Power Component Measurements
PA1011 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.

Act as Driver of Piezoelectric Element
Besides, PA1011 could also be used as the driver of piezoelectric
element (10W driver, with additional impedance transformer).
Particularly the piezoelectric element with higher electrostatic
capacity (up to 1000pF), better step responses are gainable from
the PA1011 because of its tiny output impedance.
Furthermore, PA1011 could also be used as the driver amplifier in
research and development or experiment of other technologies.

Troubleshooting RIGOL
4-1
Chapter 4 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 RIGOL for help.
1. No response to the instrument when click “Send” on
the control panel of software after power-on:
(1) Check if the power is correctly connected;
(2) Check if the contact of USB data line is good;
(3) After above checks, restart the instrument;
(4) If it still cannot work properly, please contact your local
RIGOL Support center.
2. Circuit Protection
The instrument will start Overcurrent protection or
Overtemperature protection once the output current is too high
or the internal temperature of PA1011 is abnormal
(Overtemperature) to avoid damages.
The phenomenon of Circuit Protection is:
Overcurrent: The output relay is cutoff, and the yellow
light is flashing.
Overtemperature: The output relay is cutoff, and the green
light is flashing.
PA1011 must be restarted after the Circuit Protection is
launched.

We kindly suggest you to inspect the load of PA1011 or the
ambient temperature and make sure both of these
specifications are within the prescribed limits when the Circuit

the amplifier are Slew Rate and the Heat Extraction when a signal
with high amplitude is input. Along with the frequency increase of
the input signal, the working current and the power consumption of
the instrument without loads as well as the signal distortion will be
increased that may heat the amplifier and reduce the performance.
Thus, we set limits on the relationships between the frequency and
the amplitude of output signals which have high amplitude.
