1 Connect the equipment (see Figure 10 ).
a Connect the signal generator output to the oscilloscope channel 1
input.
2 Verify the trigger sensitivity when the vertical scale is
≥
5 mV/div.
For each of the bandwidth boundaries (maximum bandwidth and
10 MHz):
a
Press the
[Default Setup]
key.
b
Set the output frequency of the signal generator to the bandwidth
boundary and set the amplitude to about 10 mVpp.
c Press the [Auto-Scale] key.
d Set the horizontal scale so that a few cycles of the waveform are
displayed.
e
Set the input channel’s probe attenuation to 1X.
f Set the input channel’s vertical scale to 5 mV/div.
g Decrease the amplitude from the signal generator to the specified
vertical division (1.5 div at maximum bandwith or 1 div at 10 MHz).
