The Agilent / Keysight 81104A is an 80 MHz single- or dual-channel pulse pattern generator mainframe. Designed to operate with one or two 81105A output modules, it provides versatile pulse, burst, and pattern capabilities, including RZ and NRZ formats up to 16 kbit per channel. With dual modules installed, channels can be added to simulate glitches, test clock-recovery circuits, or generate complex 3- or 4-level codes.
