Model 588 | 0.001 Hz to 10 MHz 1U Rackmount Digital Delay / Pulse Generator
Available until 2026 – Please see Model 588B or contact us for details
The Model 588 delivers innovative, high-quality timing and synchronization in a compact, low-profile rack-mount design—ideal for remote applications, large-system gating, and system integrators seeking a clean alternative to multi-box/cable setups.
- 8 independent precision timing channels
- Accepts low-amplitude clock input: 20 mV to 100 MHz
- Ultra-low jitter: <50 ps (phase-locked to laser photodiode or external reference)
- Enables direct synchronization with laser systems
- TCP/IP communication with SCPI command support
- Complimentary NI-certified LabVIEW drivers
- Low-profile packaging optimized for rack integration and remote use
Perfect for precision synchronization, laser timing, large-scale test setups, and distributed timing networks requiring minimal jitter and clean system architecture.

Channel Modes Applications
Independent Channel Enable/Disable Delayed Channel Enable – allows flashlamp/diodes to be fired, stabilizing the laser before the Qswitch or shutter is enabled. Single shot or Burst mode laser pulse bursts, controlling either just to Qswitch or entire laser. Duty Cycle mode allows firing laser at an optimal rate, but picking pulses out at the user required rate. Output Multiplexer allows any combination of channels to be output on any of the output ports, providing very complex pulse trains.Specifications
