Agilent/Keysight E8311A

The Agilent/Keysight E8311A is a VXI C-size, 1-slot, register-based pulse and pattern generator delivering precise digital pulse patterns across two single-ended output channels. Operating from 1 mHz to 165 MHz, it generates patterns up to 16 Kbit per channel with transition times as fast as 600 ps typical (ECL) and period ranges from 6.06 ns to 999.5 s. Output amplitude spans 100 mVp-p to 10.0 V into 50 Ω with ± (1% + 50 mV) accuracy and 10 mV resolution. The instrument supports multiple trigger modes—continuous, external triggered, external gated, external width, manual, and internal triggered—enabling synchronization in complex test environments. Jitter performance reaches 0.01% ± 15 ps with PLL enabled. Source impedance is selectable between 50 Ω and 1 kΩ, with load compensation for non-standard loads. SMA (f) 3.5 mm connectors provide direct integration into test systems.
