Multi generator synchronization
July 19, 2019
1. Introduction
Multi-channel function generators are useful in many situations. For example, in Radar testing the
generator needs to output several phase coherent signals and for the phase to be independently
adjustable for each signal. In 3-phase power line harmonic distortion testing, a 4 channel generator is
required to simulate the multiple voltages and currents.
1.1 Problem
A standalone multi-channel generator can be very expensive.
1.2 Solution
Siglent provides the Multi-Device Synchronization function in the SDG1000X, SDG2000X, and SDG6000X
generators. This allows synchronization among several units in order to output signals with adjustable
steady phase relationships. Thus saving on cost.
2. Setup of Synchronization
2.1 Wiring
Multi-Device Synchronization will require the use of the Aux In/Out and 10 MHz In/Out rear-panel interfaces
to implement the synchronization. First, all the generators' Aux In/Out BNC connectors need to be
connected together. Next, connect the Master unit's 10 MHz Out to the Slave unit's 10 MHz In.
Please note that the SDG6000X family has separate 10 MHz In/Out outputs, so more than two units can
be synchronized. The wiring interconnection concept is shown in Figure 1.

    In this example we are setting all 4 channels as a 1 kHz, 4 Vpp square wave. CH3, CH4 signals viewed on the SDS5000X oscilloscope are output by the Slave generator, note that the phase is drifting. Open the Display/ Persist function to track it on the scope, as shown in Figure 4. © 2018 SIGLENT TECHNOLOGIES | 3...
