To Set the Sync Output
The Generator provides Sync signal output of CH1 through the
[Sync Out]
Connector
on the Rear Panel. All the standard output functions (except DC and Noise) have a
corresponding Sync Signal. For some Sync applications, they can be prohibited if users
do not want to use them.
In the default setting, the Sync Signal output is disabled. The output Voltage of
the
[Sync Out]
Connector Level is Low.
In the Inverse Mode, the Waveform that corresponds to the Sync Signal does not
Inverse.
If frequency of the standard output function (except DC and Noise) is higher than
2MHz
,
the
Sync output will automatically turn off.
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 the internal Modulating of 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 Modulated Signal). The Sync Signal is also a Square Waveform
with 50% Duty Cycle.
For FSK, the Sync Signal Reference is the Hop Frequency, and the Sync Signal is a
Square Waveform with 50% Duty Cycle. For the Hop Frequency, at the hopping
point, the Sync Signal is TTL Level High.
For the Burst, when the burst starts, the Sync Signal is Level High. At the specific
point when the Cycle Number ends, the Sync Signal turns Level Low (If the
