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 t he instrument and any product connecte d to it. To prevent potential hazards, please us e 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 could 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 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 an d markers on the instrume nt 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 t hunderstorm) 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 DSG800 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 oper at io ns. 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 instrument. So please keep the instrument 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 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 i mportant to o perate 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 electrostat ic discharge protective environ ment to a void damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making connections.
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 batte ry only.
Handling Safety.
Please handle with care during transportation to avoid dam age to keys, knob interfaces and other parts on the panels.

To Use DSG800 for the First Time

To Connect the Power Supply

Please connect the RF signal generator to AC power supply using the power cable supplied in the accessories. This RF signal generator can accept 100 V to 240 V, 45 HZ to 440 Hz AC power supplies. The pow er consumption of the instrument cannot exceed 60 W. When the RF signal generator is conne cted to A C power s upply via thi s connector, the instrument selects the correct voltage range automatically and users do not need to select the voltage range manually.
To avoid electric sho ck, use the standard power cable.

Power-on Inspection

After the power supply is correctly connected, press the power key panel to t urn on the RF signal generator. During the start-up, the instrument performs initialization and self-test. After that, the instrument enters the default interface.

When "Int" is selected , the internal modulation sour ce 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
When "Ext" is selected, Freq and Waveform are grayed out and disabled. The RF signal generator receives the external modulating signal input fr om the [EXT MOD IN] connector (as shown in the figure below) at the rear panel. This modulating signal can be any waveform.
Note: The input amplitude of the external modulating signal cannot exceed

The modulation depth denotes the extent of output amplitude variation and is expressed as a percentage. The range of AM modulation de pth is fro m 0% to 1 00%.
Press Depth to set the AM modulation depth.
1. When "Int" modulation source is selected The AM modulation depth (
) and the amplitude difference (
) between
the carrier and sidebands satisfy the following relation.
When the modulation depth is 0%, the instrument outputs a carrier signal
with a single frequency point.
The greater the modulation depth is, the smaller the difference between the
output amplitude and carrier amplitude will be.
2. When "Ext" modulation source is selected 100% modulation depth refers to the modulation depth corresponding to 1
Vpp input amplitude of the external modulation source.
When the input amplitude of the external modulation source is 0.5 Vpp, the
modulation depth actually measured is 50%.

This chapter lists the technical specifications and general specifications of the RF signal generator. The technical specifications are valid when the instrument is within the calibration period, is stored for at least two hours in 0 to 50 temperature and is warmed up for 40 minutes. Unless otherwise noted, the specifications in this manual include the measurement uncertainty.
Typical Value (typ.): the typical performance that 80 percent of the measurement results can meet at room temperature (approxim a tely 25 ). This data is not warranted and does not include the measurement uncertainty.
Nominal Value (nom.): the expected average performance or the designed performance attribute (for example, the 50 Ω connector). This data is not warranted and is measured at room temperature (approximately 25).
Measured Value (meas.): the performance attribute measured during the design phase and used to be compared with the expected performance (for example, the variation of the amplitude drift with time). This data is not warranted and is measured at room temperature (approximately 25).
Note: Unless otherwise noted, all the values in this chapter are the measure men t results of multiple instruments at room temperature.
