The 5883H is an example of a ...Typically the sensitivity of the receiver is the RF signal level for which the measured BER is 5%. Though digital receiver sensitivity is specified and measured with just a single test signal, real-world receivers are impacted by a wide variety of signals. In testing and predicting receiver performance in these real-world situations, the ...A directional coupler is a measurement device that is inserted into the transmission line between an RF source—such as a signal generator, vector network analyzer, or transmitter—and a load. It measures both the RF power from the source to the load—the forward component—as well as the reflected component, power reflected back from the ...The receiver consists of a monopole antenna, an RF amplifier, a synthesizer for LO signals, an audio amplifier, and various mixers, IF amplifiers, and filters. The input signal to the receiver is in the frequency range of 20-470 MHz; the output signal is an audio signal from 0 to 8 kHz. A detector and a variable attenuator are used for ....
