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 System Amplifier power
supply (2.2 amp, 24 V DC, pn 734771).
DC supply has a user configurable 30 V, 40 V, or 50 V AC under voltage lockout circuit. Default setting is 30 V. 40 V or 50 V
AC under voltage lockout may be selected by changing the position of the lockout jumper.

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 cable equalization, is represented by a (+). Forward internal tilt
specified is primarily due to an on board equalizer and a factory configured 10.5 dB plug-in interstage equalizer.

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.

Tested per CENELEC Standard EN50083-3, with reference output tilt. RF output level specified is at 1002 MHz (forward).
10. Loaded with 64 PAL I CW carriers from 88-600 MHz. Digital refers to 600-1002 MHz loading with QAM carriers at -6 dB relative to analog
CW carrier levels.
11. Loaded with 78 NTSC CW carriers from 91-550 MHz. Digital refers to 550-1002 MHz loading with QAM carriers at -6 dB relative to
analog CW carrier levels.
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.
