Verifying Oscilloscope Performance

To verify bandwidth

In this test you verify the bandwidth of the oscilloscope by using a constant
amplitude signal generator. The frequency of the signal generator is set to
250 kHz to establish a reference level. Then, the frequency is changed to the
upper bandwidth limit and the level is checked to see if it is 3 dB from the
reference level.
The following procedure is a simple method to check bandwidth. However,
there is a possibility of measurement uncertainty with a constant amplitude
signal generator. If you need a more exact procedure for checking bandwidth
see, "To verify the bandwidth (alternate method)" on page 4–12.
