can any one help me who to show a signal on graph or chart from DAQ assistant VI ( attached). i am trying to produce pulses from PXI-6238 on PFI6 . the same singnal i like to view on LabVIEW Front Panel graph and then on Osiciloscop. I also like to control the time period/ frequency from HMI not every time from the DAQ wizard.
thanks in advance
I found some code that is used to generate digital pulse. Please let me know if this can produce a digital pulses up to 10kHz on PXI-6238?
I also like to plot the digital pulse as well on chart or graph. Please help where to connect the waveform inputs to display what LabVIEW is making out of the card?
please find Pics and vi in the attachement.
Thanks in advance.
Please find pics and vi in the attachment. as told earlier that i want to Generate pulses upto 10 Khz ,as per PXI Spec sheel i can go up 10MHz. I want to show on my Front panel the wave produce on chart/graph. But first problem is that i am not getting more than 100Hz frqency . Secondly my PXI-6238 has only two counters. I have to read the same counter on which i am producing pulses(writing):? i am getting some problem please correct my vi if possible.
Thanks in advance.
dennis please do a fovour if you can modify my vi. i am not getting your point. i tired a lot.
i shall be very thankful to you.
at last i got some pulses on osicilloscop with both , through Programming and Test Panel in MAX. I have same pulse shape from program and scope ( attached). i thinks this not the requird one. The frequency varied between ( suppose 1000) from 500 to 1000 , flucating. What could be the reason ? Card problem, Scope problem or some thing elase? It give me only one sample written. Why it should be multiple. Plase also let me know how could i vary frequancy at run time? beascuse i doest accept change ducing run time.
Thanking all of you .
