 If you are using Labview, it makes some sense to use NI hardware if you can, since if you need tech support, NI can help you with both programming and hardware.  If you are using Labview, it makes some sense to use NI hardware if you can, since if you need tech support, NI can help you with both programming and hardware. 
-Having said that, we know NI can't make everything, so over the years here in Physics, we've used Labview to build systems with hardware from other manufacturers, like Agilent (Hewlett Packard), Tektronix, Keysight(Keithley), LeCroy, Neslab, etc. +Having said that, we know NI can't make everything, so over the years here in Physics, we've used Labview to build systems with hardware from other manufacturers, like Agilent (Hewlett Packard), Tektronix, Keysight(Keithley), LeCroy, Neslab, Measurement Computing, etc. 
  
-While Labview drivers for third party instruments can often be downloaded from the Instrument Driver Network at ni.com, they are posted as-is since NI can't test and guarantee them with hardware they don't make. In my experience, they often need debugging. To be fair, some of these are complex instruments, and testing all the combinations of features and settings would take  a LOT of time, and if they are giving them away for free, you can see why there might be some mistakes. Starting with downloaded drivers is still better than starting from nothing, even if you have to fix a few things.+While Labview drivers for third party instruments can often be downloaded from the Instrument Driver Network at ni.com, they are posted as-is since NI can't test and guarantee them with hardware they don't make.
