4.5.18 TRACe subsystem

Traces are used for summarizing data. The following traces are available:
Result trace:
For the results, two predefined traces (MTRACE = Measurement Trace and ITRACE
= Information Trace)are available. They cannot be deleted.
Via the control instruction, a condition can be defined which can preselect 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.
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.
IF Panorama Trace IFPAN
If the hardware option EB200SU (IF panorama) is installed, spectrum data can be queried via
Trace IFPAN.
The command
TRACe:FEED:CONTrol IFPAN, ALWays
starts loading of the IFPAN Trace. The command
DISPlay:MENU IFPAN
starts the IF panorama.
The data will be output in a raw form, ie like they are calculated by the DSP. The spectrum length
depends on the bandwidth chosen and will be between 770 and 1230 pixels. The current number
of pixels can be queried by the command
TRACe:POINts? IFPAN
