Synchronization Considerations


Synchronize operations with shared start triggers and shared scan clocks.

Trigger Connections

Simultaneously start all devices in the session.

Clock Connections

Synchronize operations on all connected devices in the session.

External Clocks, Shared Clocks, and Shared Start Triggers

Acquire Voltage Data Using a Digital Trigger

Use a falling edge digital trigger to initiate analog data acquisition.

Acquire Digital Data Using an External Clock

Acquire digital data in the foreground using an external scan clock.

Acquire Digital Data Using a Shared Clock

Share the clock with the analog input subsystem on your device with the digital subsystem.

Acquire Digital Data Using a Counter Output Channel as External Clock

Acquire digital data using a counter output channel to generate clock pulses.

Multiple-Device Synchronization Using USB or PXI Devices

Synchronize multiple devices in a session using a shared clock and trigger.

Synchronize DSA Devices

Synchronize Digital Signal Analyzer product family devices for accurate audio frequency measurements.

CompactDAQ Synchronization

Acquire Data and Generate Signals Simultaneously

Acquire and generate data at the same time.

Acquire Digital Data Using an External Clock via Chassis PFI Terminal

Use CompactDAQ chassis PFI terminal with external clock.

Synchronize with PFI on CompactDAQ Chassis Without Terminals

Use the external trigger and clock functionality on a CompactDAQ chassis without PFI terminals.

Multiple-Chassis Synchronization with CompactDAQ Devices

Synchronize multiple CompactDAQ chassis
