Model 4200-SCS User’s Manual Section 1: Getting Started
The arb_array function is used to define a full arb waveform. This function includes parameters
to specify the number of waveform points (length), the time interval (TimePerPt), an array of
voltage levels (levelArr), and a file name (fname). For more information, refer to the Reference
Manual, arb_array, page 8-156.
The arb_file function is used to load the defined full arb waveform into the pulse generator. For
more information, refer to the Reference Manual, arb_file, page 8-157.

Full arb waveform example
KPulse full arb waveforms
The Keithley Pulse tool (KPulse) is a virtual front panel software application used to control the
optional pulse generator cards. KPulse can be used to create, save and output full arb waveforms,
and provides a collection of basic full arb waveform types such as sine, square, triangle, noise,
Gaussian, and calculation. After configuring one of the basic waveform types, you can save it as a
.kaf file. For more information, refer to the How to Generate Basic Pulses in Section 5.
Once a full arb waveform is saved as a .kaf file, it can later be imported back into KPulse. The
waveform can also be loaded into the pulse generator card using the arb_file function. For
more information, refer to the Reference Manual, arb_file, page 8-157.
Pulse card settings
Settings and features for the pulse card are summarized in Section 11 of the reference manual
(see Tab le 11 - 1 in the reference manual). For more details, see How to Generate Basic Pulses in
Section 5. In addition to short descriptions and default settings, the table includes the following:
• LPT function: The Keithley Instruments Linear Parametric Test Library (LPTLib) function
used for each setting or feature. Refer to the Reference Manual, LPT Library Function
Reference, page 8-90 for details.
• Access level: The access level for each setting. If a setting can be independently set for
each pulse generator channel, its access level is “channel.” Otherwise, the access level is
“card” to indicate that both channels are affected.
• Pulse mode: A checkmark (√ ) is used to indicate which pulse mode is associated to the
setting or feature. The “n/a” notation indicates that the pulse mode is not applicable to that
setting or feature.
