The Model 6454 Headend Driver Amplifier features a simple,
functional design.

1. Tested per CENELEC Standard EN50083-3
2. Measured distortions at 20 degree C. 42 Channel CENELEC standard
channel raster was used with a rated output level of 107 dBuV.
Measurements were conducted using a spectrum analyzer with a
maximum gain and a flat input frequency response.
3. Measured distortions at 20 degree C. 96 PAL B/G channel raster was
used with a rated output level of 103 dBuV. Measurements were
conducted using a spectrum analyzer with maximum gain and a flat input
frequency response.
