Product catalog summary
Overview: The BNC Model 725 is a Multi-Trigger Digital Delay Generator designed to streamline experiment control by integrating multiple functions into a single device. It eliminates the need for multiple instruments, reducing setup complexity and improving efficiency.
Key Features:
  • Eight timing channels with programmable logic and 10 ns resolution.
  • Supports various input types including logic signals, switches, and computer commands.
  • Operates independently or via computer control using Labview or Windows software.
  • Unique modes such as Dynamic Delay Triggering and False-Trigger Suppression.
Operating Modes:
  • Delayed-Pulse Mode: Generates a pulse after a specified delay.
  • Dynamically Delayed Pulse Mode: Calculates output pulse delay based on input intervals.
  • Toggled Output Mode: Toggles output with each trigger.
  • Noise-Suppression Mode: Outputs pulse only after input remains high for a set duration.
  • Fixed Mode: Output remains constant regardless of input.
  • Passive Mode: Output mirrors or inverts input.
  • Clock Mode: Generates a repetitive pulse train.
  • Timer (TDC) Mode: Measures and stores delay between inputs.
Hardware and Software:
  • Front and rear panels equipped with input/output connectors and control buttons.
  • RS-232 interface for PC connection, supporting various Windows operating systems.
  • timerPRO software for easy programming and control, with LabView drivers available.
Applications:
  • Fluid dynamics experiments using lasers for high-speed fluid flow analysis.
  • High-speed gas flow studies in combustion-driven shock tubes.
Specifications:

Model 725 Multi-Trigger Digital Delay Generator-2

Researchers and system integrators, needing controls and diagnostics for their experiments and systems, are regularly forced to build from scratch or to piece together several boxes. Many hours are spent learning the idiosyncrasies of each box and how to properly couple boxes to each other. Each box has its own programming protocol. Valuable time is lost to tracking connections, taming noisy signals, adjusting timing on multiple boxes and other aggravating chores. Now one box will eliminate much of this. The Model 725 coordinates, integrates and synchronizes complicated setups, simply, reliably...

INTERNAL TIMING PROCESSORS PROCESSOR MATRIX Independent Timing; each timing processor operates in its own mode. Logic Statements (OR, AND, XOR, Negated, etc) can be used to create combinations of external inputs and external outputs. The Rear Panel input and output jacks are the combinatorial logic inputs to the timing processors. FRONT PANEL POWER BUTTON Multi-Function (Powers Unit, Initiates a Diagnostic, Enable/Disable Indicator for Front Panel Controls) FUNCTION BUTTONS Pairs with a channel CHANNEL LED ALL LED Indicates State (Disabled, Trigger Ready, Triggered) Indicates Status for All Channels...

The Model 725s logic is engineered for fast data throughput (11 ns) and minimal throughput spread (< 1 ns). It would be difficult to match this performance with external cabling and hard-wired logic. > The Model 725 hardware controller can operate in stand-alone mode or via computer control. The computer control system uses its own user-friendly software, timerPRO, or LabView,ҙ both tested and proven in many experiments. timerPRO makes it easy to create sophisticated control schemes from your PC. With the Model 725 linked to your computer, youll quickly program, refine and expand experiments....
