Data is based on stations configured for 2-way operation. AC currents specified are based on measurements made with typical
CATV type ferroresonant AC power supply (quasi-square wave), and Cisco GainMaker HGBT System Amplifier power supply
(2.5 A, 24 VDC, pn 4026517).
CATV type ferroresonant AC power supply (quasi-square wave), and Cisco GainMaker HGBT System Amplifier power supply
(2.5 A, 24 VDC, pn 4026517).
DC supply has a user configurable 30 V, 40 V, or 50 VAC under voltage lockout circuit. Default setting is 30 V. 40 V or 50 VAC
under voltage lockout may be selected by changing the position of the lockout jumper.

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% 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.
Distortion performance at reference output levels and tilt. Consult Cisco Systems Engineering for CIN calculation.
9. 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.
