In this lab we will learn how to use tools such as the function generator and the oscilloscope. We will also learn the basics to reading datsheets and schematics.

Reproduce each of the following figures as closely as possible, and include a screenshot in your write up. Don't forget to include the measurements and cursors. Some of the input signals have introduced an offset.

If you are using the Tektronix TDS 3012B and it has an ethernet connection, you can easily take screenshots of the display. Simply type the IP address of the oscilloscope into your computer's web browser, and it will connect to the scope's web interface. If you don't know the IP address of your scope, restart it. The 3012B will display its current address during it's start up sequence. Once you're connected to the scope from your web browser, you may save the image of the current display or control it through the web interface.

By default, the oscilloscope acquires the signal with a very rough sampling process. If you wish to improve the quality of your display you may change the Acquisition Mode. You may do this by going to Quick Menu -> Acquire Mode then changing the mode. Averaging several samples will give you a much smoother looking result.

Now we will measure a couple signals directly on the ELEC226 board and learn how to read a schematic. Download lab1_2_lite.hzx . Open CrossStudio Release 1.3, and set your target as the MSP430 USB CrossConnect. You can do this by clicking on View -> Targets . The Targets window should open up on the right panel. Right click on MSP430 USB CrossConnect and select Connect . You may download the project file to the MSP by selecting Download File -> Download CrossWorks Executable File and navigating to the desired file.

Now locate the two high frequency crystal oscillators. They are small silver cylinders. Directly probe the two oscillators, and measure their respective frequencies. Next, using the schematic locate the pin that outputs SMCLK or MCLK . (Use the pin on Port 5.) This is currently configured to output one of the oscillators. Probe this pin and compare with the results that you obtained probing the oscillators directly. Next, using the schematic locate the output pins for DAC0 . Measure the peak-to-peak amplitude, and frequency of the signal and include a screenshot.

Next, we will run a couple signals from the function generator through the board's Analog to Digital Converters (ADC) and measure it a couple different places. Download lab1_3_lite.hzx . Download the file like you did in Problem 2. Set your function generator to produce a signal less than 2 kHz. Connect it to the input of A1 , analog input 1, and measure the signal at the output of DAC0 . Try to recreate the following figure.

Sine wave through ADC and DAC
What happens are you increase the frequency or amplitude of the input signal? At what frequency does the signal very become skewed?

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help

Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
