General Inspection

After you get a new Waveform Generator, it is recommended that you should make a
check on the instrument according to the following steps:

1. Check whether there is any damage caused by transportation.

If it is found that the packaging carton or the foamed plastic protection cushion has
suffered serious damage, do not throw it away first till the complete device and its
accessories succeed in the electrical and mechanical property tests.

2. Check the Accessories

The supplied accessories have been already described in the Appendix A: Enclosure
of this Manual. You can check whether there is any loss of accessories with reference
to this description. If it is found that there is any accessory lost or damaged, please
get in touch with the distributor of Lilliput responsible for this service or the Lilliput's
local offices.

3. Check the Complete Instrument

If it is found that there is damage to the appearance of the instrument, or the
instrument can not work normally, or fails in the performance test, please get in
touch with the Lilliput's distributor responsible for this business or the Lilliput's local
offices. If there is damage to the instrument caused by the transportation, please
keep the package. With the transportation department or the Lilliput's distributor
responsible for this business informed about it, a repairing or replacement of the
instrument will be arranged by the Lilliput.

To recall wave file

This function can read the waveform file with suffix of (*.ota) which is cut from SDS series
oscilloscope manufactured by OWON and saved to USB device or cut by the software of
OWON oscilloscope. Then the waveform generator can output the same signal as the cut
wave.

Use SDS Series oscilloscope manufactured by OWON to cut wave:

(1) Connect USB device to SDS series oscilloscope.
(2) Press Save to call out the save menu.
(3) Press the H1 button, the Type menu will display at the left of the screen, turn the M

knob to choose Cut Wave for type.

(4) Move cursor1 and cursor2 to choose the range of wave to be cut.
(5) Press the H2 button, and the input keyboard will pop up. The default name is the

current system date. Turn M knob to choose the keys, and press M knob to input the
chosen keys. Choose and press Enter key of the keyboard to end the input and store
the file with the current name to USB device.

being cut, but when the frequency, amplitude, and offset are set out of the limit range, then the

generator would use the current parameter, which leads to the recalled wave not totally the same

as the cut wave.

2. The max data number of the waveform generator ARB is 8192. When the wave cut from

oscilloscope contains data number more than 8192, the waveform generator will compress data.

On the contrary if the data number is less than 8192, the waveform generator will use linear

interpolation.

To Save and Recall

Press Save function button to enter the file system.

To Use USB Storage

The storage location is divided into the internal storage (FLASH) and the USB device
storage (USBDEVICE). When a USB device is connected, the storage menu will show
"USBDEVICE" and "FLASH". Otherwise, the storage menu will show "FLASH" only.

(1) Install the USB device: insert a USB device into the "⑰USB port" on the front panel

in Figure 4-1, and the screen will show "Detect USB device". Press Save function

button to enter the file system, the storage menu will show "USBDEVICE" and
"FLASH".

(2) Enter the storage: Turn the knob or press / direction key to choose the

desired storage. Press F1 to enter the chosen storage. Provide operations as Next

level, Up one level, New folder, Delete, Rename, Copy, Paste.

(3) Remove the USB device: Remove the USB device from the USB port on the front

panel. The system will inform you "The USB device is removed", and the

"USBDEVICE" in the storage menu will disappear.

6. Communication with PC

The Waveform Generator supports communications with a PC through USB port. You ca n
use the ultrawave communication software to set the parameters, control the output of
the Waveform Generator.
The Waveform Generator supports communications with a PC by SCPI commands
through USB port.
Here is how to connect with PC. Install the ultrawave communication software on the
supplied CD.

(1) Connection: Use a USB data cable to connect the USB (type B) connector on the rear

panel of the Waveform Generator to the USB port of a PC.

(2) Install the driver: When the Waveform Generator is turned on, a dialog will appear

on the PC screen and guide you to install the USB driver. The driver is in the
"USBDRV" folder under the directory where the ultrawave communication software
is installed, such as "C:\Program Files\OWON\ultrawave\USBDRV".

(3) Port setting of the software: Run the ultrawave software; click "Communications" in

the menu bar, choose "Ports-Settings", in the setting dialog, choose "Connect using"
as "USB". After connect successfully, the connection information in the bottom right
corner of the software will turn green.

For the detail communication protocol of SCPI, please refer to AG Series Waveform
Generator SCPI Protocol.

To learn about how to operate the software, press F1 in the software to open the help
document.

Generator SCPI Protocol.

8. Troubleshooting

1. The instrument is powered on but no Display.

 Check if the power is connected properly.
 Check if the Power Switch is in the proper voltage scale.
 Check if the fuse which is below the AC Power socket is used appropriately and

in good condition (the cover can be pried open with a straight screwdriver).

 Restart the instrument after the steps above.
 If the problem still exists, please contact Lilliput for our service.

2. The measured value of output signal amplitude disaccords to the displayed value:

Check if the actual load matches the set one. Please refer to To Set the Output Load
on page 26.

If you encounter other problems, try to reset the settings (refer to To Return to Default
Setting on page 27) or restart the instrument. If it still can not work properly, please
