Remote Command :DISPlay:RHO:CDOMain:SPAN:STOP <integer>
:DISPlay:RHO:CDOMain:SPAN:STOP?
Example DISP:RHO:CDOM:SPAN:STOP 200

Notes Default value is Device sensitive as follows:
BTS: 511
MS: 255
Couplings The Start Code Number and Stop Code Number are coupled to each other, according to the following
conditions:
(A) Stop Code Number > Start Code Number
and
(B) Stop Code Number – Start Code Number >= 63
If the Changing Start Code Number does not satisfy conditions (A) and (B), the Stop Code Number is
changed to satisfy conditions (A) and (C) below.
(C) Stop Code Number – Start Code Number = 63;
Preset 511
State Saved Saved in instrument state.

Expand
Toggles the expanding function of the code domain power graph between On and Off. When set to On, the
CDP graph is expanded horizontally to show 64 spread codes centered at (max scale)/2 of the marker
position. When toggled back to Off, the spread code range returns to the previous setting.
