3. Use the sampling oscilloscope measurement functions to perform the clock
signal rise and fall time measurement under the clock frequency settings
shown in Table B-8.
4. Change the SMA cable connection from the CLOCK and CLOCK outputs to
CH0 and CH0 outputs, respectively, and repeat step 3 for each of these
channels. Verify that the rise and fall times are within the specified ranges.
5. Change the SMA cable connection from the CH0 and CH0 outputs to CH1
and CH1 outputs, respectively, and repeat step 3 for each of these channels.
Verify that the rise and fall times are within the specified ranges.
