Do I have to configure my Oscilloscope in MAX first ?

[obibok]

Hello, I've got a problem with my Tektronix TDS 420A. First I'm trying to find oscilloscope by ipfind("GPIB0") function but it always return 'NON-FATAL RUN-TIME ERROR function ibfind:(iberr==0(0x0)'. I can't do anything. This oscilloscope work fully on the same operating system but in other program written in Delphi. Do I habe to configure my oscilloscope in MAX first if I want to use it in Labwindows 7 ?

please help

ps. I found instrument driver for Tektronix TDS 420 and would like to ask if i can use it to my TDS 420A without any risk ?

Hello Obibok,

The first thing to check would be the interface number for your GPIB card. If you have multiple cards in your system, you might not be addressing the correct board.


You can check if GPIB0 is the correct name for your board by opening Measurement and Automation Explorer (MAX). Under the Devices and Interfaces drop down list, you should see the name of the board you want to access, whether it be GPIB0, GPIB1 etc.
This is the name you should enter into the ibfind() function.


Also note that the ibfind() function should not be used in instrument modules. You should use the "Open Device" panel(OpenDev) instead.


Thanks.

Hi Obibok,

The instrument driver that you have is for the TDS420 & TDS460 family of oscilloscopes, which includes the TDS420A. The driver is also available on this website (Instrument Driver Network).

Follow the instruction offered by Wendy. It is a good idea to scan for the instrument using MAX. That way you have the appropriate GPIB address and you can check if you can communicate with the instrument. It's a good practice that may save you lots of time in the future..

thanks Wendy, thanks Joe.

The problem was in GPIB interface card. I installed the newest drivers for it, and uninstalled NI488.2 drivers!, it seems to be good,now. i will fighting with GPIB and oscilloscope now. I don't have any experience with these, and I will ask for help soon again ..probably : )

what the best i should read ?
