Narrative:
[We were] descending to 10;000 ft approaching tenco. Norcal called out climbing traffic to our north--then gave us two vector headings in quick succession. We then got a TA at approximately 10;200 ft followed by a descend RA--followed immediately by a climb RA. I disconnected the autopilot and flew the escape maneuver. At about 10;400 ft we got an 'adjust vertical speed' RA followed quickly at about 10;500 ft by the 'clear of conflict' advisory. I never saw the traffic but believe I saw an altitude difference of -200 ft on the nd.
