This program makes a 4100 points digitizing measurement and stores the readings in memory.

Date: November 1, 2004
Version: 1.0.0.0
Language: Microsoft® Visual Basic .NET version 7.0
Operating System: Windows® NT® 4.0, 2000 Professional, or XP

This program makes a 4100 points digitizing measurement and stores the readings in memory. The program uses a single trigger to start the measurements. The readings are read from memory and loaded into a list box.

The readings are stored internally as Double Integers allowing the 3458A to store a maximum of 5120 readings (this example only stores 4100).

This program uses the Agilent VISA COM objects to program the instrument. To use the IO object in another Visual Basic project, set the reference to add the appropriate libraries in the Project/References menu and COM tab:
  "VISA COM 1.0 Type Library", corresponds to VISACOM.tlb
  "Agilent VISA COM Resource Manager 1.0", corresponds to AgtRM.DLL
  "VISA COM 488.2 Formatted I/O 1.0", corresponds to the BasicFormattedIO.dll

VISA COM comes with the Agilent I/O Library version M.01.01.04 or above.
