Power LED is not lit
This means there is no power to the board. Check your power connections. For details, please consult the power supply requirements. After turning power on, the power LED on the front panel of the module enclosure should change from red to orange.
No Waveform Output after starting AWG_WIN application
First download a waveform to the module by choosing a pre-stored waveform in the Waveform panel and pressing the Download
button (at the lower right corner of the waveform panel) to download the parameterized waveform data to the module memory to allow the firmware
to generate the actual waveforms. Remember to wait for the waveform to finish downloading.
Now press the Restart button.
Waveform or spectrum has extra repeated data
If the waveform or its spectrum appears to be correct but has parts of the data repeated, perhaps the Data Length does not match the actual number of data points in your waveform. See the Data Length page for a description of how that parameter can affect the waveform.
Waveform or spectrum has some errors
If the waveform or its spectrum appears to be nearly correct but has errors, make sure the clock frequency of your clock source matches that specified in the computer application. Then, adjust the VREF, DATAN, ATE, and DLL settings in the Signature panel. and or the SEL setting in the Module Parameter panel.
If this doesn't fix all the errors, perhaps data was lost under an inferior signature setting, and you may need to reload the waveform data.
Also, you may try setting your clock source to 1 GHz frequency and 3dBm power and repeating the above steps, in case your clock source settings were beyond the range of the board capabilities.
Try to abort and restart the waveform by pressing the Abort button near the bottom of the Module Parameter page and then pressing the Restart button.
If the problem persists, troubleshoot further by setting the waveform to a ramp, downloading it, restarting, and adjusting the signature settings. If any memory bits are consistently bad, they will be apparent in this linear function.
Waveform did not update after I changed parameters
Press the Download button (at the lower right corner of the waveform panel) to download the parameterized waveform data to the AWG memory to allow the firmware to generate the actual waveforms. You must press this button each time you finish changing the parameters. Remember to wait for the waveform to finish downloading before you press the Restart button.
Current changes when clock frequency changes
This is perfectly normal. The memory requires more power at higher clock frequencies and for various waveforms.
Current changes a few seconds after startup
This is perfectly normal, and you may not even notice it. The current will also increase significantly with clock frequency.
The hardware setup page lists the typical operational voltage and current.
Module ignores trigger and continues to output waveform
You may have pressed the Arm & Ready button twice while the module was waiting for the trigger. This causes the module to generate a hardware trigger. The waveform output becomes endless because the processor is fully occupied and ignores the loop count or trigger requirements.
Simply press the Abort button and then Arm the board again (only once).
Waveform appears shaky
Shorten the SYNCO width, which is the second box after SYNCO on the Module Parameter panel. Try setting it to 0. Or, try using a waveform with a longer data length. If SYNCO is too wide, or if the data is too short, the module may not have enough time to get the waveform data (for the next loop) ready at the next trigger, resulting in a possible delay.
The Module Status does not change
You must press the Update Status
button to see the current status of the module. The status monitor does not
automatically update.
Waveform is truncated
When your waveform data length exceeds the total memory depth, the data will be truncated.
Waveform amplitude is truncated in multi-tone (n-tone) waveform
When the amplitudes are too high the multi-tone waveform (Waveform code 4), the instantaneous amplitude of the envelope waveform may at times exceed the full scale amplitude. If this occurs, the overflow data will be truncated and may appear to have wrapped around to a different amplitude.
Decrease the amplitudes in the second column of the table in which you specified the N Tones. Please see the Waveforms page for an example.
There are fewer than 15 user pages available.
One or more of your waveforms is using up more than one uPage memory partition. You can purge the memory, and then use shorter data lengths, and re-download the data to each page. Please see paging for details on dynamic paging.
The inverse sinc filter has no effect on my waveform
You are probably using a digital waveform (pulse, ramp, or user-defined). Try to use an analog waveform, like a sine function or multi-tone waveform. Open the filter dialog box from the Options menu bar. Ensure that the filter status is "on." You can also try changing the windowing type. Remember to download the data again.
Windows Device Manager says Cypress Generic USB device -- EEPROM missing
Ensure that there is a jumper at JP3 and that the firmware is installed on the EEPROM if you have changed the firmware. Try turning the power off and on again.
The module firmware needs to be updated
Occasionally we update the firmware to improve the functioning of the board. If these updates are available, they can be downloaded from our website. To install the new firmware, please follow the instructions here.
What if I need to contact you for help?
In the event you need to contact us for help, please provide the software and firmware versions, as well as the model and series number, and, if possible, the .log files. The software versions are available in the About page of the help menu in the AWG application. The model and series numbers are marked on the board itself. This information is also available in the Startup Notes provided with the module. The module software records log files in your program directory. If the program is not running properly, please copy and save these .log files before exiting the program. Our contact information is located on the Contact Us page also found on the menu column on the left.
