Re: how to save data on a graph and then add new data to it

hey thank alot man, im gonna try to do it with the charts instead.it doesnt matter if its graphs or charts i just want to be able to save the data and add a new plot to it

how to save data on a graph and then add new data to it

i am currently plotting data on a graph from a physical system. However when i want to add new data to the plot, the old one is replaced. I am trying to do more than one plot on the same graph, where the incoming data is at different times. I want something like Excel where i can just add a new plo

Re: setting up differential and single ended connections, multichannel scanning also

i understand what your telling me. thanks alot marcus. All the signals sources that i am inputting to the board are grounded. There is no floating signals.I know how to set up the differential channel.What i want to know is for the single ended input, do i still need to connect AISENSE to GND. If

setting up differential and single ended connections, multichannel scanning also

i am currently using the PCI6014 i have set up the 8 input digital channel, three differential channels and one NRSE channel. I would like to know how to scan from the three differential channels as well as set them up. Also since i am using a NRSE does it mean that i connect AISENSE to AIGND? Chan

i am searching for the image update VIs to download

i would like to refresh my VI that i put up on the web without having to refresh the entire page.From your results i was told to use the image update VIs located somewhere on your website.i have been searching for this for sometime and i cant seem to find it.can you please help me locate it or prov

Is the output from an auto power spectrum complex valued?

i want to display the fourier output of some ascii data that i saved to a text file. however the input to the FFT block must be complex valued.how am i to know what i see is actually the fourier analysis?please help

Re: maximum input frequency of the PCI-6014?

thank alot guys, i think that the support at your company is excellent. You all have saved me alot of time.thanks again vijay

Re: maximum input frequency of the PCI-6014?

Ron that was extemely useful information, however for this application i am using digital inputs and reconstructing the waveform in labview. i guess this would make the problem i am having more clear. can i vary the sampling rate for digital inputs in measurements and explorer?

how can i determine the sampling rate of my board

I am currently using the PCI-6014. I would like to know how fast this board is capable of sampling.can this value be increased or decreased from labview? i am using immediate Digital inputs and my analog signal look fine at low frequncies ( like 1-10 Hz). However when my input siganl increases to 1

Re: How plotting on a digital waveform graph the bit transition in function of the time

My name is vijay. For the scaling on the x axis,can u please tell me what X0 and delta X denotes. What scaling factor are they reffering too? thank in advance. Also in order for you to see the binary representation of your digital inputs u can open up the "read from one digital port" VI located und

Re: How to change the properties of waveform graph from time domain

i have a similiar problem.So what you are saying is that by just changing the scale to decimal after the FFT is taken means that the unit is in frequency?

maximum input frequency of the PCI-6014?

I am using the PCI-6014 configured for digital inputs. At low frequencies my quantized waveform is very smooth however wheni increase my input frequency, teh waveform becomes highly distorted. Im sure its not my A/D converter becomes i am sampling more that eight times the input frequency. Can you

How to write a square wave to an output pin and vary its frequency?

I am using the PCI-6014 and i am interested in generating a square wave as an output using a PFI pin. how can i use a square wave from labview to send it to an output on the PCI6014 board

scaling graph to frequency?

i have succesfully read in data from a digital input and managed to store in a text file. This data appears to be most likely an ASCII format. Are there ASCII to number converters? I would also like to now use this data and perform analysis on them.For example using the FFT etc. I have managed to r

How can i display the signal out of a FFT block to a graph?

What conversion is required in order to convert a the output of a FFT block to a waveform display? The signal input to the FFT block is a binary pattern signal!
