Composite Second Order (CSO) The CSO parameter (both sum and difference products) is defined by the NCTA. Composite Triple Beat (CTB) The CTB parameter is defined by the NCTA. Cross Modulation (XMOD) Cross modulation (XMOD) is measured at baseband (selective voltmeter method), referenced to 100% modulation of the carrier being tested.
