Instruments

Open Instruments in the dock. They work like bench tools. They are not saved in your circuit and are not part of your answer in a test.

MultimeterCopy Anchor Link

• Measures DC volts, AC volts (RMS), DC amps (clamp), AC amps (clamp, RMS) and Resistance of one part.
• It has red and black probe tips. Touch them to the points you want to measure.
• For current, use Clamp a part around a part.
• It works on parts that are locked in a question.

AC readings average over whole cycles, so they can take a few seconds to settle in a slow simulation.

Function generatorCopy Anchor Link

• Waveforms: Sine, Square, Triangle and Sawtooth.
• 50 Ω output.
• Frequency from 0.01 Hz to 1 MHz, 0 to 40 V peak-to-peak, and an offset of ±20 V.
• Press Output on to start it. It shows Output off when stopped.

Power supplyCopy Anchor Link

A DC supply with constant voltage (CV) and constant current (CC) modes. The voltage goes from 0.01 to 30 V and the current limit from 1 mA to 3 A. Press Output on to start it.

Bode plotCopy Anchor Link

Plots gain in dB and phase against frequency, with −3 dB markers. Press Run sweep to draw it. The first sweep loads the analysis engine, so it takes longer than later ones. Copy SPICE netlist copies your circuit as a netlist.
