Editing the icconfig_<QMO>.ini file
The $KIHOME/IC/icconfig_<QMO>.ini file is a system configuration file that defines the types of
instruments installed in the S530/S540 system, matrix and terminal configuration, and default system
settings. Your Keithley service technician configures this file when your system is installed.
This file can be edited to reflect changes in system hardware or to set different default system
settings.
When editing the icconfig_<QMO>.ini file (where <QMO> is the system QMO number), follow the
guidelines below:
• Make a backup copy of the file before making edits.
• Use only upper case characters.
• Do not use space or tab characters.
• Lines should be terminated with newline characters only (\n).
• Avoid duplicate entries and assignments.
Default system speed
By default, the S530/S540 is configured to FAST mode. S530 systems upgraded from an older
Keithley Test Environment (KTE) version may not have a [SYSTEM SPEED MODE] section in their
icconfig_<QMO>.ini file. This can be added but is not necessary unless you want to change the
settings.
The options for system speed mode are FAST, LEGACY, and CUSTOM. The default is:
[SYSTEM SPEED MODE]
MODE=FAST
When FAST or LEGACY mode is selected, other settings such as SOURCE_SETTLING, NPLC,
ANALOG_FILTER, and DELAY_FACTOR are ignored. If you set the speed mode to CUSTOM, the
system will use the settings specified in the icconfig_<QMO>.ini file.
To set a custom default system speed mode, add the following block to the top of the
icconfig_<QMO>.ini file (example):
[SYSTEM SPEED MODE]
MODE=CUSTOM
SOURCE_SETTLING=3
NPLC=0.01
ANALOG_FILTER=1
DELAY_FACTOR=0
If you have problems with correlation of data using the default FAST mode, your service technician
can add the following line to your icconfig_<QMO>.ini file to force the system to use the older
error mode: TSP_ERROR_MODE OFF (in KTE version 5.6.5 or later).
