This read-only enumerated object reports the spacing, in MHz, between adjacent RF channels that the terminal is using, a value determined by the ODU's regulatory standard (American or European) and the configured wvLinkCapacity rather than set directly. An RF planner reads this to confirm the terminal's actual channel plan matches the frequency coordination that was approved for that site. For example, confirming wvChannelSpacing shows sevenAndAHalf MHz would validate that the terminal's configured capacity matches what was licensed for that particular channel assignment.
