Data is based on stations configured for 2-way operation. AC currents specified are based on measurements made with typical CATV type
ferro-resonant AC power supply (quasi-square wave), and standard GainMaker Line Extender power supply (12/24 V DC, pn 593020).
DC supply has a user configurable 30 V, 40 V, or 50 V AC undervoltage lockout circuit. Default setting is 30 V. 40 V or 50 V AC undervoltage
lockout may be selected by changing the position of the lockout jumper.

Notes:
1.
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 (+).

78 CW NTSC channels loaded from 55 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.

Distortion performance at reference output levels and tilt.
Unless otherwise noted, specifications reflect typical performance and are referenced to 68
°F (20°C). Specifications are based
upon measurements made in accordance with SCTE/ANSI standards (where applicable), using standard frequency assignments.
