Averaging
Averaging is a noise reduction technique. This calculation involves
taking the complex exponential average of several consecutive sweeps.
This averaging calculation is different than the System Bandwidth
setting. System Bandwidth uses digital filtering, applying noise
reduction to the measured data before it is stored into the Raw Data
Arrays.
Corrected Data Arrays
The combined results of the ratio, error correction and averaging
operations are stored in the corrected data arrays as complex number
pairs. These arrays are accessible via GPIB and referenced as
CH[1|2]SDATA.
Corrected Memory Arrays
If the Data−>Mem or Normalize operations are performed, the corrected
data arrays are copied into the corrected memory arrays. These arrays
are accessible via GPIB and referenced as CH[1|2]SMEM.
