Using National Instruments LabView as Oscilloscope via Serial Cable

Click For Summary
National Instruments LabView cannot function as a true oscilloscope through a serial cable. While it is possible to connect LabView to an external Digital-to-Analog Converter (DAC) via the serial or parallel port for data acquisition, this method is significantly slower and unsuitable for high-speed measurements typical of oscilloscopes. The serial port is primarily effective for logging slowly varying data, such as temperature. For accurate and efficient oscilloscope functionality, purchasing a dedicated oscilloscope is recommended, as it is both easier and more cost-effective.

Hi everybody,

I have a very simple question for programmers and automation professionals,

My friend told me that I can use the program National Instruments LabView as an Oscilloscope through the serial cable!

Is this true? and what are the limits of this advantage?

I'm using this program for the first time, so can anyone offer me some samples?

Thanks :cool:

No, it is not true.
You can of course use the serial port (or better, the parallel port) to connect to an external DAC and then use Labview to acquire data, but this is slow process and you can never reach the kind of speed you need for an oscilloscope.
The serial port is only useful for logging slowly varying data (e.g. temperature).
 
It will be sooooooo much easier to just buy an oscilloscope if you need a oscilloscope.
 
Not to mention cheaper...
 
I am having a hell of a time finding a good all-in-one inkjet printer. I must have gone through 5 Canon, 2 HP, one Brother, one Epson and two 4 X 6 photo printers in the last 7 yrs. all have all sort of problems. I don't even know where to start anymore. my price range is $180-$400, not exactly the cheapest ones. Mainly it's for my wife which is not exactly good in tech. most of the problem is the printers kept changing the way it operate. Must be from auto update. I cannot turn off the...
