Press the Scope View key to view the scope. This key toggles between
the Standard view shown below, and Marker view, which enables
markers and marker calculations.
Standard View
Description:
Identifies the volt/div. or curr/div. setting. √ indicates the trace is on. Dashes
(----) indicate the trace is off. Select the trace and press Enter to turn it on or off.
The data bar represents all of the waveform data that has been collected. The
yellow part indicates the portion of the data that is visible on the display. The
black part represents the data that is not visible.
Voltage trace labels appear on the left side of the grid (V1 V2, V3, V4).
Current trace labels appear on the right side of the grid (I1, I2, I3, I4).
Power trace labels appear on the center of the grid (P1, P2, P3, P4).
If a portion of a trace is red, it means that portion of the trace is out of range.
Only Models N676xA and N678xA SMU can display power traces.
If you turn the voltage and current knobs, a pop-up
dialog will indicate the present output settings.
If you push the voltage and current knobs, a pop-
up dialog appears to allow the following actions:
Lock/Unlock the voltage or current knobs.
On Models N678xA, select a limit parameter to control or select limit tracking.
Indicates that the trace, V1 in this example, is out of view. Use the Vertical
Volt/Div knob or the Vertical Offset knob to bring the trace into view.
Push the Trigger Level knob to autoscale the traces so that all of them will
appear on the display. This will trigger a new measurement.
The ground reference of the trace. Ground references are offset so that they do
not overlap. The ground reference offset value is referenced to the horizontal
center line of the grid.
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 at the bottom right of the display.
