Data is based on stations configured for two-way operation. AC currents specified are based on measurements
made with typical CATV type ferroresonant AC power supply (quasi-square wave), and Cisco GainMaker High
Output System Amplifier power supply (2.5A, 24 VDC, part number 4022846).
DC supply has a user configurable 30V, 40V, or 50 VAC under voltage lockout circuit. Default setting is 30V, 40V,
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).
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 negative sign(-). Up tilt, the effect of equalization is represented by a plus sign
(+).
4. Mixed loading of 79 analog channels (54
– 554MHz) and SC-QAM’s (554- 1218MHz) with 6dB back-off
5. X-mod (at 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. Contact Cisco Systems Engineering for CIN calculation.
