ramp to oscilloscope

[hood1]

hello everybody

when i send a sine that is periodic signal  to oscilloscope.it displays the signal on oscilloscope. but when i send a ramp to oscilloscope. it does not display a ramp on the oscillocope. why? i am using the same analog output functions like AO write and AO start to send the ramp to oscilloscope. the board i am using is AT-MIO-16XE-50.

i attach the VI.please update me what wrong i am doing?

regards

The ramp you are calculating has a maximum amplitude of 1000, which would generate a 1000 Volt signal. AS the cards maximum votage it can generate is 10 Volts, it will only ramp up to 10 volts, and keep this level until you reset the output.  So you might see a very short ramp (in the first 10 ms) and a continous 10 Volt level for the rest of the 990 ms.

You have to adjust the maximum of the ramp to 10 Volts
