last one, at least for now. 00:08:34.973 --> 00:08:39.811 align:center line:-1 position:50% size:58% We will be talking about some important oscilloscope specifications. 00:08:39.811 --> 00:08:41.771 align:center line:-1 position:50% size:30% See you in Lesson 18. 00:08:41.771 --> 00:08:44.190 align:center line:-1 position:50% size:18% Go CU Buffs!
