Description:

The Digitimer DG2A Train Delay Generator Model: DG2A-I98 is designed for precision timing control in testing and stimulation environments. With a frequency range of 1-12Hz and a delay duration of 1 to 12 seconds, this unit offers exceptional accuracy for generating pulse trains and delayed outputs. The DG2A can be triggered by TTL compatible signals, and it features four operating modes: Train, Gated, Free-run, and Single. Whether used for studying the effective refractory period or generating a precise pulse train, this device provides reliability and flexibility.

Key Features:

• Frequency Range: 1-12Hz with adjustable duration from 1 to 12 seconds.
• Four Operating Modes: Includes Train, Gated, Free-run, and Single for versatile functionality.
• Trigger Input: Can be triggered via a TTL-compatible signal or a push-button, with BNC connectors for ease of use.
• Delay Feature: Adjustable delay from 1 to 12ms, allowing for controlled timing and precise outputs.
• Battery Powered: Powered by a single 9V PP3 battery, providing long working life.
• Output: Delayed pulse and sync pulse output at OUT-1 and OUT-2 via BNC connectors.
• LED Indicators: Includes “TOO FAST” Red LED indicator that flashes if the unit is busy processing a trigger.

Operating Modes:

• Train Mode: Converts TTL trigger or button press into a SYNC pulse train with adjustable repetition rate and duration. Introduces delayed pulses after each SYNC pulse.
• Gated Mode: Outputs pulse train while input is TTL high; pulses are gated on/off with an external TTL signal. Delay pulses can be added after SYNC pulses.
• Free-run Mode: Continuously outputs SYNC pulses with adjustable repetition rate while the unit is on, with delay options after each SYNC pulse.
• Single Mode: Converts a single TTL trigger or button press into a single SYNC pulse, with delayed pulses added after the SYNC pulse.

Input Specifications:

• Connector: BNC socket
• Levels: TTL High (>1.5V), TTL Low (<0.8V)
• Polarity: Active High (GATE/TRAIN), Positive edge (SINGLE); can be configured to Active Low and Negative edge via internal jumper.
• Indicator: "TOO FAST" Red LED to alert the user if the unit is busy.

Duration (Train Mode):

• Total Range: 10 ms - 12 seconds in three overlapping ranges.
• Control: Single-turn control marked 1 - 12 seconds with intermediate panel marks.
• Accuracy: ±1% at the 1s and 12s marks, ±5% at intermediate marks.
• Multiplier Options: x0.01, x0.1, x1, with an internal jumper to enable x10 for a total range of 100 ms - 120 s.

Included:

• Digitimer DG2A Train Delay Generator
• Power Cable
• Pair of BNC Connectors

Condition Details:

This unit has been removed from a working laboratory, thoroughly cleaned, and professionally tested to ensure it meets performance standards. It is guaranteed to be fully operational and is ready for immediate use.

INPUT

• Connector: BNC socket
• Levels: TTL high (>1.5V), TTL low (<0.8V)
• Polarity: Active High (GATE/TRAIN) and Positive edge (SINGLE) or Active Low and Negative edge by Internal Jumper
• Internal Jumper: Enable “Active Low” - allowing for an Input that is Low during its active phase, In Active Low an external contact closure can be used.
• Push-button: Has same function as a valid input signal.
• Indicator: “TOO FAST” Red LED that flashes if a Trigger is received whilst the unit is busy.

DURATION(TRAIN)

• Total range: 10 ms - 12 seconds in three overlapping ranges
• Control: Single turn control marked 1 - 12s with intermediate integer panel marks
• Accuracy: ±1% at '1' and '12' marks, ±5% at intermediate marks
• Multiplier: x0.01 ; x0.1 ; x1
• Internal Jumper: Enable “x10” - giving a 100 ms - 120 s total range
