how to speedup receiving signal from Oscilloscope

[R_Rajabniya@yahoo.com]

hello every one. 

i have a TEK Oscilloscope(TDS 2012C) and i wnat to analyse signale in labview  that i receive from Oscilloscope. i do it, but it shows in labview so slow with delay. i want to receive signals like Oscilloscope lcd! 

please help me.

Thks.

You'll never be able to transfer waveforms over your unspecified connection as fast as running just the scope. Transfers take some finite amount of time and when a transfer is taking place, no acquisition can be performed. What sort of delay do you see? What is the connection type?

thank you for answer, delay is about 1 second and i use USB connection.

You have not mentioned how many points you are acquiring and I have no idea how you are calculating the delay.

See http://www.ni.com/white-paper/4819/en/ for some benchmarks and ideas. I would go with a pci/pcie digitizer for best transfer rates.

so i can't do it in software! is there any way?  i really need to do it. can i use another connection or external hardware?

I don't know what you want to do in software? You certainly can't do acquisitions and transfers with no delay. The hardware and bus do not permit it. Different hardware such as the digitizer cards from NI with high transfer rates and low latency should have been considered during the design process.

i've noticed what you mean, thank you so much for your help.
