Setting The Number Of Power Line Cycles; Setting A Custom System Speed - Keithley S535 Administrative Manual

Section 4: Maintenance

Setting the number of power line cycles

The default number of power line cycles (NPLCs) for measurements using the S535 can be set in
several ways:
Specify in the icconfig_<QMO>.ini file; your field service engineer (FSE) can change this from
the factory default setting (see
Specify using the setmode KI_INTGPLC modifier (see "setmode" and "setmode modifier tables"
in the Keithley Test Environment (KTE) Programmer's Manual (part number S500-904-01) for
details); this setting does not persist through a power cycle
The system default NPLC setting is 0.01. However, this setting differs for some commands,
source-measure unit (SMU) instruments, and ranges. See
for details.

Setting a custom system speed

The LEGACY speed mode has been deprecated in KTE version 5.8.0. If you select this mode, the
default system speed settings are used.
If you need different system speed settings than those set at the factory, you can ask your field
service engineer (FSE) to specify custom speed settings in the icconfig_<QMO>.ini file. 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 system default NPLC setting is 0.01. However, this setting differs for some commands,
source-measure unit (SMU) instruments, and ranges. See
for details.
