Adjusting the Amplitude
There are two methods for adjusting the amplitude.
Method 1
Press the left and right arrow keys to select a digit on the display, then spin the wheel to
increase/decrease the value.
Method 2
Press the button Enter Number, it has green lettering, then type in your desired value using the green
numbers to the left of the buttons. Then choose the correct arrow key, in our case we’ll choose Vpp for
amplitude peak to peak.
Adjusting the Frequency
The frequency is set in the same manner as the amplitude. The arrow keys offers MHz, kHz and Hz
instead of Vpp, Vrms, and dBm.
Offset
Notice the sine wave has no D.C. element. Press the Offset button and slowly spin the wheel left and
right to change the D.C. offset of the signal. (Make sure the oscilloscope is set to D.C. coupling)
Wave forms
The Agilent 33120 A is capable of outputting many different waves.
Sine
We have already learned how to adjust the amplitude and frequency of a sine wave. A very pretty wave
to be sure, but let’s see what charm the other waves have.
Square
1. Press the square wave button and adjust the amplitude to 5Vpp and set the frequency to 1kHz.
2. Press the Offset button and set it to +2.5 VDC.
3. You now have a 5V clock pulse you can use with your circuits.
4. We can also change the duty cycle of the square wave.
5. Press Shift -> %Duty. Move the wheel to change the duty cycle. You can adjust the duty cycle
from 20% up to 80%.
Triangle/Sawtooth/ Noise
1. Press the triangle wave button and observe on the oscilloscope.
2. Adjust the D.C. Offset to 0.0 VDC.
3. Press the sawtooth wave button and observe on the oscilloscope.
4. Press the Noise button and observe on the oscilloscope.
Arb (Arbitrary) (Sinc, Neg Ramp, Exp_Rise, Exp_Fall, Cardiac)
1. Press the Arb button and observe on the oscilloscope.
