High frequency square wave signal measurement

Square wave pulse signal source calibration


☆ Daily Timing Error of Calibration Device

TD2700 Multi-Function Time Calibrator tunkia

There are the following two ways to calibrate the daily timing error of electrical energy devices.

It can output pulse signals per second with an accuracy of up to 20 ppb (0.02 ppm).

Use the frequency measurement function of the instrument to measure the second pulse signal output by the device.


☆ Device Absolute Clock (Timekeeping)

TD2700 Multi-Function Time Calibrator tunkia

Built-in GPS clock module, real-time clock display, and absolute clock synchronization with EV charger testers and other equipment.

☆ Frequency Meter Calibration

TD2700 Multi-Function Time Calibrator tunkia

TD2700 can output a sine wave reference signal with a fixed frequency of 10 MHz, which can be used to calibrate frequency meters.


☆ Square Wave Pulse Source Calibration

TD2700 Multi-Function Time Calibrator tunkia

TD2700 has a square wave pulse measurement function from 0.5 Hz to 10 MHz, which can be used to calibrate the square wave pulse source.
