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 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.

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 cable equalization, is represented by a (+).  Forward internal tilt 
specified is primarily due to an on board equalizer and either a factory configured 9 dB (Manual and AGC stations) or 7.5 dB (Thermal 
station) plug-in interstage equalizer. 

4. 

Loaded with 64 PAL B/G CW carriers from 112-600 MHz. Digital refers to 600-1002 MHz loading with 45 QAM carriers at -6 dB relative to 
analog CW 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. 

Measured and specified as Composite Beat.  

9. 

Tested per CENELEC Standard EN50083-3.  RF output level at 1002 MHz is specified. 

10.  Loaded with 64 PAL I CW carriers from 88-600 MHz.  Digital refers to 600-1002 MHz loading with 45 QAM carriers at -6 dB relative to 

analog CW carrier levels. 

11.  Loaded with 78 NTSC CW carriers from 77-550 MHz.  Digital refers to 550-1002 MHz loading with 53 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.
