213 is a digital storage oscilloscope, small and portable. Its characteristics are: it has two analog inputs, two analog channels, and two digital channels. Here, the maximum sampling rate is 100 mega samples per second. Just remember, the sample rate is how many measurements are taken per second. And it has a 15 mega analog bandwidth. The bandwidth is the maximum frequency of an input signal which can be scanned with minimal amplitude loss. Anyway, I usually recommend at least 10 to 20, 30 samples per cycle. The maximum input voltage is 40 volt peak-to-peak. It includes a waveform generator through this output, and the screen is 3 inches with a resolution of 400 by 240 pixels. Here, do you have the USB? The USB is for charging the batteries, downloading files, and firmware updates. And here you have the power switch. Okay, there for inputs are ports MZX username GX connector, so are like this one. But if you are going to use the normal BNC connectors, you have this kind of converter, so you could use like this one, connect it, and that's all. Okay, okay, let's switch on it, and the first thing that you see are several lines. Okay, so let's see what we have on the screen. The first thing I want to show you is the is the grid. I don't know if you could notice that, okay, there are lines, okay, it's a grid, okay. That grid will help to measure time and and voltage. Okay, you have these four lines, okay, well, they are two overlapped. The first, the first one, let me move this one up so you could see it better. Okay, do you have a in blue is channel A, being yellow channel B, channel C in purple, and channel D in green? Okay, these two channels are analog, and these two are digital. Okay, also you could see here a line in the middle. This one is the trigger point, the trigger, the trigger level, okay, and this is the zero time. Okay, you could see you have many things around, and you could move around all these using these buttons. So let me explain you about these buttons. These buttons at the top are called K1, K2, K3, and K4, okay, so I will refer like that, and you could see at the top of the screen what each of the keys does. But just this is a round pulse, so in what you, it is running, scanning. If you click it, pause. Okay, this one goes to display menu. It is a general menu that you could see have different options. These are for saving and loading files. This is to save that file, to load that file. We will see later for what purpose. Say the buffer and save CSV format to be read in Excel, for example. The volume, you could set the volume of the when you push the buttons. The LCD backlight, you could reduce it or increase to see it better or save some battery, and the amount of time before powers down. Fragment is by default K3 to confirm. So if you are going to save something, just K3. So 1, 2, 3 to save, and you see, okay, completed. Okay, the next one is this one, the K3. This helps to switch between channels. We will see later. And okay, we click here, so the menu disappear. And this one, this one will say FN combination key. So if you hold it and move in colors, they will move faster, and we will see the color for what purpose. If you click here and here at the same time, it takes a snapshot, save image. Okay, if you click here and click here to save the system settings, and if you click here and here at the same time, you go into auto calibration. Okay, then we have the they will A and will B, also called in colors. Will A is put jaw just and or change an option. For example, we have here I Y P is to move this in the Y axis, so you see it is changing. And this one A B, the B will is to move through the different options to see this blinking and going to other options. Okay, so that's all.
Okay, let's go now to the parameters area that is at the top. Okay, you could see here in the parameters area that you could access to different things. In order to see that properly, I will connect this one so we could see a waveform. Okay, we have a waveform, and the first thing we have to change the frequency, okay, and the trigger. Okay, that's all.
Okay, so let's go here and what we have first of all is that this one is battery. This one is to the status, so it is running or stop. If you click here, hold. Okay, this one is channel A, channel B, channel C, and channel D. Channel A, this is a coupling, so you could go to the coupling and change that between DC, AC, or disable the channel. Okay, and you could change the voltage, the amplitude. So it is the this is the distance between one they told consecutive lines of the grid. Okay, so from here to here you have 1 volt. So you could increase or decrease. If you increase it, reduce it. If you decrease, okay, it starts blinking because the the trigger is the trigger line is out of the function. Okay, you have to put the trigger line in the middle of the function, otherwise it will not stop. Okay, so we have this one. Then we could go to other channel. Let's say if we connect just something in the second channel, okay, and we have a square function there. Okay, let's see what we could do. The first thing is that we could change the value as I mentioned, DC, and let's say, okay, I could put it, I will put it in two volts and okay. Then what you could do is channel C, channel C, you could do several things, or just show why is going through the channel C, or do calculation between channels A or channels B, or do operational their operations between Chelsea and the the inputs. So if you change this to just get A plus B, you see the purple one is A plus B, or A minus B. You could move these functions. Okay, we will see later how C plus D, there, C and D, pull the operation. There is nothing in C and D, so or do anything else. Okay, let's see, for example, that I put just channel C, and they will take these ones. It is a digital input. I will put it here, okay, and I will put another digital signal here. Okay, so we have these two. Now I could go to C, you see, and I could say, okay, want operations between these two, but I will not see this anymore. Okay, so let's say that it is C and D, so this is the operation, the AND operation between this and this, so you get that one. C or D, inverse A, inverse B, and that's all.
Next one, channel D. Channel D, you could have channel D, that is the green, or you could also do some operations as you could see here with with saved information and a memory. So let's say that, for example, imagine that you go to the menu, okay, and you save in these five, okay, so you just save, it is completed, and you back. You go in channel D and say, okay, I want to show what is recorded in channel A. You do not see anything, but if you go to the menu again, and you go to load, sorry, now it was the fifth one, complete, and you have it there. Okay, so this is what it's recorded from channel A. You could then change channel A and do whatever you want, like change the function, and you see you have the previous one. So, okay, let's continue.
Next one is the X position. It is just the position to see other functions that are recorded or are there as kind. More things, you go here, and you have the trigger. So this one defines where the trigger is. So in the, let's go to the trigger mister. So if we move it, you see the blue line is going up or going down. This is for channel, the channel A, but you could change channels. So you could say, okay, don't want to trigger based on this channel, I want to trigger based on another channel. So for example, let's take this one and put it here. Okay, so or instead of this one, of this is a square one, now it's okay, it's okay, this one. So I want to triggering a set of based on this blue one, I want to trigger based on the yellow one. So you just click here and you change it. It will change from blue to yellow, you see. So now this is the trigger, and and you could have the line in a different position. Okay, so you could have the trigger here. I need to come back or do you just change through the different channels when you see the line there. So you could go like saying, okay, I'm going to trigger based on this channel or based on the solar yellow, purple, green.
Next one is the edge. Okay, and as you could see at the top left of the screen, there are different kind of of triggers. It's not only falling or rising. There also you could have the smaller than trigger, larger than trigger. So if something happened over that or below that. Okay, if also you have fun negative poles with that is larger than the trigger or positive poles that is larger than the trigger, and so on. So you just could play with with that. But usually you use the default in a rising edge. Here you have the mode of of the trigger. Useful, you have it in auto, but you could have in normal, single. So will happen whenever it happens, the trigger condition, it will just hold and stop. You have to start the game every time until the new condition happened. So it is good to just keep something that happened very rarely from time to time. Okay, also you have this slow and out.
Next one is this is the time base. So is the distance in time between two vertical lines in the grid. Okay, so it is 200 microseconds from here to here. So here to here you have 400 microseconds, and from here to here, we will see later how to calculate that. Okay, so if you change that value, it will just let me see it should, okay, it's an hold. Okay, so it should, okay, it should zoom or expand. Okay, you see.
The next one is the function generator. You could generate if a square function, a sine function, triangular, or sawtooth. You will not see the function here, you only see a representation of that. They're all the functions are three volts peak-to-peak generated. And the square function, you generate it between 10 kilohertz and 8 megahertz. And add a triangle, are you see same general sawtooth. And if you go to the next one is the frequency. So you could go with the rest, they sinusoidal, ephemeral, shuttles between 10 hertz and 20 kilohertz.
Now I will jump to the bottom of the screen. So this area at the bottom of the screen, later I will explain. Raises these are measures. Okay, so what kind of measures we have there? Well, here we have measures about time, and here measures about voltage. So here measures about Y axis, and here measures about X axis. So sorry, X and Y, X axis and Y axis, time and voltage. Okay, what kind of values? Okay, let's cut there. The first thing is that you could change, do you want to measure something? So you could change. Now you are measuring the frequency of the yellow channel. So this the B channel, but if you change, you click here to change the channel. Okay, so now is the channel C, channel D, channel A, again B, C, D, A. Okay, I will take this one because it has a different frequency and I will put it here. Okay, and you see here that you have 1 about 1 kilohertz in the blue one, and if you click here, you have 3 kilohertz. Okay, it's the frequency I'm generating from a function generator. So let's see what other values do we have here apart from frequencies. You could have the TT, you could have, I will explain this one later. These are different values like the this one is the high level time of single cycle, this one is the low level time of single cycle. So the distance between here to here, it is 200, 60, and this one is about 70 microseconds. And also you have this cycle, that is the single cycle, and the frequency as before. So you could just go and do here the same. So you could change whatever for any function. So you could have different values of the same function or of different functions. Okay, let's see this one. As I mentioned before, you will have that in any of them. This is increment of time. This is the distance between two markers. Time is these axis. So between T1 and T2, how we activate these markers? You could go here to T1, okay, and if you want to see it, you just click this button, the key, the K3, and you see it. Okay, you see it activate or deactivate. Okay, and then you go to this other one and you activate it again, and now you have these two lines. So this is the distance between here and here. Okay, so you could say, okay, T2, I will move T2, so I just moved it to wherever you want, and for example, here, and I go to T1 and move T1 from, for example, here. So the distance between this and this one is 260 microseconds. Okay.
Okay, let's see this order. This order are related to voltage. Okay, so you could have the same to be, but as this is related to voltage, this is only valid for the analysis. So A and B, A and B, not C, okay, because you are de done. Okay, so here you have this pulse big peak. You could have different values like volts or RMS. You could have both a bridge and this increment in voltage rules later, and they both of the trigger, the bonds of the battery, and the maximum voltage, minimum voltage. Okay, so what is this? This is the same as before. So is the distance between these two markers. So I go here, okay, and say, okay, activate V1, I see the line, and activate V2, okay, you see the line, and I want to move V2. So I could measure like, for example, the distance between the bottom of the function and the top of the function, and I see that this is about 5.5 volts more or less. Okay, so this is for that purpose. And in the last one, we could have also this the same thing or different things in different, different functions. Okay, so that's all. It's a very nice oscilloscope, very handy, a small board ball, so nice, nice thing. Thanks for watching.
