1) OIP3 and OIP2 are measured with two tones at an output power of +10 dBm/tone
separated by 6 MHz.
2) OIP2 is measured at F1+F2 Frequency.
3) CSO & CTB was measured at 335.25 MHz. For 116 flat channels at the input, measured
at the output were 77 analog channels (55 MHz to 550 MHz) @ +20 dBmV per channel
and 39 digital channels (550 MHz to 750 MHz) @ 6 dB lower than that of the analog channel.
