What is the output port signal level at 547.25 MHz if the input signal is 35.0 dBmV and the insertion loss is 1.4 dB?

What is the output port signal level at 547.25 MHz if the input signal is 35.0 dBmV and the insertion loss is 1.4 dB?

• A. 31.6 dBmV
• B. 33.6 dBmV
• C. 34.0 dBmV
• D. 30.0 dBmV

Answer: (B)

To determine the output port signal level when given the input signal and the insertion loss, you can subtract the insertion loss from the input signal level. In this scenario, the input signal is 35.0 dBmV. The insertion loss is 1.4 dB, which represents the signal level decrease resulting from the insertion of a device in the signal path. The calculation can be done as follows: 1. Start with the input signal level: 35.0 dBmV. 2. Subtract the insertion loss: 35.0 dBmV - 1.4 dB = 33.6 dBmV. This result, 33.6 dBmV, indicates the output port signal level after accounting for the insertion loss, making it the correct answer.
