An On Page Connector behaves like a wire those with the same name are electrically connected so get another connector and in the window that appears double-click on the name that you chose earlier and put the connector near the positive side of the AC source as shown below. Vin) and place it somewhere so you can connect it to the positive side of the channel A of the oscilloscope. In the box that appears name the connector something useful (e.g.

If the wiring is messy you can use an On Page Connector (in this circuit it might be overkill but it will be useful later), to use the On Page Connector go to Place-> Connectors-> On Page Connector (or Ctrl+Alt+O). Notice that when two wires simply pass over each other there is no connection (inside the yellow circle) but where the wires are actually connected the connection is represented by a dot. After placing the oscilloscope and wiring it to the input and output terminals it should look like (without the yellow circle): Channel 1 is normally used to look at the input of the circuit, and channel 2 is used for the output. So click on the one that is simply called вЂњOscilloscopeвЂќ and stick it in your favorite spot on the board. You have four choices for most circuits the generic 2-channel oscilloscope does the job. Now choose an oscilloscope from the right hand toolbar (the Instruments toolbar). To connect a wire to a component you only need to click once near the red dot however to leave it loose you need to double click (the red dot is visible in the picture above.) A quick way to make sure a connection exist is by dragging the component and seeing whether the wire comes along. You might be afraid that the connection has not been made since MultiSim does not really show a connection but as long as you click on the red dot that appears near the terminals the connection will be made. If you need to make multiple connections at the same point you can add a Junction by going to Place-> Junction (Ctrl+J). Wire the circuit by clicking on the end points of the components (do not worry about the вЂњ1вЂќ and вЂњ2вЂќвЂ™s written on the ends of the components). Up to now you must have something like this: Place the resistor and make sure it is the right value if it is not, double click it and change the value. (If you donвЂ™t see a toolbar with 9 blue buttons, right click any of the toolbars and check that вЂњVirtualвЂќ is on.) Click on the вЂњBasicвЂќ group (with a resistor icon) and choose вЂњPlace Virtual ResistorвЂќ (notice that you could have found the capacitor in the same place). Metric prefixes (or their one-letter abbreviations) can be typed in the box along with the number.ДЇor the resistor letвЂ™s use the Virtual Toolbar (shown below) to quicken the process. You can either select the correct valued capacitor from the list or place one and double-click it and modify the value. The ground is one of the most important components in every Multisim circuit: the mathematics of SPICE requires every circuit have a power source and a ground, or else nothing will work! Next find the capacitor, in the вЂњBasicвЂќ group. Now place the ground (hint: look in the вЂњPower SourcesвЂќ family). Rotate components with Ctrl+R flip them with Alt+X and Alt+Y. Components, and the associated labels, can be dragged after placement. Choose an appropriate spot and click to place the component. A ghost component is now pinned to the cursor. The AC source is in the вЂњSourcesвЂќ group (top left), вЂњSignal Voltage SourcesвЂќ family and is called вЂњAC VoltageвЂќ select it and click on OK. There are a few ways: Place -> Components ( Ctrl + W) or right-click a blank spot and go to Place Component. Create a new file with File-> New-> Design.ДЇirst we need to find the components. Open Multisim by clicking on Start -> Programs -> National Instruments -> Circuit Design Suite 11.0 -> Multisim 11.0. LetвЂ™s try the following RC high-pass filter: You do not need this but you can use it if you want for any final work.

Note: There is a Printed Circuit Board (PCB) program called Ultiboard 11.0 for permanent Board work available. You will learn to draw and test circuits in Multisim. Almost any circuit can be modeled in Multisim, and the model can be tested using MultisimвЂ™s virtual lab bench which includes oscilloscopes, function generators, etc. SPICE itself is extremely difficult to learn and use, so programs such as Multisim provide an intuitive front end for the powerful SPICE engine. SPICE is the industry standard circuit simulation engine, developed here at Berkeley.
