synchronization source in the "Sync type" parameter setting box:
Table 16-1 Sync Type
Type of synchronization
Description
CH1
Carrier of CH1
CH2
Carrier for CH2
MOD-CH1
Modulated waveform of CH1
MOD-CH2
Modulated waves of CH2
The upper limit of synchronization signal output frequency is 10 MHz. When the
frequency of the synchronization source exceeds this value, the synchronization
output will be turned off automatically.
Sync Signals of Different Waveforms：
⚫ Basic Waveform and Arbitrary Waveform (AFG mode)
1) When the frequency of the waveform is less-than or equal-to 10 MHz, the sync signal is a
pulse with 25.6 ns pulse width and the same frequency as the waveform.
2) When the frequency of the waveform is greater than 10 MHz, there is no sync signal output.
3) Noise and DC: There is no sync signal output.
4) PRBS: The frequency of the sync signal is the same as the bit rate of the waveform.
⚫ Modulated Waveform
1) When internal modulation is selected, the sync signal is a Pulse with 25.6 ns 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.
2) 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 the external modulating signal.
⚫ Sweep and Burst Waveform
When Sweep or Burst function is turned on, there is no sync signal output and the Sync menu is
hidden.
16.3.3 Multi-Device Synchronization
Synchronization of the frequency and alignment of the phase can be realized between two or
more SDG7000A devices by utilizing the Multi-Device Sync function.
