3) In the display to the right we can see that
our 200 mVpp sinewave now has a
minimum value near 0 V (-400 uV = -0.4
mV), and a maximum value of 200.3 mVpp.
Note the ground symbol on the display.
4) Remove the 100 mV DC offset using the
Knob. Our sinewave is still 200 mVpp.
5) Method 2: Press the Offset softkey, to select LoLevel. Raise this to 0.00 V. Now, press the
"HiLevel" softkey, and use the Knob to raise the high level to 200 mV. This accomplishes
the same result: a 200 mVpp sinewave, that goes between 0 V and 200 mV.
6) Press the Graph hardkey; you can see the waveform you have just created, and can modify
the frequency, amplitude and DC offset using the yellow, purple and blue softkeys
respectively. Try it. When you are done, press the Graph hardkey again.
Step Three - Creating a Squarewave With DC Offset Voltage, High Z Load Resistance
1) Create a squarewave compatible with TTL or 5 V CMOS logic by pressing the Square
hardkey.
2) Press the Ampl softkey, which will turn it into HiLevel mode. Now use the Numerical
Keypad to enter: 5.00, then press the V softkey. You now have a 5 Vpp squarewave, which
goes between -2.5 V and + 2.5V. Verify this with the MSO.
3) Press the LoLevel softkey, and the
display will say -100 mV. Change this
with the Knob to be 000.0 mV. Your 5
Vpp squarewave, now goes between
0.0 V and + 5.0V. Verify this with the
MSO.
