PulseBlasterESR -- the high speed, highperformance, versatile, 24-channel pulse/pattern/word generator operating at clock speeds of up to 250 MHz.

At 250MHz, the PulseBlasterESR is capable of generating pulses/delays/intervals ranging from 20.0 ns to 0.8 s per instruction, with a constant resolution of 4.0 ns. The output lines are impedance matched to 50 ohms.

PulseBlasterESR can accommodate pulse programs with highly flexible control commands of up to 4k program words, featuring loops (nested 8 levels deep), large loop counter (20 bits, up to 1,048,576 repetitions), and deterministic WAIT opcode with a constant latency of 8 clock cycles (32.0 ns at 250MHz), adjustable to 0.8 seconds in duration (up to 15 MHz retriggering frequency).
