Radio (Receiver)
Radio Type
Select the receiver radio button to create a receiver.
Antenna
From the antenna drop-down-list, select the antenna the radio is linked to.
Duty Cycle
Specify the duty cycle percentage.
Carrier Frequency
Specify the carrier frequency for the transmitter.
Spectrum Mask
Create a spectrum mask table by selecting the table button and importing the frequency delta and power values.
Necessary Bandwidth
Enter the necessary bandwidth. The necessary bandwidth is defined as the width of the frequency band which is just sufficient to ensure the transmission of information at the rate and with the quality required under specified conditions.
IF Bandwidth
Specify the intermediate frequency (IF) bandwidth. The range of frequencies centered around the IF frequency. A narrower IF bandwidth increases resolution and could lower the noise of a radio but could increase processing time.
Local Oscillator
Select from the drop-down list if the local oscillator is under, above or changing.
1st IF Frequency
Enter the value of the 1st intermediate frequency.
Impedance
Specify the impedance of the receiver by default it is 50 Ohm.
Sensitivity
Specify the minimum signal power in dBm which the receiver can detect a signal.
Processing Gain
Enter the value of the processing gain in dB. For direct sequence spread spectrum type of receivers, the processing gain is entered. Interfering signals are independent of the wanted signal, thus allowing the signal-to-interference ratio after de-spreading to be determined by adding the processing gain to the calculated signal-to-interference ratio before de-spreading.
Required S/I
Enter a value for the required signal to interference ratio in dB for the receiver.
Required S/N
Enter a value in dB for the required signal to noise ratio of the receiver.
Noise Figure
Enter a value for the noise figure in dB of the receiver.
Pulse Width
Enter a value of the pulse width in seconds for the receiver.
IM Attenuation
Specify the intermodulation (IM) attenuation for the second and third order components.
IF Attenuation
Enter a value in dB for the intermediate frequency attenuation. The loss of signal strength as the signal moves through the receiver at the IF frequency.
Image Frequency Attenuation
Enter a value in dB for the image frequency attenuation.
Blocking Level
Enter a value for the receiver blocking level in dBm.
