How to acquire all four channels from tektronix TDS 714L oscilloscope via GPIB with LabVIEW 7.1?

[ero]

Hello to everyone!

Could someone please help me to solve the problem I have with communication between my PCI GPIB/+ card installed into my computer and oscilloscope Tektronix TDS 714L?

I’m trying to acquire signals from all four channels of the oscilloscope with the VI I have attached bellow but I can’t find how to do it.

I try to change the string in the block diagram of the VI in the first frame of the sequence structure where the channels are listed but unfortunately it wasn’t right solution. I can acquire only one signal of those fourth cannels.

If someone could be so kindly and fix the attached VI for acquiring all four channels of the oscilloscope at time I would be really appreciate.

With kind regards,

Ero

According to the manual, you can specify DATA:SOURCE CH1, CH2, CH3, CH4.

You have to acquire them one after each other !

I am using one Tektronix TDS 714L Oscilloscope having RS 232 and GPIB communication port.

Is there any labVIEW driver for communicating that device.

If it is available means please suggest me.

You really should have started a new thread instead of asking an almost completely unrelated question on an old thread.

I found a driver the Tektronix 7X4 oscilloscopes here: http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9698659CE034080020E748...
