TRACe Subsystem 
The TRACe subsystem controls access to the instruments internal trace memory. 
The following subsystem is included: 
• "TRACe:IQ Subsystem" on page 6.265 
Commands of the TRACe Subsystem 
– TRACe<1|2>[:DATA] 
– TRACe:COPY 
TRACe<1|2>[:DATA] 
 
This command transfers trace data from the control computer to the instrument, the query reads 
trace data out of the instrument. The transfer of trace data from the control computer to the 
instrument takes place by indicating the trace name and then the data to be transferred.  
For details on saving and recalling data refer to chapter 5 "Remote Control – Basics", section 
"MMEMory Subsystem". 
Parameter 
TRACE1 | TRACE2 | TRACE3 | TRACE4 | TRACE5 | TRACE6 | LIST | SPURious,<block> | 
<numeric_value> 
TRACE1, ... , TRACE6  trace memory to be read out 
<block> or <numeric_value>  data to be transferred 
 
query only: 
LIST  lists all results of the Spectrum Emission Mask and Spurious 
Emissions measurement 
SPURious  lists all peaks of the Spurious Emissions measurement 
 
Return values for trace data 
501 results are returned. The returned values are scaled in the current level unit. 
FORMat REAL,32 is used as format for binary transmission, and FORMat ASCii for ASCII 
transmission. For details on formats refer to "Formats for returned values: ASCII format and 
binary format" on page 6.300.  
Note:  With the auto peak detector, only positive peak values can be read out.
