Clipping distance is the difference to the signal clipping value. SNR is
measured in AD converter.
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 MEASURING...” 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.
