Description
Model 50P-2063 is a 50 Ohm solid-state programmable attenuator with attenuation range 0 to 31.75dB by 0.25dB steps. The unit operates bi-directionally. The input port is rated for +18 dBm @ 1MHz and +27dBm 12-3000MHz. It is available with SMA female RF connectors. The attenuator has seven individually controlled attenuation steps: 0.25dB, 0.5dB, 1dB, 2dB, 4dB, 8dB and 16dB.
TTL Control
Each of the attenuation steps has a corresponding TTL control line. See the outline drawing for the control pinout. TTL high will turn on an attenuation step. TTL low will turn off an attenuation step. Use multiple control lines simultaneously to set combinational attenuation values. To activate the 0.75dB setting, the 0.25dB/0.5dB control lines must all be TTL high. To activate the 1.5dB setting, the 0.5dB/1dB control lines must be TTL high. To set the attenuator to the insertion loss state (i.e. 0dB setting), all control lines must be set to TTL low.
