Dear Mr. I am programinning in labview and I would like to generate from my DaqPad 6020E sawtooth signal. I have a problem becouse I can generate virtually but not in Analog Output. Please verify my program which is attached to the mail. If you can please write your simple program which generate sawtooth signal in analog Output. I was checked programs (examles) in ni.com but i can generate one. I know that AO works becouse i checked it sending sin (as trigonomethry sig) and there was no problem. Best regards

PS. If You speak Polish we can talk in Polish language.
There is a great example that ships with LabVIEW called Function Generator. You can find this VI by going to Help>>Find Examples and searching under DAQ>>Analog output.
I checked it before and every programs didn't work correctly. They run normally without any errors but there was no signal in AOutput. Why? I generate signals with different settings (Buffer, f, ampl, ...) and there was the same problem. Why?
Have you verified output in the Test Panels of the Measurement & Automation Explorer (MAX)? Simply wire analog output 0 to analog input 0. In the test panels, generate a sine wave on the analog output pin. If you can read in the signal on the Analog Input tab, then the board is operational and something is wrong in the code. Check the code to make sure you are referencing the correct device # and channels. Have a great day!
