Explanation
On a Lab Scope, voltage is measured vertically and time is measured horizontally. This means that the voltage values are represented on the vertical axis, while the time values are represented on the horizontal axis. This allows for a clear and organized representation of the relationship between voltage and time in a graphical format.

Explanation
Ford's EEC 5 calculates 1.5 million calculations per second.

Explanation
A DMM (Digital Multi Meter) is a handheld device used to measure electrical quantities such as voltage, current, and resistance. It has a display rate of 4 times per second, meaning that it updates the measurements on its display 4 times every second. This allows for real-time monitoring and quick measurement readings.

Explanation
A voltmeter is a device used to measure the voltage of an electrical circuit. It is designed to provide accurate and stable readings, so it should not display signal glitches. Glitches are sudden and temporary changes in the signal, which can cause inaccurate readings. Therefore, the correct answer is false.

Explanation
The voltage of an electronic signal at any point in time is referred to as its amplitude. Amplitude represents the maximum value or intensity of the signal, indicating the strength or magnitude of the voltage. It is a measure of how high or low the signal reaches from its baseline.

Explanation
Square signals, also known as square wave signals, are a type of digital signal. Digital signals are characterized by discrete levels or states, typically represented by binary values of 0 and 1. Square signals have a distinct pattern where the signal rapidly alternates between high and low states, resulting in a square waveform. This type of signal is commonly used in digital electronics and communication systems to represent information in a binary format. Therefore, the correct answer is Digital Signals.

Explanation
The explanation for the given correct answer is that slope refers to the steepness or incline of a line. In the context of the question, the slope represents the direction at which the trace begins. Therefore, it is true that slope indicates the direction of the trace's starting point.

Explanation
The given statement is false. 19X speed is not usually for engine speed. The term "19X speed" is not commonly used to refer to engine speed. It is unclear what the term actually represents, as it is not a standard unit of measurement or a commonly used expression in relation to engines. Therefore, the statement is incorrect.

Explanation
The 3x signal is commonly used for coil pack identification. This signal refers to the number of pulses generated by the ignition module for each revolution of the crankshaft. By analyzing these pulses, the engine control unit can determine the firing order and timing for the ignition coils. This information is crucial for proper engine operation and ensures that each cylinder receives the appropriate spark at the correct time. Therefore, the statement is true.
