TTL Control
The attenuator has eight individually controlled steps: 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB, 16dB and 32dB. Each of the attenuation steps has a corresponding TTL control line. Use multiple control lines simultaneously to set combinational attenuation values. To activate the 7.5dB setting, the 0.5dB/1dB/2dB/4dB control lines must all be TTL high.
