KPulse setup and help
The following menus are at the top-left corner of KPulse:
File Use this menu to load/save KPulse setups and exit KPulse. By default, setup files are
saved at the following command path location: C:\S4200\kiuser\KPulse\Setup.
Tools From this menu, click Options to open the KPulse Options dialog box (see Figure 5-2):
• Graphing Options: The following pulse preview graphs can be disabled or enabled:
• Show Pulse Mode Graphs When enabled, shows the Standard Pulse waveform
previewers for each PG2 tab.
• Show Segment Arb Graphs When enabled, shows the Segment ARB pulse
waveform previewers for each PG2 tab.
• Show File Arb Graph When enabled, shows the Custom File Arb pulse
waveform previewer for each PG2 tab.
• Show Arb Generator Graph When enabled, shows the Arb Generator pulse
waveform previewer.
• Trigger Master Select the PG2 that will serve as the trigger master,
or select None if you are not using a trigger master
(see the Reference Manual, Triggering, page 5-3).
Help Use this menu to access Model 4200-SCS Complete Reference information, and to open

Triggering
With a Keithley pulse card selected as the trigger master, its Trigger Out can be used to start
(trigger) itself or other PG2s in the system. For details about using a pulse card as the trigger
master, see the Reference Manual, Pulse output synchronization, page 11-33.
NOTE For the master pulse card, the polarity of the pulse trigger source (pulse_trig_source)
and pulse trigger polarity (pulse_trig_polarity) function must be the same. If you are
using a rising-edge trigger source, the pulse trigger polarity must be positive. If you
are using a falling-edge trigger source, the pulse trigger polarity must be negative.
This requirement applies to all three pulse modes (Standard Pulse, Segment ARB,
and FARB).
NOTE When triggering multiple pulse cards in a master/slave configuration, changing the
master card's trigger output polarity will result in a transition in the trigger output
levels that may be interpreted as a trigger pulse by the other cards.
