A method of and apparatus for balancing rotating machinery (20) involves the transient acquisition of transient data (100) over the operational speed range of the engine being analyzed. A spectrum of the transient data is acquired using a real time spectrum analyzer (7) capturing an RPM triggered waterfall (34, 38). Further, a computer calculates a one shot balance solution. The balance solution (44) is shown on a video display screen (850) and includes the suggested solution to the balance problem based on the acquired data and generic sensitivity coefficients (46) and the predicted vibrational behavior of the proposed solution. By acquiring a second set of data, it can be verified whether the one shot balance solution remedied the balance problem. If a problem remains, the operator may calculate engine specific sensitivity coefficients based on at least two previous data acquisition runs. A new trim balance solution is then calculated based on the immediately previous run and the calculated engine specific sensitivity coefficients.
