Set the Power Supply current limit to just above the amount of current you calculate you need. Do not turn on the power supply until you have rechecked your circuit for correct wiring Do not allow the test leads connected to the power supply to touch each other! National Instruments' ELVIS II+ Series Hardware NI ELVIS II Series combines hardware and software into one complete laboratory suite. The system consists of an independent computer running a version of Microsoft Windows XP (or later), an USB cable ECE 206 Page 2 of 14 to the ELVIS II+ Workstation equipped with the ELVIS II series prototyping board, and an AC/DC power supply.

You can build circuits on the prototyping board and later analyze them with the NI ELVIS II+ software instruments or independent instruments. General The circuit development process begins with a need for a product or service. This need is recorded as a concept in a concept document. The concept is then formalized into an accomplishable set of requirements. The requirements document is used to develop the design that will meet the requirements. The design is first tested using circuit simulation. The simulations help with understanding the interaction of the various parts used in the design. The electronic parts' values and tolerances can be estimated. Once the simulation is complete, the circuit can be constructed with actual, physical devices on a prototyping board were measurements can be made to verify the simulations and determine if any issues arise that the simulation models didn't illustrate. The Educational Laboratory Virtual Instrumentation Suite, ELVIS II+, is a system that delivers hands-on lab experience with an integrated suite of more than 12 of the most commonly used instruments in one compact form factor. It includes a two channel, 100 Ms/S (20 MHz) oscilloscope; digital multimeter; function generator; dual output(+12V & -12V), variable power supply; three output (+15V, -15V, +5), fixed power supply; a RLC Meter, and a Bode analyzer. Software Front Panels Used in this Lab This lab exercise requires the following SFP (Software Instruments) 1. Digital Ohmmeter on the DMM [2, Ohms] 2. Digital Capacitance Meter on the DMM [F, Faradays] 3. Digital Inductance Meter on the DMM [H, Henries] 4. Digital Current Meter on the DMM [A, Amperes] 5. Digital Voltmeter on the DMM [V, Volts] Components Used in this Lab This lab exercise requires the following components: 1. 1.0 k resistor, R1 (brown, black, red) or closest available 2. 2.2k resistor, R2 (red, red, red) or closest available 3. 1.0 MQ resistor, R3 (brown, black, green) or closest available 4. 1 μµF capacitor, C or closest available 5. 5 unknown resistors (from Resistor Bin) 6. 1 inductor of any milli-henrys value Exercise 1: Measuring Component Values Complete the following steps to measure component's electrical values: ECE 206 Page 5 of 14 1. The first step for all experiments is to calculate what measured values you expect to get, the expected values, by using the measured values of the components and the power supplies. If you obtain measured values close to the expected values then the circuits were built correctly and the measurements were performed correctly. If not, then track down the source of the error(s) and correct them. It can be misunderstanding of the circuit, incorrect expected values, poor measurements, incorrect part values, or other issues. 2. Turn on the ELVIS II+ power switch. See Fig 5.
