Too many GPIB listeners

[Vinson12138]

Hi,

     When I Measurement & Automation Exploer to scan GPIB-USB-HS, It indicates that there are too many gpib listeners, and what should I do?

    PS:

It is ok when I reseat the GPIB

Based on your "ps", it sounds like your issue is fixed.  Sounds like it was a loose connection on the bus.

Are you still having an issue?  How many devices are you connecting to?

1. Maybe it was a loose connection on the bus, it has appeared two times. There is Only one device(Agilent 66319B)
2. if loose the connection on the bus,the NI-Max should prompt disconnection not too many GPIB listeners?

Not if the GPIB connection was loose.  That could introduce noise making it look like multiple devices were trying to respond.
