10 Mhz Reference Out

This is my 1st time using a GPDSO. I have verified the GPDSO is locked and the 10 MHz Reference signal is locked on the GPDSO as well. I decided to hook my oscilloscope to the 10MHz Reference out and look for the signal. I am using a 50 ohm bnc cable about 3' long. I found I don't see any signal at all on the port.

I assumed I would be able to see the reference clock output signal. I tested the setup using my Elecraft signal generator and had no issues seeing the 40 meter reference signal

I am curious to know if any one else has measured the 10Mhz reference signal out source.

    I think you need the optional Flex GPSDO unit installed in your 8600 to see anything at the 10M ref output port.

    The 10Mhz connector is only installed if the GPSDO is installed.

    Guys, I know you want to help. Apparently you did not read…

    I have verified the GPDSO is locked and the 10 MHz Reference signal is locked on the GPDSO as well.
