Error with demo circuits

Good Morning,

 I am getting in touch with you since we have recently acquired two demo circuits, in this case it would be the 890B model and the LTC2321 CUFD-16 ADC (1996A-B).

Following your instruction manual, we inject a sinusoidal signal of 10MHz and 2.5Vpp as clock signal to input J1, on the other hand, we inject another sinusoidal signal of 5MHz and 2Vpp in input J4.

Using PScope, the configuration we are using is the one you can see in the attached image:

We press the "collect" button and it throws us the error "please clock is on and verify Msps is set correctly.", And we cannot show the signal to be analyzed. Could you tell me what we are not doing correctly?
