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
