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
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 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 vol t age since it has isobaric electric
potential as the ground.
Observe All Terminal Ratings.
To avoid fi re 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 rem o v ed.
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 RIGOL authorized pe rson ne l
before furth er operations. Any maintenance, adjustment or replacement especially to circuits or
II DSG800 Performance Verification Guide
RIGOL

accessories must be performed by RIGOL authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause an increase of instrument temperature which would cause
damag e 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 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 fro m 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 dischar ges. Alw ays ground both th e internal an d external condu ctors of cabl es to
release static before making connections.
Proper Use of Battery.
If a battery is suppli ed, it mus t not be ex pos ed 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 ba tte ry only.
Handling Safety.
Please handle with care during transportation to avoid da ma ge to keys, knob interfaces and other
parts on the panels.

12. Each time the output amplitude o f DSG800 is cha nged, modify the configurations of the signal
analyzer accordingly.
a) Set the frequency reference input to external.
b) Set the span to 100 Hz.
c) Set the reference level to -20 dBm.
d) Set the input attenuation to 10 dB.
e) Set the resolution bandwidth to 1 Hz.

[10MHz IN] input terminal of the signal analyzer. Set the signal analyzer to external
reference; set the frequency and amplitude of CH1 of the function/arbitrary waveform
generator to 10 MHz and +5 dBm respectively and turn on the output to synchronize the
function/arbitrary waveform generator and signal analyzer, as shown in Figure 2-8.
Note: The 10 MHz signal output from the function/arbitrary waveform generator must have
relatively higher accuracy (with lower than ±5 ppm deviation); otherwise, this specification
cannot be measured.

2. Connect the [CH2] output terminal of the function/arbitrary waveform generator with the
[10MHz IN] input terminal at the rear panel of D SG800. C onnect the [10MHz OUT] output
terminal of DSG800 with the [RF IN] terminal of the signal analyzer.
3. Set the frequency and amplitude of CH2 of the function/arbitrary waveform generator to 10

Press Peak Search to read the frequency of the signal.
5. Set the amplitude of CH2 of the function/arbitrary waveform generator to gradually decrease
from 0 dBm and mo nitor the signal frequency measured by the signal analyzer; stop the
measurement when the frequency measured is not 10 MHz and record the current amplitude
A1 of CH2 of the function/arbitrary waveform generator.
6. Set the amplitude of CH2 of the function/arbitrary waveform generator to gradually increase
from 0 dBm and monitor the signal frequency measured by the signal analyzer; stop the
measurement when the frequency measured is not 10 MHz (note th at you also need to stop
the measurement if the frequency measured is still 10 MHz when the amplitude of CH2
increases to +15 dBm) and record the current amplitude A2 of CH2 of the function/arbitrary
waveform generator.
7. Record the result of (A1 to A2), namely the 10 MHz reference input amplitude range.
Compare the result with th e specification. If the amplitude range measure d includes the ra nge
