Corresponding SCPI Command(s) Description/Comments
Controls trace data input or output.
Transfers the trace data from the
controller to the instrument. The query
reads trace data out of the instrument. The
data is in a machine readable format that
the analyzer understands.
The data format for the command and
query is always TDF P.
The HP 8590-Series analyzer returns data
in the format: -57.71, -58.12, -56.87. The
HP ESA analyzer returns data in the
format: -5.46380000E+001,
-5.44410000E+001, -5.47590000E+001.
This is an example of IEEE NR3 numeric
response data.
Returns a non-negative integer that
indicates the total number of trace
registers available for SAVET and RCLT.
Creates a user-defined trace.
Turns the display of trace A, B, or C on or
off. It does this without clearing the trace
