Just a quick note to anyone who might be using LeCroy IVI drivers (at least for the Wave Runner 6100 oScope) with LabVIEW. It appears that if you try to recompile them for LabVIEW 7.1, they won't work. It shows up as an "IVI Error Conversion" VI that won't run (broken arrow). Not only will it not run, but it won't give you any information as to why it isn't running. (the first time I've ever seen this)
LeCroy has been made aware of this problem and is troubleshooting/fixing it. (In the mean time, I bought a Tektronix instead. Needless to say - no problems with it.) John
