Safety Requirement

General Safety Summary

Please review the following safety precautions carefully before putting the instrument into operation so as to avoid any personal injury or damage to the instrument and any product connected to it. To prevent potential hazards, please use the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized for use within the local country should be used.
Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock, it is essential to connect the earth terminal of the power cord to the Protective Earth terminal before connecting any inputs or outputs.
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.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the instrument and check your manual for more information about ratings before connecting the instrument.
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 the danger of electrical shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything Into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.
Use Proper Fuse.
Please use the specified fuses.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.
II DSG3000 User’s Guide
RIGOL
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by RIGOL authorized personnel before further operations. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause an increase of instrument temperature which would cause damage to the device. So please keep the instrument well ventilated and inspect the intake and fan regularly.
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 injuries, it is important to operate the device away from an explosive atmosphere.
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.
Electrostatic Prevention.
Operate the instrument in an electrostatic discharge protective environment to avoid damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making connection.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact with fire. Keep it out of the reach of children. Improper change of battery (note: lithium battery) may cause explosion. Use RIGOL specified battery only.
Do Not Overload the Output.
In order to avoid damage to the instrument, the reverse DC voltage on the RF output connector cannot exceed 50 V; the reverse power must be less than +40 dBm (10 W) in the frequency range from 1 MHz to 6 GHz.
Handling Safety.
Please handle with care during transportation to avoid damage to buttons, knob interfaces and other parts on the panels.

Modulation

Amplitude Modulation (AM)

During amplitude modulation (AM), the modulating signal changes the amplitude of the RF carrier waveform linearly.
To Enable AM
Press AMSwitch to select “On” or “Off”.
On: enable the AM function. The backlight of AM goes on and the AM label is
displayed in the function status area in the user interface.
Off: disable the AM function and this is the default state.
NOTE: When a sweep type is selected, if the step sweep time is lower than 30 ms
and amplitude modulation is turned on, “You can turn on the AM when sweep time is greater than 30ms” will be displayed in the user interface.
To Select the Modulation Source
Press AM Source to select “Int”, “Ext” or “Int & Ext” modulation source.
1. Internal Source
After selecting “Int”, the internal modulation source is turned on. At this point, the instrument provides the modulating signal and you can set the modulation frequency and modulation waveform of the modulating signal.
2. External Source
After selecting “Ext”, Freq and Waveform are grayed out and disabled. The RF signal generator receives the external modulating signal input from the [EXT MOD INPUT] connector (as shown in the figure below) at the front panel. This modulating signal can be any waveform.
NOTE:
external modulating signal should be less than ±0 . 5V.

To Set the Modulation Depth
The modulation depth indicates the extent of output amplitude variation and is expressed as a percentage. The range of AM modulation depth is from 0% to 100%.
Press AM Depth to set the AM modulation depth.
1. Select “Int” modulation source
AM modulation depth (
) and the amplitude difference (
) between the
carrier and sidebands satisfy the following relation:
When modulation depth is 0%, the instrument outputs a single frequency
carrier signal.
The greater the modulation depth is, the smaller the difference between the
output amplitude and carrier amplitude and the better the symmetry of the output amplitudes of the upper and lower sidebands.
2. Select “Ext” modulation source
To achieve a modulation depth of 100%, the external modulation source
must input a signal (±0.5 V).
If the external modulation source inputs a signal (±0.25 V), the measured
modulation depth is 50%.
3. Select “Int & Ext” modulation source
If modulation depth is set to 50%, the modulation depth of the internal modulation source and that of the external modulation source each is 25% respectively. These parameters meet the relationship: the modulation depth setting = the internal modulation depth + the external modulation depth, and the modulation depth of the internal modulation source equals that of the external modulation source.
To Select the Modulation Waveform
Press AM Source to select “Int” or “Int & Ext” modulation source; press Waveform to select “Sine” or “Square” and the default is “Sine”.

When “Int” is selected, the built-in baseband generator (wavetable) provides the modulating signal. At this point, if the IQ modulation switch is turned on, the baseband output switch is turned on at the same time. The RF signal generator will output the I (In-Phase) components and Q (Quadrature Phase) components of the I/Q modulation baseband signal from the [I OUT] and [Q OUT] connectors (as shown in the figures below) on the rear panel.
2. External Source
When “Ext” is selected, the RF signal generator receives the in-phase baseband signal and quadrature phase modulating signal of the I/Q modulation input from the [I IN] and [Q IN] connectors (as shown in the figures below) on the rear panel.

LF output frequency is half the frequency of internal modulating signal.

LF Output

LF output refers to the output of the low-frequency signal generated by the internal generator of the RF signal source. When analog modulation is enabled, LF outputs the internal modulating signal. If the analog modulation is disabled, LF outputs several common waveforms. You can set the frequency and amplitude of the low-frequency signal.

To Enable the LF Output

Press LF to enable the LF output. The backlight of the key goes on and the LF label is displayed in the status bar and the function status area in the user interface. At this point, the [LF OUTPUT] connector (as shown in the figure below) outputs the LF signal according to the current configuration.
