Absolute
  Sets the limit test to show Fail if one 
of the absolute spectrum emission 
mask measurement results is larger 
than the limit for 
Abs Start and/or Abs 
Stop
Relative
  Sets the limit test to show Fail if one 
of the relative spectrum emission mask 
measurement results is larger than the 
limit for 
Rel Start and/or Rel Stop.
Abs AND Rel  Sets the limit test to show Fail if one 
of the absolute spectrum emission 
mask measurement results is larger 
than the limit for 
Abs Start and Abs 
Stop
 and one of the relative spectrum 
emission mask measurement results is 
larger than the limit for 
Rel Start and 
Rel Stop.
Abs OR Rel  Sets the limit test to show Fail if one 
of the absolute spectrum emission 
mask measurement results is larger 
than the limit for 
Abs Start and Abs 
Stop
 or one of the relative spectrum 
emission mask measurement results is 
larger than the limit for 
Rel Start and 
Rel Stop.
