In field testing, which device is used to verify both continuity and signal levels on coaxial cable?

• A. Digital multimeter.
• B. Spectrum analyzer.
• C. Cable television tester.
• D. A handheld RF test meter or return-path test equipment to verify continuity and signal levels.

Answer: (D)

In field testing coax, you need an instrument that can confirm the physical path is intact and also show the actual RF signal levels. A handheld RF test meter is designed for on-site use and can perform a continuity check (to verify there are no opens or shorts in the conductor path) while also measuring the RF signal levels along the line. If the network uses a return path, return-path test equipment serves the same purpose for that direction, verifying continuity and measuring signal strength. Digital multimeters mainly measure DC resistance and aren’t suitable for RF levels; spectrum analyzers read RF spectra but aren’t typically used for quick continuity checks; and a general cable TV tester may not provide precise RF level readings. Hence, the best choice for verifying both continuity and signal levels in the field is a handheld RF test meter or return-path test equipment.
