 :TRACe<n>:UPDate:STATe
:TRACe[:DATA]
Syntax
:TRACe[:DATA]? TRACE1|TRACE2|TRACE3
Description
Queries the log data of the specified trace.
Parameter
Name
Type
Range
Default
--
Keyword
TRACE1|TRACE2|TRACE3
--
Remarks
If the filter for the specified range in the scan table is EMI filter and RBW is 1 MHz, and the trace detector
type is quasi peak, the query of the corresponding trace data returns -1.700000000e+02.
If the filter the filter for the specified range in the scan table is Gauss filter, and the trace detector type is
quasi peak, CISPR average, or RMS average, the query of the corresponding trace data returns
-1.700000000e+02.
Return Format
The query returns the data of the specified trace. The format of the returned data is determined by the
settings of the
:FORMat[:TRACe][:DATA] command.
Example
[1]
1. When the data format is ASCii,
The following query returns -1.390530e+01, -7.108871e+01, -7.089631e+01, -6.992984e+01,
-7.010770e+01, ……
:TRACe:DATA? TRACE1.
2. When the data format is REAL[,32],
The following query returns
#90000032041111111111111111111111111110011111111111111111111111111111011101111111
11111111111111111111010011…….
Note: The PC software converts the returned binary data to ASCII format. Therefore, if you use the PC
software to perform the query command, the returned value is displayed as a messy code.
:TRACe:DATA? TRACE2
Note
[1]
: The two examples in this page take sending 801 points as an example, and the query returns 801
points. Due to the limited space, the subsequent data are omitted. In addition, the returned values of the
above examples are obtained when the system stops sweeping the trace.
