Description The MKBW command displays the wavelength di￿erence between markers #2 and #3, even if the markers are not displayed. MKBW? sends the bandwidth

value to the computer. MKBW ON displays the bandwidth in the message area. MKBW OFF blanks the message.

MKBW can be used as a source of another command. Use MKBW as a source by incorporating the MKBW statement into the source of any spectrum analyzer command having prede￿ned function in its syntax diagram. When used as a source, MKBW uses the wavelength di￿erence for operation by the command that contains MKBW.
