[1] 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, +46dBmV flat output level, plus 75 digital channels, -6dB offset
relative to the equivalent analog carrier.
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.
carrier to intermodulation noise (CIN) - The CIN parameter is defined by ANSI/SCTE 17 (Test procedure for carrier to noise).
[3] Logic high is defined as power enable voltage >2V
[4] Logic low is defined as power enable voltage <0.4V
