53131A, 53132A VISA Com and VBNET Rise and Fall Time Example Program
This program shows two different ways to make risetime and falltime measurements
for the 53131A and 53132A Counters. One way triggers the counter at the 5% and 85%
value of the input signal (default values are 10% and 90%). The other way uses the
0.5V low and 4.5V high voltage values of the signal (default values are 0V and 5V).
With the risetime and falltime functions, the counter automatically makes the
channels 1 and 2 a common input configuration. The returned measurements are output
into a list box.
This program uses the Agilent VISACom 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
