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.
