Remote Control – Description of Commands
TRACe subsystem
:TRACe<1|2>:DATA
TRACE1 | TRACE2 | TRACE3 | LIST | SPURious | ABITstream | PWCDp |
CTABle, <block> | <numeric_value>
This command transfers trace data from the control computer to the instrument, the query reads trace
data out of the instrument.
The numeric suffix at TRACe<1|2> selects the measurement window.
Parameter:
TRACE1
to
TRACE3
selects trace 1 to 3.
LIST
reads the peak list in the spurious measurement
LIST EVALUATION
(for details on
this measurement see page 220) or in the spectrum emission mask measurement.
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:
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
(spurious measurement) or the [SENSe<1|2>:]ESPectrum:RANGe<1...20> subsystem
(spectrum emission mask measurement).
SPURious
reads the peak list in the spurious measurement. As results a list of
frequency, level and delta to limit line values is returned. A delta limit of +200dB
indicates no limit check is active.
ABITstream
reads the bit streams of all 15 slots one after another.
PWCDp
can be set for base station tests only if CODE PWR ABSOLUTE / RELATIVE ,
CHANNEL TABLE is selected for Trace 1. The pilot length is transmitted in addition to
the same five values as transmitted for TRACE1. The pilot length is specified in symbols.
Six
values
are
transmitted
for
each
assigned
channel:
<class>,<channel
number>,<absolute
level>,<relative
level>,<timing
offset>
(R&S
FS-K72)
or
<I/Q
mapping>
(R&S
FS-K73),
<pilot
length>,...
The pilot length is specified in bit.
CATABle
can be set only if CODE PWR ABSOLUTE / RELATIVE , CHANNEL TABLE is
selected for Trace 1. The same data as for TRACE1 are output. In addition, the pilot
length as the 6th value and active/inactive (1/0) as the 7th value are output for option
R&S FS-K72. With option R&S FS-K73, active/inactive (1/0) is output as the 6th value.
For R&S FS-K72 seven values are transmitted for each assigned channel:
<class>,<channel
number>,<absolute
level>,<relative
level>,<timing
offset>,
<pilot length>,<active/inactive>,...
R&S FS-K73
six
values
are
transmitted
for
each
assigned
channel:
