3-53. The triggered oscilloscope has which of
the following advantages over a basic
oscilloscope?
1. Better low-voltage input- handling
capability
2. Lower distortion of input signal
3. Both 1 and 2 above
4. Improved presentation stability
3-54. The TRIGGER and LEVEL controls are
used to synchronize the sweep generator
with what signal?
1. Input
2. Output
3. Vertical deflection rate
4. Horizontal deflection rate
3-55. The setting of what control establishes
the amplitude point of the input
waveform at which the displayed sweep
will begin?
1. TRIGGER LEVEL
2. TRIGGER SLOPE
3. AMPLITUDE
4. A delayed by B
