Section 7 Sample Programs
7-8
Appendix B of the volume “Panel Operations” describes the parameters to be initial-
ized by the above programs.
Use the GPIB address value defined on the Instrument Setup screen of the MT8801C
as the address value on line 6 (see paragraph 3.2).
Lines 9 to 15 are initialization routines of the GPIB interface.
Line 10 initializes the GPIB board on the controller and sets the variable Ans%. No
time-out is set here, but an appropriate time-out value can be set if necessary.
Line 11 initializes the GPIB interface function (it does not initialize any other func-
tion).
Line 12 performs initialization related to GPIB message exchange of the MT8801C.
Line 14 initializes the MT8801C device (initialization related to measurement).
The GPIB commands for device initialization are classified into IP, PRE, INI, and
*RST. Use IP, PRE, and INI as the same function. The initialization range of the
*RST command is wider than that of other initialization commands.
For the initialization range, see Section 5.
Generally, execute INI and *RST as follows:
1) Use INI and *RST to set the device to be controlled (MT8801C) to the
initial state.
2) Use the program command to set the required functions.
By using this method, the device can be prevented from being controlled with unnec-
essary functions set.
