I. Hardware Wiring and Synchronization Preparation
Use BNC tee adapters to connect the synchronization trigger signal port of the master channel to the external trigger input of each slave channel, establishing a unified synchronization trigger link.
Confirm that all channel terminals are free of loose connections and oxidation to avoid delays or deviations during signal transmission.
II. Master Channel Reference Configuration
Set the master channel's signal source clock to "Internal" as the clock reference source for the entire multi-channel system.
Select a square wave output for the master channel, enable the BURST function, set the type to "Infinite," select "Manual" for the trigger source, and set the trigger output to "Rising Edge."
III. Slave Channel Synchronization Configuration
Set the signal source clock of all slave channels to "External," following the master channel's clock reference.
Select an output waveform that matches the master channel for all slave channels, enable the BURST function, set the type to "Infinite," select "External" for the trigger source, and set the trigger input to "Rising Edge."
IV. Synchronization Triggering and Calibration
Power on the master channel device first, then power on all slave channel devices sequentially, ensuring the clock reference source starts first.
Click the "Manual Trigger" button under the main channel's BURST function to synchronously start outputting signals from all channels.
Use an oscilloscope to acquire the output signals from all channels. Fine-tune the time phase difference of each channel using the delay parameter in the Burst menu until the synchronization deviation of all channel signals is ≤0.01s.
V. Resetting the Synchronization Status
Enter the device's Utility menu and set the power-on startup option to "Last Value." The device will automatically load the configured multi-channel synchronization parameters upon the next power-on, eliminating the need for repeated settings.
This synchronization operation process is perfectly suited for field scenarios involving batch verification of hot runner multi-channel signals. It can quickly achieve high-precision synchronous output of multiple analog signals, significantly improving multi-channel verification efficiency.
