The slope is defined as the difference between the gain at the start frequency and the gain at the stop frequency. 2. 79 analog channels, NTSC frequency raster: 55.25MHz to 547.25MHz, +37.9dBmV to 46.0dBmV tilted output level, plus 111 digital channels, -6dB offset relative to the equivalent analog carrier. 3. Composite Triple Beat (CTB) - The CTB parameter is defined by ANSI/SCTE 6. Composite Second Order (CSO) - The CSO parameter (both sum and difference products) is defined by ANSI/SCTE 6. Cross Modulation (XMOD) - Cross modulation (XMOD) is defined by ANSI/SCTE 58, measured at baseband (selective voltmeter method), referenced to 100% modulation of the carrier being tested. Carrier to Composite Noise (CCN) - The CCN parameter is defined by ANSI/SCTE 17 (Test procedure for carrier to noise). Data Sheet Rev.
