    1. Benefit of Using NI Circuits Teaching Solution<\/h3>\n

    Traditionally, circuit theory is taught using three different tools: textbooks and lecture, software simulation, and breadboarding and testing in the laboratory. \u00a0With no correlation between the tools, students often struggle to transition from the classroom to the lab, and from theory to implementation. \u00a0This ‘siloing’ or ‘isolating’ of each phase in the learning process today inhibits students from gaining the experience they needs to be successful engineers and scientists of tomorrow.<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    The NI circuits teaching solution is the complete platform of software, hardware, and courseware for educators to build student expertise through practical hands-on experimentation with electrical circuits. The solution connects theory directly to real components in simulation and integrates physical analysis immediately in experimentation. The NI circuits teaching solution includes the NI Multisim circuit teaching software which enables learning through an intuitive, pedagogical user environment to define circuit diagrams wich simulation powered by industry-standard SPICE technology. The other component of the solution is the NI ELVIS modular engineering education laboratory platform which combines a rugged, laboratory optimized form factor with 12 measurements instruments powered by industry-standard LabVIEW technology. Students are able to gain a strong circuit theory foundation using pedagogical tools developed for academia, but based on the same technology they will use in their engineering careers.<\/p>\n

    3. Step 1. Create a Circuit in NI Multisim<\/h3>\n

    The below image shows a circuit designed in Multisim:<\/p>\n

    \"\"<\/p>\n

    Note<\/b>: Skip ahead to Step 3 if you want to build the circuit first. Also, ensure that your NI ELVIS II device is connected to your computer and detected before launching Multisim if you want to compare simulated data to real data in the same sitting. Multisim checks for all connected NI devices at launch time. You have to close and reopen Multisim to detect newly connected devices.<\/p>\n

    1. Launch Multisim by navigating to Start\u00bbAll Programs\u00bbNational Instruments\u00bbCircuit Design Suite\u00bbMultisim.<\/b><\/p>\n


    \n\"\"<\/b>\u00a0<\/b><\/p>\n

     <\/p>\n

    2. Create a new NI ELVIS II or NI myDAQ design (this example uses an NI ELVIS II design) by navigating to File\u00bbNew\u00bbNI ELVIS II Design<\/b>.
    \n\"\"<\/p>\n

    3. Observe the schematic.\u00a0The NI ELVIS II device features connectors for all terminals, so you can fully simulate the hardware instrumentation within the virtual environment.<\/p>\n

    \"\"
    \n4. Place the desired operational amplifier for the filter (this example uses a 324) by right-clicking Place component<\/b>.
    \n\"\"
    \nSelect the following parameters in the Select a Component<\/b> dialog box:
    \nDatabase: <\/b>Master Database
    \nGroup:<\/b> Analog
    \nFamily:<\/b> OPAMP
    \nComponent:<\/b> LM324N
    \n\"\"
    \nClick OK<\/b> to select the component and return to the schematic to place the component.<\/b><\/p>\n

     <\/p>\n

    5. Left-click to place the LM324 operational amplifier on the schematic. Choose A<\/b> from the pop-up window to select a Type A amplifier.
    \n\"\"
    \n6. When the Select a Component<\/b> dialog box reappears, you place the next component. Next, place the 220 nF capacitors.<\/p>\n

    Select the following parameters in the Select a Component<\/b> dialog box:
    \nDatabase: <\/b>Master Database
    \nGroup:<\/b> Basic
    \nFamily:<\/b> CAPACITOR
    \nComponent:<\/b> 220n
    \n\"\"
    \n7. Click OK<\/b> to return to the schematic and left-click to place the capacitor on the schematic. Repeat for the second capacitor.
    \n\"\"
    \n8. \u00a0Next, place the 10 k\u03a9 and 2 k\u03a9 resistors.<\/p>\n

    Select the following parameters in the Select a Component<\/b> dialog box:
    \nDatabase: <\/b>Master Database
    \nGroup:<\/b> Basic
    \nFamily:<\/b> RESISTOR
    \nComponent:<\/b> 10k, 2k
    \n\"\"
    \n9. \u00a0Select OK<\/b> to return to the schematic and left-click to place the resistors.
    \n\"\"
    \n10. The resistor is horizontal, but it needs to be vertical. Select the resistor and press <Ctrl-R><\/b> to rotate the resistor 90 degrees.
    \n\"\"<\/p>\n

    11. Use On-page<\/b> connectors<\/b> to supply power to the operational amplifier in a tidy fashion rather than having to wire from the +15 V and -15 V rails of the virtual NI ELVIS II directly.\u00a0Navigate to Place\u00bbConnectors\u00bbOn-page connector<\/b>.<\/p>\n

    \"\"<\/p>\n

    12. Left-click to place the connector near the NI ELVIS II virtual terminal for DC power. The following dialog box appears. Select +15 for the first connector and -15 for the second connector.<\/p>\n

    \"\"
    \n13. Wire the On-board connectors<\/b> to the DC power rails.
    \n\"\"<\/p>\n

    14. Place and wire On-board connectors<\/b> for providing power to the operational amplifier above and below pins 4 and 11, respectively.<\/p>\n

    \"\"<\/p>\n

    15. Complete the circuit by wiring the components together. The NI<\/b> ELVIS II Function Generator <\/b>is the input signal to the filter, and you provide a 2 k\u03a9 load for the output to ground. Connect the NI ELVIS II Bode Analyzer<\/b> to the circuit to observe the source voltage and the output voltage after being filtered.<\/p>\n

    \"\"<\/p>\n

    The circuit is now complete. The next section explains how to perform a Bode analysis in Multisim by simulating the NI ELVIS II hardware and observing the behavior.<\/p>\n

    Note:<\/b> The circuit is connected to Scope 0<\/b> and Scope 1<\/b>, as well as Analog Input 0<\/b> and Analog Input 1,<\/b> because the simulated NI ELVIS II device uses the oscilloscope instrument, and you connect the physical circuit to analog inputs. You can use the oscilloscope channels for the physical test, but this requires splitting a BNC cable to a Ground and Signal pair.<\/p>\n

    Back to Top<\/a><\/p>\n

     <\/p>\n

    4. Step 2. Simulate NI ELVIS II Instrumentation for Bode Analysis<\/h3>\n

    1. To perform a sine wave frequency sweep of the filter, you first need to enable the function generator. Double-click the NI ELVIS II Function Generator<\/b> to enable the virtual instrument and launch the Soft Front Panel<\/b>.<\/p>\n

    \"\"<\/p>\n

    2. The NI ELVIS II Function Generator<\/b> is now enabled, and you may close the Soft Front Panel<\/b> window. The function generator remains enabled.<\/p>\n

    \"\"
    \n3. Next, you must enable the NI ELVIS II Bode Analyzer<\/b>. In the same fashion, locate and double-click the Bode Analyzer<\/b> to enable the instrument.<\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    4. The NI ELVIS II Bode Analyzer<\/b> is now enabled.
    \n\"\"
    \nBefore simulating, you need to verify that all of the settings are correct. Modify the Start Frequency<\/b>, Stop Frequency<\/b>, and Steps (per decade<\/b>) if necessary. Leave the Device<\/b> as Simulate NI ELVIS II<\/b> for now because you first want to simulate the device.<\/p>\n

     <\/p>\n

    5. Select the Simulate<\/b> button in the Multisim toolbar to simulate the frequency sweep and observe the resulting voltage, which is a Bode analysis.
    \n\"\"
    \n6. The following image shows the resulting simulated data from the Bode analysis of an active highpass RC filter.
    \n\"\"
    \nYou are now ready to build the active RC highpass filter circuit on the NI ELVIS II prototyping board to compare the circuit to simulated data.<\/p>\n

    Back to Top<\/a><\/p>\n

     <\/p>\n

    5. Step 3. Build a Circuit on the NI ELVIS II Prototyping Board and Acquire Real Data<\/h3>\n

    1. The Multisim design generates the following Bill of Materials. You can find this in Multisim by navigating to Tools\u00bbBill of Materials.<\/b><\/p>\n

     <\/p>\n\n\n\n\n\n\n\n
    Quantity<\/b><\/td>\nDescription<\/b><\/td>\n<\/tr>\n
    2<\/td>\nCapacitor, 220 nF<\/td>\n<\/tr>\n
    2<\/td>\nResistor, 10 k\u03a9<\/td>\n<\/tr>\n
    1<\/td>\nResistor, 2 k\u03a9<\/td>\n<\/tr>\n
    1<\/td>\nOperational Amplifier, LM324A or similar<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

     <\/p>\n

    2. The next step is to properly place the components on the NI ELVIS II prototyping board. If you are new to connecting components and wires to a breadboard, use the 3D breadboard tool in Multisim by navigating to Tools\u00bbView Breadboard<\/b>.<\/p>\n

    \"\"<\/p>\n

    This is the 3D view of the NI ELVIS II prototyping board in Multisim. With it, you can virtually lay out the circuit properly on a breadboard. This functionality is further explained in the Related Links section document NI Multisim 3D Environment.<\/a><\/p>\n

     <\/p>\n

    \"\"<\/p>\n

    3.\u00a0After physically building the circuit, you need to ensure that your NI ELVIS II device is connected to your computer via USB and is detected by your computer. In addition, the main power and the prototyping board power should be turned on. If you experience any trouble with this, refer to the Related Links document Where to Start With NI ELVIS II Series<\/a>.<\/p>\n

    4. In the Multisim environment, you can now choose to acquire data from your NI ELVIS II device. Open the NI ELVIS II Bode Analyzer<\/b> in Multisim. You should still see the simulated data on the Bode analyzer. If you do not, resimulate the Bode analysis as shown in Step 2.<\/p>\n

    5. Select Dev# (NI ELVIS II) or Dev# (NI ELVIS II+), depending on which device you have connected. This is your physical device. Next, Multisim uses the physical instrumentation form of your NI ELVIS II device to generate and acquire data from the active RC highpass filter that is constructed on the prototyping board.<\/p>\n

    Note:<\/b> If your NI ELVIS II device does not appear in this list, save your Multisim file and then close and reopen the program. This repopulates the list of active NI devices on your system.<\/p>\n

    \"\"<\/p>\n

    6. Before running the program, ensure that you select the proper Stimulus<\/b> and Response<\/b> channels for the Bode analysis. To begin the analysis, click the green Run<\/b> button on the NI ELVISmx Bode Analyzer<\/b> window.<\/p>\n

     <\/p>\n

    \"\"<\/p>\n

     <\/p>\n

    7. You can now see the actual circuits response in comparison to the simulated response, on the same graph, and without ever having to leave the Multisim environment.<\/p>\n
