Hi All,

I need to run a USB Test application on my infiniium scope, with the Pulse pattern Generator connected to it through GPIB. But when i use the I/O libraries to initiate the communication, for the first IDN query , the pulse pattern generator(81130A) is responding properly. from the user manual of 81130A , once it gets a IDN query it should go into remote mode. but it is not happening that way. when i send IDN query again,, it says no istrument connected. due to this, when i run my USB Test application on my Infiniium which is controlling the pulse pattern generator, it is failing saying that no pulse pattern generator is connected. because of this i cant proceed with my test. please suggest some solution for this....
