2. Data*Mem
Multiply the measured data by a memory trace.
3. Data-Mem
Subtract a memory trace from the measured data. This function can be used, for example, to subtract a
vector error that has been measured and stored (e.g., directivity) from data subsequently measured on
a device.
4. Data+Mem
Add the measured data and the data in the memory trace.
5. Off
Turn off the math operations.
● "Data -> Mem" must be performed first to select math operations.
● Trace math operations are mutually exclusive, that is, when a math function is applied to a trace,
the last selected math function will be turned off.
3.3.2.7 Average
Turn on or off the average function of traces, and set the average times.
More averages can reduce the noise and the influence of other random signals; thus highlighting the
stable signal characteristics. The larger the averages times is, the smoother the trace will be.

3.3.3 Sweep
3.3.3.1 Points
The number of points is the number of data items collected in one sweep.
● To obtain a higher trace resolution against the stimulus value, choose a larger value for number of
points.
● To obtain higher throughput, keep the number of points to a smaller value within an allowable trace
resolution.
