1General Safety Summary
This chapter contains information and warnings that must be followed to keep
the instrument operating under the appropriate safety conditions. In addition to
the safety precautions specified in this section, you must also follow
recognized safety procedures.
1.1 Safety Terms and Symbols
When the following symbols or terms appear on the front or rear panel of the
instrument or in this manual, they indicate special care in terms of safety.
This symbol is used where caution is required. Refer to the
accompanying information or documents in order to protect against
personal injury or damage to the instrument.
This symbol warns of a potential risk of shock hazard.
This symbol is used to denote the measurement ground connection.
This symbol is used to denote a safety ground connection.
This symbol is used to represent alternating current, or "AC".
CAUTION
The "CAUTION" symbol indicates a potential hazard. It calls
attention to a procedure, practice or condition which may be
dangerous if not followed. Do not proceed until its conditions are fully
understood and met.
WARNING
The "WARNING" symbol indicates a potential hazard. It calls
attention to a procedure, practice or condition which, if not followed,
could possibly cause bodily injury or death. If aWARNING is
indicated, do not proceed until the safety conditions are fully
understood and met.
1.2 Working Environment
This instrument is intended for indoor use and should be operated in a clean,

SPA1010 Power Amplifier User Manual
4 / 16 WWW.SI GLENT.CO M
dry environment with an ambient temperature range of 0 °C -40 °C.
Note:Direct sunlight, radiators, and other heat sources should be taken into
account when assessing the ambient temperature.
WARNING: Do not operate the instrument in an explosive atmosphere
or wet and damp conditions.
CAUTION: Do not connect the output to a signal source or power
source.
CAUTION: The input impedance of the instrument (Zi) is 15 kΩ, and
the range of voltage is -6.5 V ~ +6.5 V (1X voltage gain) or -1.3 V ~
+1.3 V (10X voltage gain setting).
Input exceeds these ranges may cause damages to the instrument or
other hazards.
1.3 Cooling Requirements
This instrument relies on the forced air cooling with internal fans and
ventilation openings. Care must be taken to avoid restricting the airflow
around the apertures (fan holes). To ensure adequate ventilation, it is required
to leave enough gap around the sides of the instrument.
CAUTION: Do not block the ventilation holes located on both sides of
the instrument.
CAUTION: Do not allow any foreign matter to enter the instrument
through the ventilation holes, etc.

1.4 Use The Proper Power Adapter
Use only the power adapter provided in the accessories. Use only the power
cord specified for this adapter and certified for the country of use.
CAUTION: Do not use any other adapters to supply power for the
instrument, or it may cause degradation or perpetual damage.
1.5 Cleaning
Clean only the exterior of the instrument, using a damp, soft cloth. Do not use
chemicals or abrasive elements. Under no circumstances allow moisture to
penetrate the instrument. To avoid electrical shock, unplug the power cord
from the AC outlet before cleaning.
WARNING: Electrical Shock Hazard!
No operator serviceable parts inside. Do not remove covers.
Refer servicing to qualified personnel
1.6 Abnormal Conditions
Only operate the instrument for the purposes specified by the manufacturer.
Do not operate the instrument if there is any visible sign of damage or has
been subjected to severe transport stresses.
If you suspect the instrument’s protection has been impaired, disconnect the
power cord and secure the instrument against any unintended operation.

Proper use of the instrument depends on careful reading of all instruction and
labels.
WARNING: Any use of the instrument in a manner not specified by the
manufacturer may impair the instrument’s safety protection. This
instrument should not be directly connected to human subjects or used
for patient monitoring.

any SIGLENT Function/Arbitrary Waveform Generators but can also be used
with other manufacturers’ products.
Features
10 W output power
Two gain settings (x1 or x10)
Over current protection and over temperature protection
Compact size, easy to carry and use.

3Quick start
This chapter shows you how to operate the front/rear panel and steps for your
first use of the instrument.
3.1 General Inspection
1. Inspect the shipping container.
Keep the damaged shipping container or cushioning material until the
contents of the shipment have been completelychecked and the instrument
has passed both electrical and mechanical tests.
The consigner or carrier will be responsible for damages to the instrument
resulting from shipment. SIGLENT would not provide free maintenance or
replacement.
2. Inspect the instrument.
If there are instruments found damaged, defective or failure in electrical and
mechanical tests, please contact SIGLENT.
3. Check the accessories.
Please check the accessories according to the packing list. If the
accessories are incomplete or damaged, please contact your SIGLENT
sales representative.

5Application Examples
Power Component Measurements
The SPA1010 can be used to amplify the output signal of a generator to
evaluate the performance of a power component. In virtue of its wide
bandwidth and high speed output, users can evaluate or test the components
through various waves, pulses and arbitrary waves.

6Troubleshooting
This chapter lists some troubles that may occur when you use the power
amplifier and the corresponding solutions. Please follow the appropriate steps
to deal with; if the trouble still exists, please contact SIGLENT for help.
No response at the output when connect the DC power.
（1）Check if the power adapter/plug is correctly connected
（2）Check if the power switch is enabled
（3）After above checks, restart the instrument
（4）If it is still not operating correctly, , please contact SIGLENT for help
Circuit Protection
The instrument will trigger over-current protection or over-temperature
protection once the output current is too high or the internal temperature of
SPA1010 is abnormal (over temperature) to avoid damage.
SPA10100 must be restarted after the protection is activated.
Wesuggest you to inspect the load of the SPA1010 or the ambient
temperature and make sure both of these specifications are within the limits
when the circuit protection is activated.

1
The output power of the SPA1010 is limited by frequency. When the input frequency is between 500
Hz and 200 kHz, the SPA1010 is able to deliver 10 watts into an 8 Ω load. As the SPA10100 has
overload protection circuit and thermal protection circuit to prevent permanent damage, it will not deliver
10 watts when the input frequency is below 500 Hz and above 200 kHz.
2
The full power bandwidth refers to the maximum frequency of the signal generated with undistorted
and utmost amplitude in AC output state from theAmplifier.
