Meas Off (Spectrum Analyzer) Measurement
Chan STD
"Chan STD" allows you to select a specific Radio Standard for the measurement.
Depending on the Standard selected, the Channel parameters (Channel/Start Freq/Stop
Freq) will be set to the appropriate values associated to the standard. Similarly, the Start
Frequency, Center Frequency/Span, Stop Frequency values displayed on the X Axis of the
graph will be updated accordingly.
The table below shows the coupling between Channel number and Center Frequency for
the GSM Standards:
