To Set the Sync Output
The Generator provides Sync output through the
[Sync/Counter]
Connector on the
Front 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/Counter]
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 put off.
•
For Sine, Square 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 Square Waves, the Sync Signal is a Square Wave with the same Duty Cycle
with the main output Square Wave. 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.
