11.17 TRACe|DATA subsystem
Instead of the command word TRACe, DATA can also be used. Traces are
used for summarizing data. Several predefined traces are available. Each one
is described below.
Result Traces: MTRACE, ITRACE
For the results, two predefined traces (MTRACE = Measurement Trace and
ITRACE = Information Trace) are available. They cannot be deleted.
MTRACE receives its data from the SENSe:FUNCtion block. All sensor
functions switched on deliver their measured values to the MTRACE where
they are stored. ITRACE receives its data from the SENSe:FREQuency block.
In addition to the current receiver frequency the corresponding channel
number is also stored. The start command to initiate measurement
(INITiate[:IMMediate]) clears the MTRACE (or ITRACE) data set.
Via the control instruction(TRAC:FEED:CONT), a condition can be defined
that selects the data to be written into the MTRACE or ITRACE. If the control
conditions of the two traces are identical, each TRACE value has a
corresponding information value in the ITRACE. When the maximum data set
length is attained, MTRACE and ITRACE are closed down. Any subsequent
data are thus lost.
In the status reporting system the state of this traces is available in the status
bits (see Section 9.2.1.6).
IF Panorama Trace: IFPAN
The command TRACe:FEED:CONTrol IFPAN, ALWays starts loading of the
IFPAN Trace. The command DISPlay:MENU IFPAN starts the IF panorama,
and the data levels are output. The spectrum length depends on the
bandwidth chosen. The current number of pixels can be queried by the
command TRACe:POINts? IFPAN
In the status reporting system the state of this traces is available in the status
bits (see Section 9.2.1.6).
