The Model 577 Digital Delay / Pulse Generator represents the latest in timing capabilities. With up to 8 outputs configurations as varied as the applications the product serves, the Model 577 is clearly our most versatile instrument. We have combined advanced features such as a Labview/USB interface, complex burst sequences, Divide-by-N, Setting Profiles, Dual Triggers, Dual Gating, Clock Divider, Pulse Picking and Negative Delay with core technology in precision timing. Our 250pS Delay & Width resolution, and 200pS internal jitter, allow users great confidence in setting up an experiment or synchronizing multiple events.

Illuminated Channel Enable Buttons: Each channel has a designated enable/disable button. When individual channels are active or enabled the buttons are illuminated. This allows for easy reference and avoids any confusion of output operability. The run/stop indicator on the front panel LCD display as well as an illuminated run/stop button further simplify setup.
Selectable Clock Reference: The Model 577 offers additional inputs and outputs for external clock syncing. Specify your input / output reference frequency (10MHz to 100MHz). Sync with the Mode Lock Oscillator of a laser, or phase lock multiple units with one clock.
Flexible Gating Options: The Model 577 is packed with gating options for almost any setup. You may gate with a channel or on any input. You may gate individual channels or gate all. Gate immediately (output inhibit) or gate after a pulse (pulse inhibit).
External Trigger Options: Select channels for internal / external triggering, or free-run. Triggered channels have flexible output choices: single pulse, burst at its clock rate, continuous pulse train or a series of on/off pulses (duty cycle).
Individual Rates: Each channel can have individual channel rates (either To or Tx... where Tx is the alternate channel rate for that specific channel... e.g. T1 for Channel 1). This is similar to having a separate clock for each output.
Auto-Save: Forgot to save your settings? The Model 577 stores your setup configurations while powering down. Recall is automatic on powerup.
Dual Input Panel Connectors: The Model 577 offers two inputs for triggering or gating. User may specify electrical or optical input signals, and configure any trigger/gate combination. Use Trigger #2 to disable a triggered pulse train.
Front Panel High Voltage: Our modular architecture allows us to offer expanded functionality on user-selected front panel outputs. We offer a front panel High Voltage option ( adjustable to 35V, 200 mV steps) on 2, 4, 6 or all 8 channels.
Front Panel Optical: Many applications benefit from optical signals. For noisy environments, or communications applications, we offer an LED output stage at the front panel. This modular option can be configured for 2, 4, 6 or 8 outputs at 820nm or 1310nm.
Combined output types: The outputs are configured in modules and output types are combined in pairs. Thus one may select optical, standard electrical or high voltage electrical in pairs for their instrument. For example, a 8 channel unit may have optical, standard electrical and high voltage outputs all on one instrument. Custom or additional output modules will be added as the need arises.
Field Programmability: The instrument can now have functions upgraded in the field, such as a special or custom feature upgrade via a fully programmable FPGA.
