[time-nuts] Re: Will a TADD-2 work with 50 MHz input?

[Erik Kaashoek]

Jim,
If you do have a tinyPFA or nanoVNA-H4 to convert to tinyPFA you can input
10 MHz in one input and 50 MHz in the other.
The 10 MHz must be a square wave and you set the measurement frequency to
50 MHz
For best results you may have to increase the 10 MHz input level to 0 dBm
