Output Synchronization
The generator provides Sync output through the [Aux In/Out] connector on the rear panel. When the synchronization is
on, the port can output a CMOS signal with the same frequency as basic waveforms (except Noise and DC), arbitrary
waveforms, and modulated waveforms (except external modulation).
Function Description
State O Close the sync output
On Open the sync output
Channel CH1 Set the sync signal of CH1.
CH2 Set the sync signal of CH2.
Accept Save the current settings and return to the Utility menu.
Cancel Give up the current settings and return to the Utility menu.

14.1 Sync Signals of Dierent Waveforms
1. When the frequency of the waveform is less than or equal to 10MHz, the sync signal is a Pulse with 50ns pulse width
and the same frequency as the waveform.
2. When the frequency of the waveform is greater than 10MHz, there is no sync signal output.
3. Noise and DC: there is no sync signal output.
14.1.1 Modulated Waveform
• When internal modulation is selected, the sync signal is a Pulse with 50ns pulse width.
For AM, FM, PM and PWM, the frequency of the sync signal is the modulating frequency.
For ASK, FSK and PSK, the frequency of the sync signal is the key frequency.
• When external modulation is selected, there is no sync signal output, for the [Aux In/Out] connector on the rear panel
is used to input external modulating signal.
14.1.2 Sweep and Burst Waveform
When Sweep or Burst function is turned on, there is no sync signal output and the Sync menu is hidden.
