WebbThe amplitude of the RF signal is now the 12 dB SINAD sensitivity of the receiver. On a 450 MHz MaxTrac, the SINAD sensitivity is usually around -120 dBm (around 0.22 microvolts). Receiver Performance: I used a 450 MHz MaxTrac as my subject receiver because it was the nearest radio to my test bench. I used the handset output signal on the MIC jack.
WebbThis Pin is the receiver sensitivity of the Device Under Test (DUT). Refer RF Receiver Sensitivity test and measurement setup . Receiver Selectivity- It refers wireless receiver's capability to detect and decode desired signal in the presence of other unwanted interfering signals. In the other way, selectivity of the receiver means how well a ... 大分杵築テラスWebbFollowing test procedure is followed for receiver sensitivity measurement: Do the test setup as shown in the figure.
