HP / Agilent 8112A 50 MHz Pulse Generator

The HP/Agilent 8112A is a fully programmable 50 MHz pulse generator engineered for precision timing, triggering, and waveform synthesis in research, development, and production test environments. It delivers deterministic pulse control across five operating modes

Normal, Trigger, Gate, Ext Width, and Ext Burst - with external modulation capabilities for complex signal generation. The instrument combines fast edge transitions, wide amplitude range, and comprehensive triggering flexibility with an intuitive softkey interface and HP-IB programmability.
