TX GFSK Measurement Results
The measurement results for the GFSK are shown in
Figure
6 below.
Figure 16. TX GFSK results
After the setup has been completed, the measurement can be initiated by pressing either the
“Single” or “Continuous” buttons.
“Single” will capture and
analyze a single burst.
“Continuous” will capture and analyse a burst continuously until “Stop” is pr
essed
The output is:
•
“Status” shows the TX measurement status which can be “Idle” or “Running”
•
“TX Power” shows the TX power measured in dBm evaluated in the “Evaluation
Window”.
•
“Freq Offset” shows the frequency offset measured in kHz
of the signal evaluated in
the “Evaluation Window”. The modulated signal is estimated and subtracted, so that
the frequency offset will not be affected by unbalanced numbers of 0 and 1 in the
signal.
•
“Freq Deviation” shows the peak frequency deviation me
asured in kHz of the signal
within the
“E
valuation Window
