To Avoid Fire or Personal Injure
Use Proper Power Line
Use only the special power line of the instrument which approved by local state.
Connect the Signal Wire Correctly
The potential of the signal wire is equal to the earth, so do not connect the signal
wire to a high voltage. Do not touch the exposed contacts or components.
Look Over All Terminals’ Ratings
To avoid fire or electric shock, please look over all ratings and sign instruction of
the instrument. Before connecting the instrument, please read the manual
carefully to gain more information about the ratings.
Not Operate with Suspected Failures
If you suspect that there is a damage of the instrument, please let a qualified
service personnel check it.

Quick start
This chapter shows you how to operate the front/rear panel and
some preparation works when you first use the instrument.
General Inspection
1. Inspect the shipping container.
Keep the damaged shipping container or cushioning material until
the contents of the shipment have been completely checked 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.

Power In
Please plug with DC (12V, 4A) using the power adapter provided in the
accessories.
CAUTION
Do not use any other adapters to supply power for the SPA1010,
or else it may cause degradation or perpetual damage.
Please make sure the vents at both sides and the fan aperture
at the rear panel are visible in operation for normal working.
CAUTION
The input impedance of the instrument Zi is 15 kΩ, and the
range of voltage is -6.5 V ~ +6.5 V or -1.3 V ~ +1.3 V
separately while the voltage gain is set to X1 or X10.
The inputs exceed these ranges may cause damages to the
instrument or other hazards.

Application Examples
Power Component Measurements
SPA1010 could be used as the power amplifier 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.
See the measurement system of a power component below:

Troubleshooting
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.
1. No response to the output when connect the AC power.
˄1˅Check if the power is correctly connected˗
˄2˅Check if the power switch is enable˗
˄3˅After above checks, restart the instrument;
˄4˅If it can’t work properly, please contact SIGLENT for help.
2. Circuit Protection
The instrument will start overcurrent protection or
overtemperature protection once the output current is too high
or the internal temperature of SPA1010 is abnormal
(overtemperature) to avoid damages.

SPA10100 must be restarted after the Circuit Protection is
launched. 

We kindly suggest you to inspect the load of SPA1010 or the
ambient temperature and make sure both of these
specifications are within the prescribed limits when the Circuit
Protection is on.

ǏNote 1ǐ
The output power of SPA1010 is limited by frequency. When input frequency between 500Hz
to 200 KHz, the SPA1010 will deliver 10 watts into a 8Ωload. As SPA10100 has overload
protection circuit and thermal protection circuit to prevent permanent damage, the SPA1010
will not deliver 10 watts any more when frequency is below 500Hz and frequency is beyond
200 KHz.
ǏNote 2ǐ
The Full-power bandwidth refers to the maximum frequency of signal generated with
undistorted and utmost amplitude in AC output state from the Amplifier.

Slew Rate: When you send a large step signal to the amplifier, the output slope of signal will
be stable as a constant at some certain point; this constant is named Slew Rate.
