PCI-GPIB Programming with Borland C++ Builder 6

[JoseVelasco]

Hello guys, I am developing an application and I need to control a Spectrum Analyzer, I was programming with GPIB a long time ago, and I need to control now from Borland C++ Builder 6.0.

I am using 'Language Interface 32-bits for Borland C++", and I have problems when I try to read data from GPIB.

I do the next:

ibdev(0, 16, 0, T10s, 1, 0)
ibclr(0)
ibwrt(0, "*IND?", 5)
ibrd(0, msg, 2000)

When I do ibrd and I obtain an error in ibsta and I can not read anything, the other commands was okey without errors.

I am following the examples and I am using to compile the "Decl-32.h" and add the library BorlandC_gpib-32.obj to my project.

If I use measseurement application to query the device, the devices respond me correctly, when I try the same commands using "Interactive Control", I obtain the same error that my application.

Anyone knows which is the problem?

thanks!!

Is *IND? a query??

If not, *IDN?   would be better????

I am sorry very much, you have the reason, I was trying to send a wrong command, today I have fix the string and all is right. I get to communicate with Agilent 8720ES perfectly.

Thanks!
