To Set the Sync Output

The Generator provides Sync output through the [Sync] 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.

z In the default setting, the Sync Signal should be connected to the [Sync]

Connector (activated). When the Sync Signal is prohibited, the output voltage

Level of the [Sync] Connector is Low.

z In the Inverse Mode, the Sync Signal does not Inverse.

z 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 High Level

compared to 0 V Voltage or DC Offset; when the output is negative, The Sync

Signal is TTL Low Level compared to 0 V Voltage or DC Offset.

z 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 High Level.

z For AM, FM and PM in Internal Modulation, 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

High Level. 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.

z 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 High Level.

z For the Burst, when the burst starts, the Sync Signal is High Level. At the specific

point when the Cycle Number ends, the Sync Signal turns Low Level (If the

Waveform has a relative starting phase, it may be not zero intersections). For an

infinite burst, the Sync Signal is the same as the Sync Signal of the continuous

Signal.
