Description

Model 75P-180 is a 75 Ohm relay programmable attenuator with attenuation range 0 to 64.5dB by 0.1dB steps.  It operates DC-1000 MHz and is rated for 0.5 Watts of RF input power.  This step attenuator is available with 75 Ohm BNC, F, N or TNC coaxial RF connectors.  The attenuator has ten individually controlled steps:  0.1dB, 0.2dB, 0.4dB, 0.8dB, 1dB, 2dB, 4dB, 8dB, 16dB and 32dB.

TTL Controlled
Each of the attenuation steps has a corresponding TTL control line.  There are ten TTL control lines for this model.  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 7.1dB setting, the 0.1dB/1dB/2dB/4dB control lines must all be TTL high.  To activate the 48dB setting, the 16dB/32dB 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.
