The last value on the display is signal power difference between I and Q branch. The
numbers are shown in 0.1dB accuracy. The error messages, ”OUT OF RANGE”, are
shown only if the SNR and/or amplitude difference values are not acceptable.
Signal/Noise radiobutton (ALT+S/ALT+N):
When buttons are pressed, the RX I and Q burst data is asked, text ”SIGNAL MEASUR-
ING...” or ”NOISE MEASURING...” will come to 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
display. When either signal or noise measurement results are received ”MEASURING”
text is removed and measurements are updated to 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.
