OUTPUT SEQUENCE MODE OF SAMPLING
For a sampling measurement, you can set the output sequence to
sequential mode
or
simultaneous mode
. This field is displayed only when sampling mode is selected
on the CHANNELS: CHANNEL DEFINITION screen. If you select sequential
mode, OUTPUT SEQUENCE table determines the output order. If you select
simultaneous mode, all the units force at the same time.
TRIGGER SETUP
• ENABLE/DISABLE
ENABLE/DISABLE field defines whether the triggering function is used or not.
In this field, select:
• ENABLE secondary softkey to enable the triggering function.
• DISABLE secondary softkey to disable the triggering function.
• FUNCTION
FUNCTION field sets the triggering mode.
• Select TRIG OUT secondary softkey to enable the following functions:
• For a normal (non-pulse) sweep measurement, the 4155B/4156B outputs
an edge-trigger signal when a measurement starts for each step.
• For a pulsed sweep measurement, the 4155B/4156B outputs an
edge-trigger signal synchronized with the pulse leading edge.
• Select TRIG IN to enable the following function:
• Sweep measurement or sampling measurement starts when the
4155B/4156B receives a trigger signal from an external instrument.
• STEP DELAY
STEP DELAY field is displayed when you set staircase sweep measurement.
The step delay time is the time from when the trigger is output to when the next
step occurs. For details about setup delay time, refer to “Triggering an External
Instrument” in Chapter 3. When you set
TRIG IN
in the FUNCTION field, this
field has no meaning , so "
