I’m confused by the specs for the 10 MHz reference for the B205mini. In kb.ettus.com/B200/B210/B200mini/B205mini#Timing_Reference_Input, and in the schematics, the minimum level is specified as 0/1.8V minimum and the maximum 0/5V. The limits are also given as 10 dBm to 27 dBm.
27 dBm into a 50 ohm load translates to 5Vrms, 7.07 V peak, 14.15 Vpp. 10 dBm translates to 0.7 Vrms, 0.99 Vpeak, 2.00 Vpp. A 17 dB difference in power (between 27 dBm and 10 dBm) indicates a voltage ratio of about 7. What am I getting wrong, please? Thanks. Dave
