Troubleshooting
1. When I power on the instrument, the instrument stays black and does not
display anything.
a. Check whether the power supply has been connected correctly.
b. Check whether the power key is really pressed.
c. Check whether the fuse is blown. If you need to replace the fuse, use only the
specified fuse that conforms to the product.
d. Restart the instrument after finishing the above inspections.
e. If the problem still persists, please contact RIGOL.
2. The USB storage device cannot be recognized.
a. Check whether the USB storage device can work normally when connected to
other instruments or PC.
b. Make sure that the USB storage device is FAT32 format and flash type. The
instrument doesn't support hardware USB storage device.
c. After restarting the instrument, insert the USB storage device again to check
whether it can work normally.
d. If the USB storage device still cannot work normally, please contact RIGOL.
3. How do you set the amplitude of the waveform in dBm?
a. Select the desired channel.
b. In the channel setting interface, check whether HighZ under OutputSet is set to
"On". If yes, you cannot set the amplitude of the waveform in dBm at this time.
Select "Off" to disable the HighZ, and use the numeric keypad, the arrow keys,
and knob to set it to a proper value.
c. Select the desired waveform, tap the Amplitude menu label, and then input the
desired value by using the numeric keypad. Then select the unit "dBm" from the
pop-up menu.
4. The touch-enabled operation does not work.
a. Check whether you have locked the touch screen. If yes, unlock the touch
screen.
b. Check whether the screen or your finger is stained with oil or sweat. If yes,
please clean the screen or dry your hands.
