Dialog mode: modal
The “Noise Sensitivity” dialog box has the following items:
Measurements group:
Clipping distance is the difference to the signal clipping value.
SNR is measured in an AD converter.
Sensitivity is a calculated value based on the measured SNR value.
The last value on the display is signal power difference between I and Q branch.
The numbers are shown in 0.1 dB accuracy. The error message, ”OUT OF RANGE”, is
shown only if the SNR and/or amplitude difference values are not acceptable.
Signal/Noise radio button (ALT+S/ALT+N):
When button is pressed, the RX I and Q burst data is asked, text ”SIGNAL MEASURING...”
or ”NOISE MEASURING...” appears in the measurement group window. The power level
value should be -92 dBm during signal measurement.
When signal data is received, distance to clipping signal level is shown as dBs on the dis-
play. When either signal or noise measurement results are received, the ”MEASURING”
text is removed and measurements are updated to the screen. When both measurements
(signal and noise) are done at least once, the signal-to-noise relation and difference are
also shown on the display.
When exit is made, the next selections are set to the values which were selected before
this adjustment.
-Active unit
-Operation mode
-AGC value
