Lesson 2 - Core Lab Tools

Which instrument is most suitable for measuring the resistance of a component?

• Oscilloscope

• Multimeter

• Function Generator

• PSU

What does a PSU provide in a lab?

• AC test signals

• Logic level outputs

• Regulated DC voltage

• Frequency analysis

Which control on an oscilloscope adjusts the vertical scale?

• Time/div

• Volts/div

• Trigger

• AC/DC coupling

A function generator is used to:

• Display signals on screen

• Provide stable DC power

• Produce test signals like sine or square waves

• Measure current in a circuit

What happens if the oscilloscope trigger is not set correctly?

• Signal disappears

• Signal rolls or appears unstable

• Multimeter fuse blows

• PSU switches off

On a digital multimeter, the black lead should be connected to:

• COM socket

• V socket

• Ω socket

• mA socket

Which probe setting reduces loading on a circuit being measured?

• ×1

• ×10

• AC

• Ground

If a function generator is set to 1 kHz, what is the period (T)?

• 1 ms

• 10 ms

• 100 ms

• 0.1 ms

Which tool is used to capture multiple digital signals for timing analysis?

• Logic Probe

• Logic Analyser

• Oscilloscope

• Spectrum Analyser

A spectrum analyser shows signals in terms of:

• Voltage vs Time

• Frequency vs Amplitude

• Current vs Voltage

• Resistance vs Time
