50 MHz Pulse Generators from B&K Precision.
The BK4033 and BK4034 are high performance programmable pulse generators for testing digital systems and circuits based on TTL, CMOS, or ECL technologies. These instruments generate clean and accurate pulses at up to 6 digits resolution with a repetition rate up to 50 MHz, variable pulse widths from 10 ns to 10 s, and pulse delays from 0 ns to 10 s. Output levels are adjustable from -10 V to +10 V, with pulse amplitudes settable from 0.1 Vpp to 10 Vpp into a 50 ohm load. All parameters, modes, and functions are programmable via the front panel or remote control commands. Additionally, the pulse generators provide selectable complementary pulse and double pulse generation in continuous, triggered, gated, and counted burst modes.
For more information, please see the Overview Video.
The specifications describe the instrument performance after 30 minutes warm-up period into a 50 Ω load. All timing characteristics are measured at 50% of
amplitude with fastest edges.
