To Set the Clock Source
The waveform generator provides an internal clock source and also accepts external clock
source input from the [ Ref Clk/Counter In ] connector at the rear panel.
Note :
The amplitude of the [ Ref Clk/Counter In ] input signal must be over 1 V.

To Set the Sync Output
The Generator provides Sync output through the Sync output terminal on the Front Panel.
All standard output functions (except DC and Noise) have a corresponding Sync Signal.
Press
Trigger
button to activate or deactivate the Sync Signal on the Sync output
terminal on the front panel. When it is deactivated, the output Voltage of the Sync
output terminal is Level Low.
Note :
When the amplitude is relatively low, disabling Sync Signal can reduce the distortion in
output.
The Instructions of the Sync Signal in certain situations:

In the Inverse Mode, the Waveform that corresponds to the Sync Signal does not
Inverse.

For Sine, Square, Ramp and Pulse Signal, the Sync Signal is a Square Signal with 50%
Duty Cycle. When the output is positive, The Sync Signal is TTL Level High compared
to 0 V Voltage or DC Offset; when the output is negative, The Sync Signal is TTL Level
Low compared to 0 V Voltage or DC Offset.

For Arbitrary Waveform, the Sync Signal is a Square Waveform with 50% Duty Cycle.
At the time when the first output waveform point is generated, the Sync Signal
Voltage is TTL Level High.

For Internal Modulating AM, FM, and PM, the Sync Signal reference is the Modulated
Signal (not the Carrier Signal). The Sync Signal is a Square Waveform with 50% Duty
Cycle. In the first half modulation period, the Sync Signal is TTL Level High. For
External Modulation, the Sync Signal reference is the Carrier Signal (not the
