Description

Model 75P-119 is a 75 Ohm relay programmable attenuator with attenuation range 0 to 63dB by 1dB steps.  It operates DC-1000 MHz and is rated for 1 Watt of RF input power.  This step attenuator is available with 75 Ohm BNC or F female coaxial RF connectors.  The attenuator has six individually controlled steps:  1dB, 2dB, 4dB, 8dB, 16dB and 32dB.

TTL Controlled
Each of the attenuation steps has a corresponding TTL control line.  There are six 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 7dB setting, the 1dB/2dB/4dB control lines must all be TTL high.  To activate the 17dB setting, the 1dB/16dB 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.
