   PulseBlasterESR-PROTM series is a high-speed, programmable, multichannel pulse generator in the PCI or USB form factor.  Based on the versatile PulseBlasterTM processor architecture, the USB rackmount/desktop system and PCI board 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), deterministic WAIT OpCode with a constant latency of 8 clock cycles (16.0 ns at 500 MHz), adjustable to 8.59 seconds in duration, or as long as 104 days (at 500 MHz) using the long delay feature, and up to 15 MHz retriggering frequency.

   PulseBlasterESR-PROTM includes 21 output signals and a short pulse feature allowing for down to 2.0 ns pulse at 500 MHz.
