53131A, 53132A, 53181A VISA COM and VB6.0 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 signale (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.
To run the program, apply a 1kHz signal to the channel 1 input.
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
include the appropriate libraries in the Project/References menu:
"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
