Manual Sweep (Measurement at a Specified Point)

Manual Sweep (Measurement at a Specified Point)
In the normal sweep mode, the Agilent 4294A performs measurement by automatically
changing the measurement point in response to triggering. When the set of measurements
performed is as many as the number of points, this is regarded as one sweep. On the other
hand, in the manual sweep mode the Agilent 4294A does not automatically change
measurement points (sweep), and the measurement at a single point specified by the user is
regarded as one sweep. Since the measurement point can be arbitrarily specified by the
user, this function can be called a user-defined manual sweep. The Agilent 4294A will
continue measurement (sweep) at the same point unless it is changed by the user. Follow
the steps below to execute the manual sweep.

generated.
The number of points can be commonly set to traces A and B.
