A 1 kHz sine wave is displayed on the oscilloscope's screen in the following figure:
Figure 17
The various display elements are keyed by letters:
Element
Description
A
The cyan-colored symbol indicates that the USB connection is enabled and a flash
thumb drive is connected to the scope. The T in the orange polygon indicates the
location of the trigger point in the displayed waveform. The 800.0 us indicates that the
trigger point is displayed 800 µs before the center of the screen; this positioning was
gotten by turning the horizontal position control (19 in Figure 13).
B
This small graphic encapsulates information about the display. The horizontal yellow
line represents the time extent of the digitized waveform. The left and right green
square brackets indicate the part of the waveform that is shown on the screen. The T
indicates where the trigger point is on the screen. The inverted orange triangle
indicates the center of the screen.
C
This indicates the state of the scope. STOP means the RUN/STOP button has been
pushed to stop waveform acquisition. WAIT will be blinking when the scope is waiting
for a trigger event. Trig'd will be displayed when the scope is free-running and is being
triggered.
D
Shows the digital sampling rate. This number is changed by the timebase knob (8 in
Figure 16).
