Notes:
1.
Reference output tilt is specified as “LINEAR” tilt (as opposed to “cable” tilt).
2. Forward gain and noise figure measured with 0 dB input EQ and 1 dB input pad.
3. Down tilt, the effect of cable, is represented by a (-). Up tilt, the effect of equalization, is represented by a (+).
4. 73 CW NTSC channels loaded from 115 to 550 MHz. Digital refers to 550-1002 MHz loading with QAM
carriers at -6 dB levels relative to analog video carrier levels.
5. X-mod (@ 15.75 kHz) specified using 100 percent synchronous modulation and frequency selective
measurement device.
6. Reverse gain and noise figure for station with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB
output pad.
7. Reverse operational gain, noise figure, and return loss are specified without reverse switch option. If switch is
installed, reduce gain by 0.5 dB, increase noise figure by 0.5 dB, and decrease return loss by 1 dB.
8. Composite intermodulation noise is a broadband noise-like distortion product associated with QAM loading.
9. Distortion performance at reference output levels and tilt. Consult Cisco Systems Engineering for CIN
calculation.
10. The gain at 102 MHz is < 1.5 dB below the gain at 105 MHz. 102 to 105 MHz is recommended for out of band
communication only. No video carriers should be used between 102 and 105 MHz.
