General Inspection
When you first receive a new DS203 oscilloscope, inspect it by following steps:
1.
Inspect shipping damage. If the packaging carton or protection pad is seriously damaged, keep
the package for returning.
2. Inspect the oscilloscope. Contact us for following problems: (1) surface of device is damaged; (2)
device does not work; and
(3) device doesn’t pass pe
rformance test. If damage is resulted from
shipping, please keep the container and inform the shipping company responsible for shipping this
service.
3. Call RIGOL distributor to arrange for repair/change.
Functional Inspection
1.
Take DSO203 out of the shipping box and remove plastic wrapping. Return the device if there
are signs of damage.
2. Turn on the POWER switch. The homepage of the DSO203 will be displayed.
3. If DSO203 does not turn on, connect it to a computer through supplied USB cable to recharge the
battery, until the red charging LED turns off.
4. Connect one probe to the WAVE_OUT channel, and another probe to the CH_A channel. Make
sure that both probes are set at 1X setting. Turn on DSO203, and it will show the homepage, with
a square wave at 20KHz, Vpp=5V.
5. Check whether the measured values are consistent with standard values. Check CH_B, CH_C
and CH_D.
Firmware Upgrade
Connect the DSO203 to your PC with a mini USB cable. Hold down the Run button while
turning on DSO203. It is now in firmware upgrade mode, and a USB disk should appear on your PC.
Copy the firmware files one at a time. After a file is copied, disconnect DSO203. When DSO203
reconnects, the file you copied will be updated.
The order that you upload the files is very important. Start by uploading the .hex files. Their order is
not important. To upload the .BIN files, you need to first upload the corresponding .ADR file. This
tells DSO203 where to put the binary file. Upload CFG_FPGA.ADR first, and then upload
xxxxFPGA.BIN immediately after. If you make a mistake, delete all the files and start again.
When you're finished uploading all the firmware files, turn off DSO203 to complete the upgrading.
When you boot up DSO203 again, your firmware should be updated. If you get an error message
screen, try uploading the firmware again, carefully following the instructions above.
To upgrade the firmware, please follow these steps:
1.
Open Web to access www.minidso.com , download the latest firmware of your oscilloscope to
your PC.
2.
Hold down the RUN/HOLD switch of DS203 and simultaneously turn on POWER to enter
DFU Firmware Upgrade Mode.
3. Connect DS203 to your PC through the supplied USB cable.
A removable disk named “DFU
V3_10_D” will appear on your PC.
Copy the firmware to the root directory of this disk. Restart
DS203 and the firmware is upgraded.
