Table 11-21: Return values for TRACE1 to TRACE6 parameter
The trace data consists of a list of power levels that have been measured. The number of power levels in
the list depends on the currently selected number of sweep points. The unit depends on the measurement
and on the unit you have currently set.
If you are measuring with the auto peak detector, the command returns positive peak values only.
If you are working with the "Real/Imag (I/Q)" result display in I/Q Analyzer mode, the command returns two
values for each trace point, first the real parts of the signal, then the imaginary parts (I
1
,...,I
n
, Q
1
,...,Q
n
).
For SEM or Spurious Emission measurement results, the x-values should be queried as well, as they are
not equi-distant (see
TRACe<n>[:DATA]:X?
on page 856).
Table 11-22: Return values for LIST parameter
For every measurement range you have defined (range 1...n), the command returns eight values in the fol-
lowing order.
<No>,<StartFreq>,<StopFreq>,<RBW>,<PeakFreq>,<PowerAbs>,<PowerRel>,<PowerDelta>,<Limit-
Check>,<Unused1>,<Unused2>
●
<No>: range number
●
<StartFreq>,<StopFreq>: start and stop frequency of the range
●
<RBW>: resolution bandwidth
●
<PeakFreq>: frequency of the peak in a range
●
<PowerAbs>: absolute power of the peak in dBm
●
<PowerRel>: power of the peak in relation to the channel power in dBc
●
<PowerDelta>: distance from the peak to the limit line in dB, positive values indicate a failed limit
check
●
<LimitCheck>: state of the limit check (0 = PASS, 1 = FAIL)
●
<Unused1>,<Unused2>: reserved (0.0)
