7. Every time you set to a frequency, it is better for you to adjust the
Sec/Div to a proper value thus to display a perfect waveform.
8. The V
pp
measurement of the waveform will decrease as the input
frequency increases. Increasing the input frequency gradually until
the V
pp
measurement gets closest to 2.12v.
9. Disconnect the connection of channel 1.
10. Check channel 2 in the same way as step 1 to 9.
For test at 200mv/div, please perform the same operation as that at
500mv/div, except for the initial amplitude and amplitude at bandwidth
listed below.
