I am new to IVI drivers and am trying to control an Agilent 54624A with IviScope. I am able to initialize and configure channels/ timebase functions etc. but am having problems with initiating an aquisition and taking measurements. I have tried two methods: (1) running IviScope Initiate Aquisition and then IviScope Fetch Waveform and (2) IviScope Read Waveform. Both methods timeout and do not receive any data. Also, the scope is not taking a single aquistion like I would expect. It stays in run mode. 
This is the software I have installed: 
LabVIEW 8.0 
IVI Compliance Package 2.3 
ag5462x driver from NI site 
Any ideas?
