Spurious and Phase Noise
RF Explorer Signal Generator Combo uses a low noise signal source and low noise independent voltage
regulators to provide a reduced phase noise output signal.
Below table shows typical values measured at -20dBm output power. These values can slightly increase or
decrease at different power levels.
CW Frequency
Phase Noise @ 1KHz
Phase Noise @ 100KHz
Phase Noise @ 1MHz
2MHz
-93 dBc/Hz
-105 dBc/Hz
-122 dBc/Hz
1GHz
-96 dBc/Hz
-108 dBc/Hz
-128 dBc/Hz
5.8GHz
-74 dBc/Hz
-90 dBc/Hz
-115 dBc/Hz
Spurious signals are created by the internal signal source at multiples of the frequency divider and, even
though they are filtered, some residues signals may display at 1GHz CW output signal.
Spur @ 16KHz
Spur @ 32KHz
Spur @ 4MHz
Spur @ 8MHz
-52 dBc
-72 dBc
-55 dBc
-68 dBc
