Description
The different trace data formats are as follows:
TDF P
XTDF
Holds trace data.

trace I3
Activates single-sweep

terfrequency
and span.
Rwm4zts trace data.
Transfer
trace data to array A, one
element at a time.
Loop prints out trace B data.
Prints out the results.
Description: TDF P is the real number format. An example of a trace element returned with
the real number format is 10.00
dB.
When querying the trace or marker value, the value is
returned using the amplitude unit set by
AUNITS
(for example, watts or
dBm).
Restrictions: The spectrum analyzer must be in log scale to use TDF l? To send the trace data
back to the spectrum analyzer, the data must be converted to measurement units.
How data is returned: The following table describes what is transferred when the trace data
format is set to P, but the
AUNITS
are changed. In every case, the trace data transfer is ended
by a carriage return, and a line feed with an EOI.
