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. For some Sync applications, they can be disabled if users do not want to use them.

Steps for setting the Sync Output:

(1) Press Utility and choose Output Setup, press F2 to select Sync. (2) Press F2 to switch between On/Off. On is to activate the Sync Signal on the Sync

output terminal on the front panel. Off is to deactivate it, 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, PM and PWM, 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 a Sweep which disables the Mark function, the Sync Signal is a Square Waveform

with 50% Duty Cycle. When the Sweep starts, the Sync Signal is TTL Level High and turns Low at the Center of the Sweep. The Sync Frequency equals the specific Sweep time. For a Sweep that enables the Mark Function, the Sync Signal is TTL Level High at the beginning of the Sweep and turns Low at the Mark Frequency.

 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 Waveform has a relative starting phase, it may be not zero intersections). For an infinite burst, the Sync Signal is the same with the Sync Signal of the continuous Signal.

 For the External Gated Burst, the Sync Signal follows the External Gated Signal. But,

8. Troubleshooting

1. The instrument is powered on but no Display.

 Check if the power is connected properly.  Check if the Power Switch is in the proper voltage scale.  Check if the fuse which is below the AC Power socket is used appropriately and

in good condition (the cover can be pried open with a straight screwdriver).

 Restart the instrument after the steps above.  If the problem still exists, please contact Lilliput for our service.

2. The measured value of output signal amplitude disaccords to the displayed value:

Check if the actual load matches the set one. Please refer to "To Set the Output Load" on P31.

3. The Sync output terminal does not output Sync Signal:

Check if the Sync Output switch is activated, and check if the current output signal has a corresponding Sync Signal. Please refer to "To Set the Sync Output" on P32 for more details.

If you encounter other problems, try to reset the settings (refer to "To Return to Default Setting" on P34) or restart the instrument. If it still can not work properly, please contact Lilliput for our service.
