Specify the default system speed mode
Starting with Keithley Test Environment (KTE) software version 5.6, you can specify one of the
following speed modes as the default for your system:
FAST:
Produces faster measurements than previous KTE versions, with little or no effect on data
correlation. This mode is the default setting starting with version 5.6.
LEGACY:
A system speed mode that you can specify if you experience problems with the data you
are getting in the fast mode. This mode has speed and resolution performance similar to those in KTE
versions 5.5.1 or earlier.
CUSTOM:
Allows you to optimize your system by making adjustments to delay, filtering, and
analog-to-digital (AD) conversion settings.
The S530/S540 can be set up to automatically run in any of these modes by changing the value of
the
MODE
parameter in the
[SYSTEM SPEED MODE]
section of the system
$KIHOME/IC/icconfig_<QMO>.ini
file.
You can also set the speed mode for a specific module by adding the
setmode
command
KI_SYSTEM_SPEED_MODE
modifier to your test sequence. For more information about the
setmode
command and available modifiers, see
(on page 3-74).
For information about setting the default system speed mode in the
icconfig_<QMO>.ini
file, see
Editing the icconfig_<QMO>.ini file
(on page 2-11).
Fixed range versus autorange measurements
Use fixed-range measurements whenever possible. Depending on the measurement, this can
significantly increase the speed of the test sequence.
Fix-range trigger instruments
When you are using triggers, you should fix-range the triggering instrument with the value of the
trigger. If you do not do this, the trigger command forces a measurement to be made after each
sweep point, and the measuring instrument autoranges. Autoranging noticeably increases the total
test execution time.
Use combination commands
Do not use individual
force
X
and
meas
X
commands to sweep a set of points. Use the
sweep
X
command, which incurs significantly less overhead.
