Can I Use the 1655xA Model with the 1655xD Model in a Master/Slave Setup?

No. The A and D models cannot be used together in a master/slave setup because of the differences in trace memory depth. Cards must have the exact same model number to work together in a master/slave configuration. However, they can still be placed in the same logic analysis system, that is, 16500B/C, 16700A, 16702A, etc., and run independently.
