Note: Read will return a proper response only when it is called immediately after a Write operation that wrote one of the SCPI query commands. LoadWfm Command Description This command loads a waveform into the connected AWG's internal memory and outputs it from the selected channel. Return value The command always returns Zero as the return value.
Note: The waveform file you are trying to load must be in the current directory. When the load command is sent, the instrument takes some time to load the file especially if they are big files. Since the call is synchronous, the program will not return until the load operation is completed on the instrument. Also note that if the waveform file is corrupt or in the wrong format, the instrument will not load it.
Note: Use this function to transfer an array of data values into an AWG and store it in the form of a waveform file. Be cautious while using this function because if you choose a file name that already exists in the current directory of the Instrument, it will be overwritten without warning. Also note that this is only a transfer command and the transferred file is not loaded into the internal memory of the instrument.
Note: This is a combination of Write and Read commands. The return value always returns the result of the read operation.

File Handling Invalid file or no data points available The file you tried to open is either corrupt or the file does not have enough data points to create a waveform.
The file you opened is of the wrong format. This message appears when you try to close the waveform or application without saving. This error message appears when the file is not supported by ArbExpress or if it is a corrupted file. A maximum of two waveforms can be opened in a Wave Book. You have tried to open or create more than two waveforms in a Wave Book. Only waveforms with files of the same number of points in size can be opened or created in the same window.
Ensure that you are opening a valid file. If you need help to open your file or want to verify your file send the file to techsupport tektronix.
Ensure that the file format is one of the followingwfm,. Select Yes to save the file or No to close without saving. Make sure it is not corrupted file format and it is supported by ArbExpress. If the file is not corrupt and is valid, please contact customer support for more clarification. Open or create the waveform in another Wave Book or a new window. Unexpected file format. You can open only files with " " points in this Wave Book.
Select a waveform with the same number of points as the existing waveform in the Wave Book. Standard Waveform Enter a value This message appears when no value has been entered in a field. This message appears if you have entered an invalid value in the editable fields. The value entered is not within the instrument's range. This message appears when offset crosses the range supported by the instrument. This message appears when the instrument cannot generate the frequency entered because the points per cycles is less than 2 for sine and triangle and less than 10 for square and pulse.
This message appears if the sampling rate exceeds range supported by the instrument. This message appears when the start frequency entered for sweep and multi-tone waveforms is greater than the end frequency. This message appears for sine, triangle, pulse, and square waves when Points per Cycle multiplied by Cycles exceeds the maximum memory limit of the instrument. This message appears if number of points per cycle for the sine and triangle waveforms is less than 2. This message appears if number of points per cycle for the square and pulse waves is less than This message appears when points per cycle is less than 10 for exponential rise, exponential decay, and Sinc waveforms.
Enter a valid value in the field for the instrument selected. For more details refer to the instrument specification. Enter a value with within the range. The value must not cross the selected instruments specification. For more details, refer to the Instrument Specifications. Enter a value that lies within the amplitude range supported by the instrument. Enter a value that lies within the range.
Invalid amplitude. Enter the frequency such that there are at least 2 points per cycle for Sine and Triangle and at least 10 points per cycle for Square and Pulse. Invalid Sampling Rate Range supported by the instrument is xx xx Start frequency greater than end frequency.
Enter a value that lies within the range of the selected instrument. Refer to the instrument specifications for the range supported. Start frequency entered should be less than the end frequency. Enter values for points per cycle and cycle such it does not exceed the maximum memory limit of the instrument. For more details, refer to the instrument specifications.
Increase the number of points per cycle. For sine and triangle waves, the points per cycle should be greater than two to generate a good waveform. For square and pulse waves, the points per cycle should be greater than two to generate a good waveform. Change the cycle or total points such that points per cycle is greater than Can't know what you don't love.
Augustine Can't love what you don't know. Electro Fan Super Contributor Posts: PNG The Ethernet Network Settings menu is displayed. Page 18, Step 3.
The fact that you can successfully ping the machine doesn't answer all the questions. Did you scan the open ports? If not, that should be your next step to see which services are available on the machine. Quote from: tv84 on May 15, , am. Code: [Select]. Quote from: Electro Fan on May 15, , am. Downgraded ArbExpress to v2.
This time 2. Quote from: Zucca on May 15, , pm. The following users thanked this post: Zucca. I guess tv84 suggested that you should scan for open ports on the tek: nmap -p- Thanks tv84, we are on the same page. What worries me, during the ArbExpress 3. NET framework 1. NET framework. Now if I try to install.
NET framework 4. I send an email to Tek support BTW: Is Tek not in this forum yet? Are you sure per Page 18, step 3 that you turned on Ethernet?
