The Keithley Model 3402-F is a high-performance 165 MHz Dual-Channel Pulse/Pattern Generator featuring fixed transition times of <1.6 ns. Combining precise timing, versatile pattern generation capabilities up to 165 Mbit/s, and a clean, low-jitter output, the 3402-F is designed for high-speed digital characterization, serial data simulation, semiconductor testing, and nanotechnology research. Dual-channel synchronization, full SCPI programmability via GPIB/USB, and independently controlled delay, amplitude, and width configurations make it a flexible powerhouse in advanced test environments.
