9.3.3.2 Send/Query Trace Data (Remote Command Only)

Allows trace data to be sent to the instrument or queried from the instrument. The

response to the query is a list of the amplitude points which comprise the requested

trace in the current Y Axis Unit of the instrument. The X Axis Unit is that of the

destination trace (for send) or the source trace (for query).

Remote

Command

Notes The TRACe[:DATA] command is of the form:

:TRACe:DATA <trace>,<data>

where <trace> can be one of the following parameters:

TRACE1, TRACE2, TRACE3, TRACE4, TRACE5, TRACE6

and where <data> can be

- ASCII data, which consists of a string of values separated by comma

- REAL or INTeger sent as a definite length block, with a header describing the data to follow

Couplings Sweep points will affect the amount of data

:FORMat:DATA describes the different types of data formats that can be used with trace data

Use :FORMat:BORDer to set the byte order

Query Trace Data

Remote

Command

Example Send five points to Trace 1. Assuming that :FORMat:DATA is set to ASCii, Y Axis Unit is set to dBm,

and sweep points is set to 5, this will result in Trace 1 consisting of the five points -1 dBm, -2 dBm, -3

dBm, -4 dBm, and -5 dBm:

:TRAC TRACE1,-1,-2,-3,-4,-5

Query the instrument for the contents of trace 2:

:TRAC? TRACE2

Compatibility

Notes

In X-Series, the legacy RAWTRACE,LLINE1,LLINE2 parameters for trace data query are no longer

available
