Remarks
Spectrum analyzer must be in log scale to use TDF P. To send the
trace data back to the spectrum analyzer, the data must be
converted to measurement units.
Fastest format for trace data transfers. Use the A-block format
to
send data back to the spectrum analyzer.
Trace data preceded by
“#,
n
“A,” and a two-byte number. To use
the A-block format for sending data, you must provide the
number of data bytes.
Trace data preceded by
“#,
”
and “I.
”
This format is not
recommended for use with an RS-232 interface. Unlike using the
A-block format, you do not provide the number of data bytes
when sending data.
TDF M cannot be used to send trace data back to the spectrum
analyzer.
