problem with LabVIEW-GPIB tektronix tds 220 oscilloscope

[Young-Mu Jeon(Àü¿µ¹«)]

Hi,

I'm trying to communicate over GPIB with a tektronix tds 220 oscilloscope
using LabVIEW 5.1.
First, I had got the driver (tktds2xx), and had opened the 'tktds2xx.llb'.
Up to this point, I did not meet any error message,
but whenever I run that, I see the following error messages.

Help me solve this problem.!!!!!!!!!

==========================================
Error -1073807265 occurred at VISA Write in
Write in TKTDS2XX
Write.vi->TKTDS2XX
Initialize.vi->TKTDS2XX Getting
Started 2.vi->TKTDS2XX VI Tree.vi.

Possible reasons:

VISA: (Hex 0xBFFF005F) No listeners
condition is detected (both NRFD and
NDAC are deasserted),
============================================

I'm having a similar problem with a TDS210 scope, which I have hooked up to a laptop via a PCM-GPIB card. The card is properly installed, and I've tested the communication and it seems to work. It seems like this should have a trivial solution, but I can't figure it out. Any ideas?

When I don't get the above error message, I get an "insufficient system resources" error from the Initialize VI. The error message I get seems to depend on whether I'm reading the data using the "Read Measurement" VI or the "Read Instrument Data" VI. I'm pretty sure I have all the commands correctly input.
Does anyone know what's going on?

never mind. I found the VISA support page at support/labview/visa/default.htm, with good suggestions for all the visa error messages. oh well.
