Description The MKBWA command displays a signal's bandwidth at a user-speci￿ed amplitude below the signal's peak. Two markers are automatically placed at

the amplitude o￿set you specify, and then the wavelength di￿erence between the markers is calculated and displayed. First, use the command to specify the amplitude to perform the bandwidth measurement. Then, turn MKBWA on to view the bandwidth.
