Hi all,
I'm trying to establish communication between a PC w/ LW5.5/CVI and an
HP4155b Semiconductor Parameter Analyzer. On the Analyzer, I've set the
GPIB address, and in my test program, I use that address to call the hp415xa_init()
function of the instrument driver. In runtime, I get a GPIB iberr = 6 (for
timeout) after the program tries to execute an ibwrt("*idn?"). I do however
see a "screen-refresh" response on the Analyzer before it times out, which
means that something got there and then hung. I've tried to diagnose the
problem using IBIC and entering commands from there and tinkering with the
settings, but with little avail; all ibwrt's timeout. (I'm also new to the
GPIB interface.)
If anyone out there
is familiar with this instrument driver or can offer
a suggestion as to where to troubleshoot, your help would be greatly appreciated.
Thanks,
