MTRACE (Trace Data from saved Data Set)
This command reads out the trace data in alphanumeric format from a previously saved data set.
The current unit is used for the values. A trace consists of 301 data values. If the Auto Peak detector is
used, both max and min values are returned (602 values: 301 min values then 301 max values).
Example:
get<cr>
0<cr>
mtrace,mydata.001<cr>
‘readout trace data from data set “mydata.001”
0<cr>
‘responds parameter ok
-103.22,-106.88,-96.27,.....
Note:
In Tracking Generator with measurement modes Smith Chart, Phase or Vector Magnitude
the trace will also be sent in unit degrees. First 301 magnitude values and 301 additional
phase values. Phase values are wrapped or unwrapped depending on Wrapphase.
MTRACEBIN (Trace Data Binary from saved Data Set)
This command reads out the trace data in binary format from a previously saved data set..
Each sample consists of 4 bytes with the LSB send first. The 4 bytes represent the measured power in
the current unit. The sample values are multiplied to provide the highest resolution possible.

A trace consists of 301 samples. If the Auto Peak detector is used, both Max and Min values are
returned (602 samples: 301 min values then 301 max values).
