232User Manual 1178.3834.02 ─ 05
The available frequency/power range depends on the frequency/power range of the
generator and the used power sensor.
The range for the start time is -1s to +1s. Value 0 defines the trigger point. By choosing
a negative time value, the trace can be shifted in the diagram.
It is possible, that the measurement cannot be performed over the complete time range
because of limitations due to sensor settings. In this case, the R&S SMA100B gener-
ates an error message.
If you change this value for a finished single measurement, only the scaling of the x-
axis changes. This way, you can zoom the trace. However, for subsequent measure-
ments, the measurement range is changed according to the new setting.
If you change this value during a continuous measurement, only the scaling of the x-
axis changes for measurement cycles that have been triggered before the change. For
subsequent measurement cycles, the measurement range changes according to the
new setting.

Max - Power Analysis
Sets the maximum frequency/power/time of the measurement.
The available frequency/power range depends on the frequency/power range of the
instrument and the used power sensor.
The range for the stop time is 0 s to 2 s. Value 0 defines the trigger point.
It is possible, that the measurement cannot be performed over the complete time range
because of limitations due to sensor settings. In this case, an error message is output.
If you change this value for a finished single measurement, only the scaling of the x-
axis changes. This way, you can zoom the trace. However, for subsequent measure-
ments the measurement range is changed according to the new setting.
If you change this value during a continuous measurement, only the scaling of the x-
axis changes for measurement cycles that have been triggered before the change. For

Steps - Power Analysis
Sets the number of steps for the sweep. The number of measured points is steps + 1.
The number of steps is one of the parameters that define the measurement speed. The
higher the number of steps, the longer the measurement takes (frequency and power
mode).
