I believe this should make the 8600 a basic frequency counter. I get a real-time reading on the 8600 display that changes as I change the frequency on the 8601. This occurs when I have the scope button pushed in on the 8600. When I press the "CW Counter" button on the front of the 8600, I get a frozen readout of the RF frequency that does not change in real-time when I vary the frequency output of the 8601. If I go back to pressing the scope button, I get the real-time frequency read again.

Unfortunately, the 8600a is not a normal counter. It will not work that way. For it to measure frequency you must reconnect the auxiliary output of the generator. It communicated frequency and the counter input is I believe only able to count lower frequencies.
Please remake the connections as per the diagram and answer the sweep question. We can then proceed from there step by step.
