We have an NI GPIB card connected with HP3852A dat acquisition and control unit. The driver software for HP3852A available from ni web site does not include DLL files nedded by Labview. Do you have an idea how to proceed with Labview programming of HP3852AThanks, we got it. Another remark, the HP3852A driver for Labview does not include the HP4708A (20 channel multiplexer with thermocouple compensation). On the other hand, the Labwindows driver include this driver.
