The frequency correction is made by the frequency offset calculated by the
arithmetic mean of every specified region’s frequency offset. Each frequency offset
is calculated by the least square method against the unwrapped phase of I/Q pair.
Sample Trace Data - Constant Envelope

Sample Trace Data - Not Constant Envelope
(See below for explanation of variables.)
<soffset>
Optional real number, in seconds for time-domain traces, and is a dimensionless
index 0 to Npoints – 1, for frequency-domain traces
Specifies the amount of data at the beginning of the trace that will be ignored
before the decimation process starts. It is the time or frequency change from the
start of the trace to the point where you want to start using the data. The default
value is zero
<length>
Optional real number, in seconds for time-domain traces, and is a dimensionless
index 0 to Npoints – 1, for frequency-domain traces
Defines how much data will be compressed into one value. This parameter has a
default value equal to the current trace length
<roffset>
Optional real number, in seconds for time-domain traces, and is a dimensionless
index 0 to Npoints – 1, for frequency-domain traces
