Digilent Analog Discovery 2 is a USB oscilloscope, logic analyzer, and multi-function instrument that allows users to measure, visualize, generate, record, and control mixed-signal circuits of all kinds. (= 1/Period)(10MHz maximum), Period: The period of the waveform. For example, if you want to verify that the output from a pin of an integrated circuit is emitting a square wave, touch the oscilloscope probe to the pin and look at the display on the scope. Which closely matches what we measured when we simply counted the divisions. Click Run to apply this waveform to the Analog Discovery 2's W1 pin. It is the voltage axis. This will cause the two signals to be synchronized (both will start at the origin). Plug the Analog Discovery 2 into a computer with a microUSB cable and launch Waveforms. Analog Discovery 2 Quick-Start: Video 5 - Waveform Generator ToolKaitlyn Franz walks through the oscilloscope tool in WaveForms2015. It should move the waveform and the ground indicator up and down on the screen. 58 fairway drive hempstead ny; pros and cons of police reform; waste gasification plant cost. Connect the Wavegen output (Gnd) to the negative channel 1 input (1-) of the Scope. Using both the Supplies and Voltmeter controls see if you can generate a voltage using the positive supply and measure it using channel 1 of the voltmeter. I've got a question about the Analog Discovery 2: What is the maximum output current of Wavegen channels W1 and W2 to ground? The current horizontal position is indicated on the top edge of the graph, typically in the center of the display which represents 0 seconds. NOTE: Installing LabVIEW requires you create an NI account. Which will give you an Add measurement selection box like shown below. Use the cursors on the scope to measure the relative phase between two signals. There is only one common set of controls for all of the input channel. The horizontal controls are Position and Base which all contribute to how the incoming waveform is displayed on the horizontal/x-axis. You should now have something like the following. The data shown above was collected using the EEBoard's Power Supplies and Waveform Generator tools and the AD2's Voltmeter tool. Copyright Digilent Inc. Requirements software Waveforms Analog Discovery 2 A breadboard Two light-emitting diodes Some resistors some capacitors Some connection cables 2. These automatic measurements are only as good as the input waveform that you give them to do the calculations on. Notice, if you move the trigger level above or below the peaks of the waveform what happens? 4). I searched on the web for hours but I didn't look in the Help-Register on the Software. This tutorial will show you how to get started with the Analog Discovery 2 which will be used extensively throughout this course. The Analog Discovery 2 is equipped with two DC power supplies: 1 positive supply and 1 negative supply. It should also work with the other devices listed, but these haven't been tested. Phase: At what phase the waveform starts. Mode: - These are more advanced settings that will not be used in this course. You just never know when someone else has the same question and that way we can all learn and help each other get better. Leave all settings as defaults, and click the green arrow at the top of the window to play the wave. Wavegen I attach the VI that I have made to achieve this (testscope3.vi). Note: June 13, 2017.

It will start off by getting it connected to your computer and installing the required software. What I expect is that on each loop repetition the acquired signal would start in the same moment, but this is not the case. In this tutorial, we will not repeat them. If you have a version of this VIthat will run on the labviewhome bundle(2014) that would really help me out. The oscilloscope or scope is one of the most versatile and heavily used electronic measuring instruments in science, engineering, and industry. You can change the graphs y-axis scale (usually expressed in volts per division or VOLTS/DIV) using the Range dropdown box to control how the incoming voltage waveform is scaled when it is displayed on the graph. The measurements are updated at a certain refresh rate continuously. 3. I use Configure Digital Edge Trigger.vi to set up triggering. Below is an image showing the horizontal position of the display. By clicking on the Master Enable both supplies will then output the corresponding voltage for that supply on its designated output pins: (V+ and Gnd/) and (V- and Gnd/) for the positive and negative supplies respectively. | See terms and apply now Earn up to 5x points when you use your eBay Mastercard. Start the Waveforms software for the first time. The AD2 scope pins are fully differential, meaning that the +/- pins can swap orientation. With no options to decipher and set, you'll be up and running in no time. Yelp is a fun and easy way to find, recommend and talk about what's great and not so great in Graben-Neudorf and beyond. Anyone have any advice on how to do this? Condition: - This sets what type of edge you would like to trigger on: Either Rising, Falling or Both. Try changing the voltage and measuring again. rewrite in terms of sine and cosine calculator; area of triangle with 3 sides heron's formula Both my PCs are Windows 10 64-bit, I'm using exactly the same configuration in WaveForms 2015 Wavegen tabs, the board was calibrated using WaveForms on my dev. Figure 1: The WaveForms application This should bring up a new window. - Benchtop Oscilloscopes are available at Mouser Electronics. To download the necessary software to run Analog Discovery 2 on your PC/laptop, go to the website -. The only difference in functionality with the Voltmeter tool between the two Analog Discoverys and EEBoard is that the EEBoard has 4 voltmeter channels while the AD1 and AD2 only have 2. (= 1/Frequency). Connect the Analog Discovery 2 to the computer and to your breadboard like you have done in the previous labs. The Offset dropdown box or clicking and dragging the indicator will move this position indicator up and down on the display which in turn will also move the incoming voltage waveform up and down on the display. There are two main areas: tool options are at the top, and then the voltmeter channels take up the bulk of the window space. Both power supplies should currently be disabled as the Master Enable is Off. Note For example, If you are trying to obtain a voltage measurement and the signal is either really tiny on the screen or way to big for the screen (part of the waveform goes off the top of the display) the calculation will be made but could be incorrect. Level: - This control sets at what voltage the incoming signal (ie. The higher the incoming voltage, the farther from the ground (0 Volt level) the graph moves for a given Range setting. The Voltmeter window will open. The "+" pin would then connect to the side of the element where you expect the higher voltage to be. "File" lets you Save the current Voltmeter project, Open a saved project, Export the current window data, or Close the Voltmeter tool window. Open the 'Waveforms' program and make sure that it successfully connected to your Analog Discovery 2. As the number of divisions dont always work out so nicely as the example, you can either use the X Cursors tool located in the top toolbar or the Quick Measure tool Im going to show here to make a quicker more accurate measurement. Using the Wavegen tab of Waveforms, set up the following waveform on channel 1: This is 5V peak-to-peak square wave (note that the amplitude setting is for peak voltage) with a two second period. As always, thanks for reading. There is one set of controls for every input channel. Tips To connect the test probes, make sure you pushed the black bar all the way in. (Analog Discovery) 2 . Select the Wavegen tool from the left-side menu and you should get a new tab that looks like the following. If the signal is inverted from what you expected, be sure you have the "-" pin connected to the side of the element where you expect the lower voltage to be. Open the Scope tab. Download the appropriate files suited to the Operating System of your PC or Laptop as shown in Fig. You need at least five harmonics to compute a valid thd figure. Click the "Wavegen" option to access the function generator and enter the following parameters: Type: Sine Frequency: 5kHz Amplitude: 1V Offset: 0V Symmetry: 50% Phase: 0 degrees Each acquisition starts at an arbitrary moment and the signal moves visibly along the time axis. Using the Wavegen tool create 2 Sine waveforms both at 1kHz and 1VPeak with a phase shift from one another so we can learn how to measure the phase difference between those waveforms on the Scope. LTspice timing diagram of counters 2. All of the controls on the Scope have no effect on the incoming voltage it only effects the way the waveform is displayed on the screen. There is also a Tracking checkbox, when this is enabled the positive and negative voltage will always have the same absolute value. The Digilent Analog Discovery 2, developed in conjunction with Analog Devices, is a multi-function instrument that allows users to measure, visualize, generate, record, and control mixed signal analogue and digital circuits. To measure the phase difference between these 2 waveforms in time we can easily approximate this by counting the horizontal divisions from where the yellow crosses the 0V level to where the blue cross the 0V level. To use the Voltmeter tool on the EEBoard, use the oscilloscope pins located in the SCOPE block. This means that any voltage readings will be in reference to the circuit GND. Once it is running the Run button becomes the Stop button. I've got a question about the Analog Discovery 2: What is the maximum output current of Wavegen channels W1 and W2 to ground? In the top toolbar in the dropdown to the right of the Channels dropdown you also need to select Synchronized as shown below. To activate the tool simple double click anywhere on the Scopes waveform display and your cursor will become a vertical red bar you can move around the display like the one shown below. The Analog Discovery 2 is equipped with 2 voltmeters: Channel 1 and Channel 2. When you move the red cursor left and right on the display it will tell you the instantaneous voltage of both channels at the specific time that you have the cursor. When measuring the phase in time between two waveforms it is important to measure the time starting with the reference waveform to the waveform under test to obtain the correct sign. - a computer with USB port to run the software. Mouser - , . Create a peak to peak voltage measurement for Channel 1 using the steps outlined above. If everything is connected and installed correctly you should notice the device and serial number (SN:) in the bottom corner as well as the devices status (OK). By clicking on the Run button both voltmeters will then display the corresponding voltage that is currently measuring on its input pins: (1+ and 1-) and (2+ and 2-) for Channel 1 and Channel 2 respectively. Knowing that the frequency of this waveform is 1kHz, the period is 1000us. To add a measurement use the Add dropdown and select Define Measurement. Make a change to Range dropdown box and see result. In the VIs there is nosuch run/repeat option. Adjust the trigger controls to see how the effect the Scopes graph display. Even the the stop button won't stop the VI, I have to kill LabVIEW from the process manager. Once the first acquisition is finished it will then wait for another trigger signal to start the next one.

To control the output voltage of the supply you can either use the drop down to select a voltage, type the number to 3 decimal places or use the slider. You will learn what the difference of these readings are later in this course. PC and all the calibration values are the same on both PCs (which is not surprising as these values are stored in board's EEPROM). If I now display the voltage on the oscilloscope, the curve is cut off at around 4.6V. Analog Discovery 2 USB Oscilloscope Software WaveForms version 2.6.2 or later LabVIEW (versions 2013 and 2014 have been tested to work so far) LabView Run-Time Engine 2105 (This is an optional alternative for the LabVIEW editor, see next step for details.) In WaveForms you have selected "Auto sync" which sets Run time equal to signal period, and this restarts/generates trigger signal for each period. If I now display the voltage on the oscilloscope, the curve is cut off at around 4.6V. You can then add measurements that will be automatically calculated from the waveform that is captured on the Scopes graph. Type: The type of waveform (Sine, Square, Triangle etc), Frequency: The frequency of the waveform. So it can be reproduced byliterally just unplugging and re-plugging the USB cable from one PC to another. Return the position back to the center of the display by setting the offset to 0V.
