When querying the results for eye diagrams, the results are merely superimposed
in the display. This means that the eye diagram result displays are the same as the
real/imag result display.
●
Polar diagrams
For polar diagrams, the command returns a pair of values for each trace point. The
first value is the real part, the second value the imaginary part. The number of
returned value pairs is the product of evaluation range length and points per sym-
bol for the Vector I/Q result display and the evaluation range length for the Constel-
lation I/Q result display.
The Constellation Frequency and Vector Frequency result display return one value
for each trace point on the y-axis.
●
Symbols
For the symbol table result diagrams, the command returns one value for each
number in the table. The number of returned values depends on the modulation
scheme you have selected.
If no parameter is specified, the command always returns the values in the decimal
format. If the parameter STRace is used, the format depends on the currently
defined symbol format (see
CALCulate<n>:FORMat
on page 247).
●
Eye diagram
●
For eye diagrams, the command returns one value for each sample. The number
of returned values is the product of evaluation range length and points per symbol.
●
Result Summary
For the Result Summary, the command returns all values listed in the result table
from top to bottom. The order of the results is as follows:
<result1_current>, <result1_mean>, <result1_peak>, <result1_stddev>,
<result1_95%ile>, <result2_current>, <result2_mean>, (...)
Empty cells in the table return nothing. The number of returned values depends on
the modulation scheme you have selected. PSK, MSK and QAM modulation
returns 53 values, FSK modulation returns 42 values. The unit of each value
depends on the particular result.
