query the scope untill acquisition is complete

[zamjir]

Hi everyone

I am trying to run a measurment routine on Agilent infiniium 54810A, but I am facing a this problem the scope it does not wait untill the acquisition is complete, so I am trying to use the actn Begain wait for Query.vi and Actn End wait for Query.vi  but the Documentation from National Instrement it is so poor for that Driver. the step I am trying to build are:

1) Set the number of averages (128)

2) set the scope to single acquisition sequence

3)query the Scope untill the acquisition is complete

4)Once the query is complete perform the desired measurement.

5)After that clear the measurement.

please i need help to finishe this routine

thank you

George

What version of LabVIEW are you using? In the version 7.x driver, there is an example called hp548xxa Application 2 that uses hp548xxa Actn Begin Wait for OP Comp to enable a service request and then a hp548xxa Actn End Wait for OP Comp after the acquire function to wait for this service request before retrieving the waveform. It sounds to me like you want to do about the same thing as this example. The functions you mention are used in the hp548xxa Utility Read Binary Data Bloc function to wait after sending the WAV:DATA? command before doing a read of the data. The service requests are completely different.
