General Safety Summary

Carefully read the following safety precautions to avoid any personal injury or damage to the instrument and any products connected to it. To avoid potential hazards, please use the instrument as specified.

Use Proper AC Power Line

Only the power cord designed for the instrument and authorized by local country should be used.

Ground the Instrument

The instrument is grounded through the protective earth conductor of the power line. To avoid electric shock, please make sure the instrument is grounded correctly before connecting its input or output terminals.

Connect the Probe Correctly.

If a probe is used, do not connect the ground lead to high voltage since it has isobaric electric potential as the ground.

Look Over All Terminals’ Ratings

To avoid fire or electric shock, please look over all ratings and sign instruction of the instrument. Before connecting the instrument, please read the manual carefully to gain more information about the ratings.

Use Proper Overvoltage Protection

Make sure that no overvoltage (such as that caused by a thunderstorm) can reach the product, or else the operator might be exposed to danger of electrical shock.

Electrostatic Prevention

Operate the instrument in an electrostatic discharge protective area environment to avoid damages induced by static discharge. Always ground both the internal and external conductors of the cable to release static before connecting.

Maintain Proper Ventilation

Inadequate ventilation may cause increasing of the instrument’s temperature, which will eventually damage the instrument. So keep well ventilated and inspect the intake and fan

SIGLENT

IV SSG3000X User Manual

regularly.

Avoid Exposed Circuit or Components

Do not touch exposed contacts or components when the power is on.

Do Not Operate Without Covers

Do not operate the instrument with covers or panels removed.

Use Only the Specified Fuse. Keep Product Surfaces Clean and Dry.

To avoid the influence of dust and/or moisture in the air, please keep the surface of the device clean and dry.

Do Not Operate in Wet Conditions.

In order to avoid short circuiting to the interior of the device or electric shock, please do not operate the instrument in a humid environment.

Do Not Operate in an Explosive Atmosphere.

In order to avoid damage to the device or personal injury, it is important to operate the device away from an explosive atmosphere.

3. LAN interface

Used to link the RF signal source to the computer or computer network, the SSG3000X is VXI-11 compliant, supports remote commands based on Socket and Telnet, and uses WEB for remote control. It can quickly build test systems with other standard equipment.

4. USB host

SIGLENT

SSG3000X User Manual 10

The RF signal source can be used as the "main device" to connect to the external USB device. The interface reads the trace or state file from the U disk, or stores the current instrument state or trace to the U disk, and can also save the content displayed on the current screen in .BMP format to the U disk.

5. USB Device interface

The interface can be connected to a compatible computer and controlled by software on the host computer

6. EXT MOD INPUT

Input BNC connection for an external modulation.

7. 10MHz IN

The [10MHz IN] and [10MHz OUT] connectors are commonly used to establishsynchronization between multiple instruments.The RF source can use an internal reference source or an external reference source.

If the instrument detects that there is a valid 10MHz IN signal at the 10MHz In connector, it will used it as an external reference source. At this point the user interface status bar shows "Ext Ref". When an external reference is lost, exceeded, or disconnected, the instrument automatically switches to the internal reference, and the screen status bar will no longer display "Ext Ref".

8. 10MHz OUT

SIGLENT

SSG3000X User Manual 11

If the instrument uses an internal reference source, the [10MHz OUT] connector can output a 10MHz clock signal generated by the instrument and can be used to synchronize other devices.

9. PULSE IN/OUT

The function of the connector is determined by the current mode of pulse modulation.

1) PULSE IN: When the pulse source is "Ext", it is used to input external pulse signals.

2) PULSE OUT: When the Pulse modulation source is "Int" and the pulse output switch is turned on, it is used to output the pulse signal generated by the internal generator. The output signal is related to "Pulse Mode", and can be set to "Single", "Double" or "Train".

10. SIGNAL VALID

When the RF output frequency or amplitude is modified, the RF output connector of the front panel outputs the RF signal at the specified frequency and amplitude after a certain response and processing time in the internal circuit of the instrument. In this process, the [SIGNAL VALID] connector outputs an impulse synchronization signal to indicate the validity of the RF output signal:

 High level (3.3 V): Indicates that the RF signal is being configured;  Low level (0 V): Indicates that the RF signal is stable (effective).

11. TRIG IN/OUT

When PULSE trigger mode is "Int ", the connector can be used to output the trigger signal. When the RF Sweep, LF Sweep, or PULSE trigger mode is "Ext", the connector is used to input the external trigger signal.

12. I INPUT

SIGLENT

SSG3000X User Manual 12

Used to input an external modulated I baseband signal when the external IQ modulation mode is on.

13. Q INPUT

Used to input an external modulated Q baseband signal when the external IQ modulation mode is on. Note: [I INPUT] and [Q INPUT] connectors are only available on models equipped with IQ modulation.

2.1 Frequency Setting

The value of the RF frequency is displayed in the header of the display (―Freq‖). This field

provides the direct input of the RF frequency. Alternatively, you can enter the RF frequency in the ―Freq‖ dialog.

Note that the displayed RF frequency in the header and the RF output frequency, entered in the ―FREQ‖ dialog can be different, as explained in the following section.

If you working with a downstream instrument, e.g. a mixer, you can enter related parameter value in the frequency settings dialog (―Offset‖).

The correlation between the RF frequency, the RF output frequency and the frequency offset is as follows:

―FREQ‖ (in header) = ―RF output frequency‖ (frequency in dialog) + ―Freq offset‖ (offset in

dialog)
