Fractional Spurs (Internal Divide by 2 Enabled)
Spur at 250 kHz offset at a frequency of
555.125 MHz is –92.5 dBc. Since this
mode uses the divide by 2 mode, the
channel spacing here is actually 125
kHz.
The spur at 125 kHz could be
completely eliminated changing the
fractional denominator.
Spur at 250 kHz offset for a frequency of
575.125 MHz is -83.4 dBc.
Spur at 250 kHz offset for a frequency of
590.125 MHz is –83.6 dBc.
