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 t o t he instrument and any product connecte d to it. To prevent potential haza rds, 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 e ssential t o connect the ea rth terminal of 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 the isobaric electric potential as ground.

Observe All Terminal Ratings.

To avoid fire or shock hazard, observe all ratings an d markers on the instrume nt and check your manual for more information about ratings before connecting.

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 expose to 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.

Do Not Operate With Suspected Failures.

If you suspect damage occurs to the instrument, have it inspected by qualified

II DSG3000 User’s Guide

RIGOL

service personnel before further oper at ions. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.

Keep Well Ventilation.

Inadequate ventilation may cause increasing of temperature or damages to the device. So please keep well ventilated and inspect the intake and fan regularly.

Do Not Operate in Wet Conditions.

In order to av oid short circuiting t o the interi or of the device or electric s hock, please do not operate in a humid environment.

Do Not Operate in an Explosive Atmosphere.

In order to avoid damages to the device or personal injuries, it is important to operat e the dev ice away from an explosive atmosphere.

Keep Product Surfaces Clean and Dry.

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

Electrostatic Prevention.

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

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 inst rument, the reverse DC voltage on the RF o utput connector cannot excee d 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.

Amplitude Modulation (AM)

During amplitude modulation (AM), the modulatin g signal changes the amplitude of the RF carrier waveform linearly.

displayed in the function status area in the user interface.

 Off: disable the AM function and this is the default state.

To Set the Modulation Depth

The modulation depth indicates the extent of output amplitude variation and is expressed as a perce ntage . The ran ge of AM modulation depth is from 0% to 100%.

Press AM  Depth to set the AM modulation dept h.

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 sig nal .

 The greater the modulation depth is, the smaller the difference between the

output amplitude and carrie r amplitude and the bet t er the s ymmetry 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 (-1V to +1V).

 If the external modulation sour ce inp uts a signa l (-500m V t o +5 00m V), th e

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 modulat ion de pth + the external modulation depth, and the modulation depth of the internal modulation source equals that of the external modulation source.

I/Q Modulatio n (Option IQ-DSG3000)

I/Q modulation can improve the spectrum utilization. In IQ modulation, two orthogonal carrier signals (with the same frequency and 90°phase difference, generally expressed with Sin and Cos) are modulated with the I (In-Phase component) and Q (Quadrature Phase component) signals respectively and then they are transmitted together.

To Enable I/Q Modulation

Press I/Q  Switch to select “On” or “Off”.  On: enable the I/Q modulation function. The backlight of I/Q goes on and the

I/Q label is displayed in the function status area in the user interface.

 Off: disable the I/Q modulation function and this is the default state.

To Select the Modulation Source

Press I/Q  Source to select “Int” or “Ext” modulation source.

1. Internal So u r c e

When “Int” is selected, the built-in baseband gene rat or provides the modulating signal. At this point, if the baseband output switch is turned on, the RF signal generator will output the I (In-Phase) components and Q (Quadrature Phase) components of the I/Q modulation from the [I OUT] and [Q OUT] connectors (as show n i n t he figure b el ow) on the rear panel.

2. External Source

When “Ext” is selected, the RF signal generator receives t he in-phase baseban d signal and quadrature phase modulating signal of the I/Q mo dulation input fro m the [I IN] and [Q IN] connectors (as shown in the figure below) on the rear panel. When the baseband output switch is turned on, the instrument can output the I (In-Phase) components and Q (Quadrature Phase) components of the I/Q modulation from the [I OUT] and [Q OUT] connectors 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 i nterface. At this point, the [LF OUTPUT] connector (as shown in the figure below) outputs the LF signal according to the current configuration.

To Set the LF Parameters

Press  LF to set the “Waveform”, “Level” and “Freq” of the LF output signal.

1. When the AM or FM/ΦM function and MOD switch are enabled, and the internal modulation source is selected, Waveform and Freq are grayed out and disabled. At this point, the waveform and frequency of the LF output signal should be set via Waveform and Freq (or Rate) under the AM or

M function and the amplitude of the LF output signal (namely the

FM/ modulating signal) should be set via Level.

2. When all analog modulations which use the internal modulation source are turned on simultaneously and all modulation frequencies and waveforms are consistent, the parameter settings of LF output signal are determined by the last configuration.

3. Turn on the MOD switch; any one of the AM or FM/ΦM function is enabled and “Ext” modulation source is selected; all menus under the LF are grayed out and disabled; you cannot set the frequency and amplitude of the LF output signal. At this point, the actual LF output is consistent with the external modulating signal. When “Int & Ext” modulation source is selected,
