Monitoring oscilloscope with labview 7.1

[gigi85]

hello all, i'm controlling a Tektronix DPO 4054 via USB,

i have a question for you...in what way can i get my waveform and show it in labview? a would a real time graph in labview

Another question...i would check if my waveform is in a range between -5/+5 volt...in what way can i calculate it? 

thanks to all

A regular graph should be fine and I expect the example in the driver uses one.

One way is to wire the waveform array to the Array Min/Max function and go from there.

i can't have examples 😞 the downgrade returned errors 😞

if you can explain me better it would be nice 🙂

You can post version conversion requests on the Version Conversion board.  Turnaround is usually pretty good.  When you get the driver API converted, the examples should tell you what you need to know.  Let us know if you run into further issues.

KC just converted my drivers...bu for examples was not possible 😞

i'm trying to see my waveform in labview but i cannot find the correct driver, or i dunno in what way i have to do it 😛

Perhaps it would be helpful if you understood what the instrument is doing by reading the manual.

Drivers are not the magic answer if you don't know how to use your oscilloscope.

nyc...i have read programmer manual....my english is not perfect and i find diffucult all little differences between 30-40 commands that speak about transferring waveform...

if i'm searching something usefull in driver is because i don't understand which command(s) i have to use...isn't it?

The current driver database says the oldest version a DPO4034 driver is available for is 8.2.1. We control our MSO4034 using the current drivers in current LV versions. That works very well.

If you have an LV driver in version 7.1 and it doesn't work properly you can always send explicit commands to the instrument. The Tektronix documentation on command syntax is certainly available. I did that many years ago for a TDS210 using the serial and the IEEE488 interfaces in an LV6.n version. It was actually not too difficult.

could you tell me which block do you use to get waveform please? 

my problem is that i can't understand which is the correct command to give to labview to do it 😞

The simple answer is to use the Read (Single Waveform) function to acquire a signal. Of course, you will need to use other functions to setup the scope and trigger an acquisition. Most of the functions should be fairly self expanatory. Use functions to set the horizontal, vertical, etc. in the Configure folder of the downconverted driver.
