Which device is described as displaying the received video signal with two horizontal sweeps?

• A. Oscilloscope
• B. Pulse Analyser Indicator
• C. Spectrum Analyzer
• D. Multimeter

Answer: (B)

Understanding how video timing is analyzed in traditional RF/video gear hinges on a display that shows pulse timing clearly. A pulse analyser indicator is designed to present the received video signal with two horizontal sweeps, so you can observe how the timing of the pulses (the sync portion) lines up with the actual video content. This dual-sweep view makes it easy to verify that the synchronization intervals and the video levels occur when they’re supposed to, which is essential for proper video reception and alignment. Other instruments serve different purposes. An oscilloscope is a versatile time-domain instrument and can display waveforms, sometimes on two traces, but it isn’t described as specifically presenting two horizontal sweeps for video timing. A spectrum analyzer shows frequency components rather than time-domain video timing, and a multimeter measures basic electrical quantities rather than signal timing.
