PulseBlasterESR^TM series is a high-speed, programmable, multichannel pulse generator in the PCI or CompactPCI form factor.  Based on the versatile PulseBlaster^TM processor architecture, these boards 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 (40.0 ns at 200 MHz), adjustable to 1.07 seconds in duration, and up to 10 MHz retriggering frequency.
PulseBlasterESR^TM offers up to 24 independently controlled channels, variable output rates, and powerful program-flow features.  Currently available clock frequencies are up to 200 MHz.
