6.20 TRACe Subsystem
The TRACe subsystem controls access to the instrument's internal trace memory.
6.20.1
General Trace Commands
TRACe[:DATA]
TRACE1 | TRACE2 | TRACE3 | SINGle | PHOLd | SCAN | STATus | FINAL1 | FINAL2
| FINAL3 | LIST | SPURious, <block> | <numeric_value>
This command transfers trace data from the control computer to the instrument, the query reads trace
data out of the instrument.
Programmiing trace data to the instrument is available in spectrum analyzer mode.
The numeric suffix at TRACe<1|2> selects the measurement window.
TRACE1
to
TRACE3
selects trace 1 to 3.
LIST
reads the peak list in the spurious measurement
(for
details on this measurement see page 220).
The suffix at TRACe<1|2> is irrelevant.
As results a list of <result of range 1>,< result of range 2>,..< result of range n> are
returned.
Every single range has following format:
<No>,<Start>,<Stop>,<rbw>,<freq>,<Levelabs>,<Levelrel>,<Delta>,
<Limitcheck>,<unused1>,<unused2>
Where:
If the FM demodulator (option R&S FS-K7) is active, only the displayed trace data
is read out and recalled. A portion of the measurement data that can be called by
means of a marker, however, is calculated from the raw measurement data. These
results are no longer available after recalling a trace; the associated queries gen-
erate a query error.
No
Range number
Start
Range start frequency
Stop
Range stop frequency
Rbw
Resolution bandwidth
Freq
Frequency of the peak in the range
Levelabs
Absolute peak power of the range in dBm
Levelrel
Reserved (0.0)
Delta
Delta of the peak power to the limit line in dB
Limitcheck
Limit check state (0 = PASSED, 1 = FAILED)
Unused1
Reserved (0.0)
Unused2
Reserved (0.0)
These values are defined via the [SENSe<1|2>:]LIST:RANGe<1...20> subsystem
FINAl lists the whole content of the peak list. Each peak element consists of
the following values
4 bytes: Frequency
4 bytes: Absolute level
4 bytes: Delta between absolute level and limit line value at given
frequency. If no limit line is active, the delta value is set to 0.0.
