I'm still struggling with this…
I'm a bit confused about the output voltage of the GPSDO because the homepage states the following:
Both output signals square wave at 3.3V CMOS levels with 50 Ohms characteristic impedance.
Output power level (measured at 10MHz, fundamental power channel):
+13.3dBm, drive setting 32mA
+12.7dBm, drive setting 24mA
+11.4dBm, drive setting 16mA
+7.7dBm, drive setting 8mA
From my point of view these values are contradictory because CMOS voltage != dBm related voltage:
7.7dBm at 50 Ohms = 1.535V p-p
13.3dBm at 50 Ohms = 2.924V p-p
I can also measure with a oscilloscope an output voltage of ~3.3V p-p (no matter which drive setting).
Where is my mistake?
