GPScon just sets up a serial connection for sending SCPI commands to the device. If you know the serial parameters such as baud rate, parity, etc. you can connect to your device using something like PuTTY for example. I could connect to my Jackson-Labs GPSDO using a Python library known as pyvisa <

[time-nuts] Phase coherence with 2x GPSDO

2022-03-06 Thread Krishna Makhija
Hello, I am new to the whole precision time-keeping game (and to this mailing list) so I apologize in advance if my question is too naive or has been answered already in your mailing list. Is it possible to have two separate GPSDOs, each with their own antennas, be phase coherent to each other? I
