LTE-TDD Programming Commands
The following command is used to retrieve the measurement trace:
MEAS|READ| FETCh:LSEQuen cer:ACQuire{1.. .512}:ASTep{1.. .1000}:LTETdd:
PVT:TRACe
This command returns acquired I/Q trace data used in analysis step interval as a series of
comma-separated trace point values. The I values are listed in each pair, using 0 through even-indexed
values. The Q values are odd-indexed values. At most 2000 sample data can be returned (one sample
contains one I data and one Q data). If the actual number of samples exceeds 2000, then actual trace data
will be compressed/decimated to 2000 and be returned as the trace data.
Example command:
FETCh:LSEQ:ACQ1:ASTep1:LTETdd:PVT:TRACe?
16 Trace Sample Interval Result is a floating point number representing the time
between samples of compressed/decimated I/Q trace data which could be got by
trace query.
17 Number of Trace Samples Result is the number of data points in the
compressed/decimated I/Q trace data which could be got by trace query.
