The HP/Agilent 8082A is a 250 MHz dual-output pulse generator delivering independent pulse generation across two isolated channels. Each output supports normal and complementary configurations with switchable polarity, making it suitable for digital circuit testing, signal simulation, and logic-level verification in research and production environments. The instrument provides sub-nanosecond edge control, adjustable DC offset, and selectable ECL or 5 V output levels—all protected against short circuits, open circuits, and external voltage faults up to ±6 V.
