Symbol/Field Description
7 Trigger Level Shows the location of the voltage or current trigger level and output. In this example, the voltage
trigger level of output 2 is shown. The trigger source and amplitude are shown atthe bottom right
of the display.
8 Trigger Indicator Shows the position of the trigger with respect to the waveform. In the figure, the trigger is offsetto
the left of the original point. The trigger point corresponds to the offset reference when the offset
is zero.
9 Scope Status
Range
Indicates whether the scope is Running, Stopped, or Waiting for a trigger.
Range indicates the measurement range setting of the selected trace. If the range field is red, it
means that portions of the selected trace are out of range.
10 Time
Time/Div.
Indicates the time from the trigger point indicator to the vertical center line of the grid. Negative
values indicate the center line is to the left of the trigger point. Positive values indicatethe center
line is to the right of the trigger point. Use the front panel Horizontal Offset knob to adjust the
trigger point.
Time/Div. identifies the horizontal time-base setting. This can be adjusted using the front panel
Horizontal Time/Div knob.
11 Horizontal Reference Indicates the horizontal reference. In the figure, the reference is centered. Change the reference
justification in the Scope Horizontal Properties window.
12 Trigger Source
Amplitude
In the figure, the trigger source is a voltage level on output 2.
Up trigger indicates the measurement will be triggered on the up-slope (positive).
Down trigger indicates the measurement will be triggered on the down-slope (negative).
If the trigger source is setto a voltage or current level, the amplitude of the trigger level is
indicated below the trigger source. In the figure, the voltage trigger level is setto 4.5 V.
13 Trigger Mode
Sample Rate
Indicates the trigger mode (Auto, Single, or Triggered).
The indicated scope sample rate is based on the horizontal time/div. setting. When the time/div.
setting is less than 20 ms/division, the scope will sample at its fastest rate, depending on the
number of traces selected:
1 trace(Model N678xA SMU only): 5.12 microseconds
1 to 2 traces (all modules): 10.24 microseconds
3 to 4 traces (all modules): 20.48 microseconds
