Physics 434 Welcome Leslie Rosenberg [prof] Scott Davis [TA] Thanks to Toby Burnett [prof] (for much of the course material) Jason Alferness [Equipment] David Pengra [consultant] Mac Stetzer [education coordinator]

Preliminaries class schedule. Lab room can often be made available The text book (new edition), home versions of the program –Windows and Mac –We will lend DVDs with a Linux version Grading (lab reports/homework, project) –2-person collaborations, same grade to each –The lab “report” is the VI: Documentation (under properties) –Intro, discussion, conclusions Save graphs with VI (operate | make current values default) Comments in the diagrams, well-labeled front panel We’ll try using Catalyst tool CollectIt for turn-in of assignments. Project –Individual, or collaboration with clearly separate parts

Course objectives Basic tasks involved in experiment –Control –Acquisition –Analysis Will practice using LabVIEW for all three tasks. Why LabView…what else is there? Do you need to know electronics and physics: a little Computer interfacing: mostly just understand and use the NI board and break-out-box. (The project another story…it can be more complicated.)

Brief Schedule ClassTopic 1Intro to LabVIEW 2,3Module 1: voltage vs. current 4Module 2: Digitial I/O 5Module 3: Kundt’s tube, resonance fit 6,7Module 4: Kundt’s Tube, impulse 8Module 5: GPIB multimeter 9, 10Project

Explore the interface: Getting Started Activity Start LabVIEW, look under Resources Open “Getting Started with LabVIEW” Read and follow the instructions in Chapter 1 until “Adding a Control to the Front Panel”

Tools palette Automatic tool selection OperatePosition /size/select Edit Text Wiring toolObject short cut menu Scroll BreakpointProbeGet Color Set color Shift-right click View | Tools Palette

A quick exercise Blank VI Right click on Panel Select a numeric control (knob?) Click on panel to install it Right click again, select numeric indicator, install Open wiring Diagram (cntrl-E or Window | show block Diagram) Use wiring tool to connect them (see how the cursur changes? Run continuously

Simple exercise, continued Add a while loop on diagram (need the Functions Palette: show it, or right-click) –Right-click on input to the condition terminal, select “create control” a stop button just appears! Now just run. Try highlight execution (the light-bulb), probe (mouse near a wire) Turn on the context help (cntrl-H), try tiling the windows (cntrl-T) Add a second indicator, wire it in. Use the labeling and color tools Don’t forget the very important keys: cntrl-Z and Esc

If time… Continue with tutorial, start other activities, read the text and look at the assignment
