Notes: Unless otherwise noted, specifications reflect typical performance and are referenced to 20 ºC.
1. Forward internal tilt specified is primarily due to an on-board equalizer 7 dB and a factory configured 7 dB linear output equalizer.
2. Forward Gain and Noise Figure measured with 0 dB input EQ and 0 dB input pad.
3. With 1 dB interstage Pad installed for 1 GHz.
4. Tilt 14 dB.
5. Distortion performance reference output level is 50 dBmV (1 port). Digital refers to 550 MHz to 1 GHz loading with QAM carriers at -6 dB
relative to analog CW carrier levels.
