The difference between the carrier frequency of an fm signal and its maximum frequency excursion when modulated. A-4. Amplitude versus frequency (the frequency domain of the signals). A-5. The same amount of intelligence can be transmitted with one-sixth of the output power with less than one-half the bandwidth. A-6. Both the bandwidth and the number of significant sidebands increase. A-7. The ability of the analyzer to discriminate between display signals of slightly different frequencies. A-8. Both transmit a pulse and analyze the signal reflection. A-9. A Tdr will indicate the nature of and the distance to or location of any faults. A-10. To determine various characteristics of a component, piece of equipment, or system over its operational frequency range. A-11. Swr on the transmission line. A-12. You must ensure that power induced from any adjacent transmitting antennas does not damage your test equipment.
