NOTE:
1. Forward gain and noise figure measured with 0 dB input EQ and 1 dB input pad. AGC will provide up to +4.5 and -7.5dB over operating temperature range.
2. Down tilt, the effect of cable, is represented by a (-). Up tilt, the effect of equalization, is represented by a (+).
3. All digital loading. 49dBmV QAM at 1218MHz 18dB linear tilt to 54MHz.
4. QAM above 1026 MHz may be substituted with 192MHz OFDM
5. Distortion performance at reference output levels and tilt. Corrected with source performance backed out.
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.

NOTE:
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 GigaXtend Power Supply (0.82A, 24VDC).
DC supply has a user-configurable 30V, 40V, or 50 VAC under voltage lockout circuit. Default setting is 40 VAC. Under-voltage lockout may be selected by changing the position of the lockout jumper.
