Source Pulse menu
This menu allows you to set up a source pulse sweep and generate a source configuration list and a
measure configuration list, simultaneously building the trigger model.
Setting Description
Abort on Limit
Determines if the sweep is stopped immediately if a limit is exceeded; options
are:
• Abort the sweep if the source bias or pulse limit is exceeded: ON
• Complete the sweep if the source limit is exceeded:
OFF
Acquire Readings
Enables or disables measurements at the top of each pulse:
• Enable: On
•
Disable: Off
Bias
Output level the instrument sources before the first pulse and returns to
between pulses (delay and off time):
• Current: -7.35 A to 7.35 A
•
Voltage: -105 V to 105 V
Bias Limit
The current or voltage limit for the defined bias level:
• Current: 10 nA to 7.35 A
•
Voltage: 2 mV to 105 V
Count
Pulse Train sweep type only; the number of pulses in the pulse sweep:
• Finite: 1 to 268435455
•
Infinite: Continuous loop
Delay
The amount of time that the instrument stays at bias level before each pulse
(in seconds): 0 to 10,000 s
Dual
Not available for the Pulse Train sweep type: determines if the sweep runs
from start to stop and then from stop to start:
• Sweep from start to stop only: Off
•
Sweep from start to stop, then stop to start: On
Generate
Creates a trigger model and source and measure configuration lists for the
pulse sweep you defined on the Pulse Settings screen
Level
Pulse Train sweep type only; the amplitude current or voltage from zero (not
from the bias level):
• Current: -10.5 A to 10.5 A
•
Voltage: -105 V to 105 V
Limit
The current or voltage limit for the defined pulse level:
• Current: 10 nA to 10.5 A
•
Voltage: 2 mV to 105 V
Off Time
The amount of time that the instrument stays at bias level after each pulse (in
seconds): 0 to 10,000 s
Pulse Type
The type of pulse sweep to create:
• Pulse Train
• Linear Sweep Points
• Linear Sweep Steps
•
Logarithmic Sweep
Start
Not available for the Pulse Train sweep type; the voltage or current source
level at which the pulse sweep starts:
• Current: -10.5 A to 10.5 A
•
Voltage: -105 V to 105 V
Step Size
Linear Sweep Steps sweep type only; the step size at which the source level
will change; step size must be greater than 0
