To verify bandwidth (alternate method)
In this test you verify the bandwidth of the oscilloscope by using a power
meter and power sensor to set the output of a signal generator at 1 MHz and
the upper bandwidth limit. You use the peak-to-peak voltage at 1 MHz and
the upper bandwidth limit to calculate the bandwidth response of the
oscilloscope.
