Program Examples
Explained here are basic program examples operating the 6243/44 from a computer through the GPIB bus.
Computer:
Fujitsu FMV-6266T6, Windows 95
GPIB hardware:
AT-GPIB/TNT(PnP) manufactured by NATIONAL INSTRUMENTS
Used module:
Niglobal.bas, Vbib-32.bas (supplied with AT-GPIB/TNT(PnP)
Applied language:
Visual Basic 5
The following examples are Visual Basic program examples performing the same operations as those
described in Section 2.2, “Basic Operations.”
• Program example 1:
Example of DC measurement introduced in Section 2.2.3
• Program example 2:
Example of pulse measurement introduced in Section 2.2.4
• Program example 3:
Example of sweep measurement introduced in Section 2.2.5
• Program example 4:
Example of diode measurement introduced in Section 2.3.1
• Program example 5:
Example of recalling measurement data from the measurement buffer memory
as fast as possible
