In a multi-site 5G network deployment, SCG-T-EC-S-SCG for T Series supporting external clocking integrates a GPS-disciplined oscillator to deliver sub-nanosecond time alignment across remote radio units. The result is improved network reliability, lower handover latency and full compliance with stringent telecom synchronization standards.
In an advanced R&D lab, SCG-T-EC-S-SCG for T Series receives a low-jitter Rubidium reference via external clocking to drive high-speed ADC/DAC test benches. This ensures accurate jitter and phase-noise measurements, accelerates IEEE-1588 compliance testing and reduces time-to-market for next-generation mixed-signal devices.
In a high-performance data center, SCG-T-EC-S-SCG for T Series synchronized to a PTP Grandmaster over external clocking delivers sub-microsecond alignment across server racks. The outcome is fault-free synchronous storage replication, minimized data corruption risk and maximized throughput for mission-critical applications.

The SCG-T-EC-S (SCG for T Series Supporting External Clocking) is an accessory module designed to enable precise external clock synchronization for National Instruments T Series data acquisition devices.
The SCG-T-EC-S is compatible with all NI T Series multifunction and digital I/O modules that support external clock inputs, including 923x, 920x, and 940x families.
Simply plug the SCG-T-EC-S into the TB-68xx or SCB-68 connector on your T Series device, secure the module with the included captive screws, and attach your external clock source via the front-panel BNC connector.
The SCG-T-EC-S uses a standard 50 Ω front-panel BNC connector; any 50 Ω coaxial cable with BNC terminations is compatible for external clock input.
The SCG-T-EC-S supports external clock frequencies from 1 Hz up to 10 MHz, ensuring precise timing for high-speed and low-speed acquisition.
Yes, you can synchronize multiple T Series modules by daisy-chaining the external clock signal from the SCG-T-EC-S BNC output to each module’s external clock input.
The SCG-T-EC-S supports daisy-chaining across multiple T Series devices in a single chassis; for multiple chassis, use a low-skew distribution amplifier.
In NI MAX, navigate to your T Series device, select Timing Settings, choose External Clock, set the input source to PFI or RTSI, and apply changes to enable SCG-T-EC-S.
The SCG-T-EC-S requires NI-DAQmx 19.0 or later, which provides full support for external clock configuration and synchronization on T Series devices.
Common applications include high-precision waveform generation, synchronized multi-channel acquisition, lab-automation timing, and closed-loop control experiments.
By providing a stable external clock reference up to 10 MHz, the SCG-T-EC-S minimizes timing jitter and phase noise, resulting in more accurate and repeatable measurements.
The SCG-T-EC-S adds less than 10 ns of propagation delay, ensuring negligible impact on synchronization across multiple T Series modules.
Yes, SCG-T-EC-S supports both single-ended and differential clock sources, as long as the input amplitude meets the 0.5–5 V TTL/CMOS threshold specifications.
The SCG-T-EC-S is rated for 0–55 °C operating temperature, 10–90 % non-condensing humidity, and meets CE and FCC Class A EMC standards.
No periodic calibration is required for the SCG-T-EC-S; it ships factory-calibrated with traceability to NI’s ISO 17025 standards.
You can purchase SCG-T-EC-S through NI’s online store or authorized distributors; it includes a one-year NI standard warranty covering defects in materials and workmanship.
