HP / Agilent 8005B 20 MHZ, DUAL-OUTPUT PULSE GENERATOR

The HP/Agilent 8005B is a 20 MHz dual-output pulse generator engineered for digital circuit testing, time-domain analysis, and general electronic characterization. It delivers simultaneous positive and negative pulse outputs plus a separate TTL output, all independently controllable. With pulse widths spanning 25 ns to 3 s, transition times as fast as 10 ns, and amplitude control from 300 mV to 10 V, the instrument accommodates both precision pulse generation and rapid signal switching across a wide operational bandwidth.
