Measurement Functions
Trigger Function
Trigger output delay time for pulsed sweep measurements.
When using an SMU as a pulse source, the 4155B/4156B can output edge triggers at
each pulse leading edge. Trigger output delay time (TRIG OUT DELAY) specifies
how much to delay the trigger after the leading edge. So, you set the trigger output
delay time to wait until the 4155B/4156B outputs a stable pulse peak value.
Available setting range for the trigger output delay time is:
Range: 0 to specified pulse width, maximum 32.7 ms
Resolution: 100
m
s
Trigger output delay time is shown as T1 in the following figure.
If you want the external instruments to make a measurement while the pulse peak
value is being forced, the specified T1 and pulse width must satisfy the following
equation:
pulse width > T1 + Tex
where, Tex means the measurement time.
