The Agilent 86112A is a 12.4 / 20 GHz, dual channel, electrical plug-in module for 86100 Infiniium DCA. It provides two measurement channels with user selectable bandwidths. The 12.4 GHz bandwidth mode provides better noise performance for accurate measurement of small signals. The 20 GHz bandwidth mode provides high fidelity display and measurement of very high speed waveforms. Specifications. Electrical Channel Bandwidth:12.4 and 20 GHz. Transition Time (10% to 90%, calculated from TR = 0.35/BW): 28.2 ps (12.4 GHz); 17.5 ps (20 GHz). RMS Noise Characteristic 0.25 mV (12.4 GHz); 0.5 mV (20 GHz). RMS Noise Maximum 0.5 mv (12.4 GHz); 1 mV (20 GHz). Scale Factor Minimum: 1 mV/division. Scale Factor Maximum: 100 mV/division. DC Accuracy (single marker): ±0.4% of full scale ±2mV ±1.5% of (reading-channel offset), 12.4 GHz; ±0.4% of full scale ±2 mV ±3% of (reading-channel offset), 20 GHz. CW Offset Range (referenced from center of screen): ±500 mV. Input Dynamic Range (relative to channel offset): ±400 mV. Maximum Input Signal: ±2 V (+16 dBm). Nominal Impedance: 50 ohm. Reflections (for 30 ps rise time): 5%. Electrical Input: 3.5 mm (male).
