Question

Difficulty: EasyOscilloscopes

Match each oscilloscope front-panel control or display feature on the left with its corresponding measurement function on the right.

  • Volts/Div controlSets the vertical scale factor to measure signal amplitude and peak-to-peak voltage
  • Time/Div controlSets the horizontal sweep rate to measure time duration, period, and signal frequency
  • Trigger controlStabilizes repetitive waveforms on the display screen to prevent scrolling or drifting
  • Graticule gridProvides calibrated division lines etched on the screen for accurate visual measurement

Answer

Volts/Div matches vertical scale (amplitude/voltage measurement), Time/Div matches horizontal sweep rate (period/frequency measurement), Trigger matches waveform stabilization, and Graticule grid matches the calibrated measurement overlay.
Each oscilloscope feature is mapped directly to its core operational role: the Volts/Div knob scales the vertical axis for voltage amplitude, Time/Div scales the horizontal axis for time intervals, the Trigger synchronizes the horizontal sweep for a stable trace, and the Graticule acts as the calibrated grid overlay.

Step-by-Step Solution

1
Identify the vertical axis control and its function
Volts/Div controls vertical scaling to measure voltage values such as peak or peak-to-peak amplitude.
Vertical displacement on an oscilloscope screen is directly proportional to signal voltage.
2
Identify the horizontal axis control and its function
Time/Div controls horizontal sweep time to measure period and calculate frequency (f=1Tf = \frac{1}{T}).
Horizontal displacement represents elapsed time across the screen.
3
Identify the synchronization mechanism
The Trigger control stabilizes the signal display.
Without proper triggering, the trace starts at random points of the cycle, causing the waveform to scroll continuously.
4
Identify the physical reference markings
The Graticule grid provides the reference divisions for counting units.
The graticule lines allow the operator to multiply division counts by the scale settings.
