MSO/DPO Tek 4034 USB Communication

I am using Tek MSO/DPO4034 with USB Communciation and Labview 8.2.1 Instrument Driver.

I am getting an error with I talk to scope more than twice. I have 10 separate tests. If I run them individually, I am ok.

If I run them as together in sequence.  I get this failure Status: 0xBFFF0015 (VI_ERROR_TMO) most of the time. I will pass once in a while.

I use the same setup each scope use. I change the meaurement type & timebase value.

> VISA Write ("USB0::0x0699::0x0401::C021220::INSTR", "VERB OFF;")Process ID: 0x00000FB0         Thread ID: 0x00000FDCStart Time: 10:48:24.751       Call Duration 00:00:02.016Status: 0xBFFF0015 (VI_ERROR_TMO)

I tried putting delay time of .2 to .5 sec between scope setup. No success.

Capture file is from NI Spy.

Any help would be appreciated.


Thanks,

Greg
