TRACE The MKR

TRACE softkey places the marker on a new trace. The trace is selected
via a data entry field. Only those traces can be selected which are visible on the
screen in the same window.
The function of the softkey is identical to the MKR

TRACE softkey in the MKR and
MKR-> menu.
Example:
Three traces are presented on the screen. The marker is always on Trace 1 on
switching on.
[ MKR ->TRACE] "2"
The marker jumps to Trace 2 but remains on the previous frequency or time.
[ MKR ->TRACE] "3"
The marker jumps to Trace 3.
Remote command:

4.5.10 Selection and Setting of Traces – TRACE Key
The R&S ESU is capable of displaying up to three different traces at a time in a dia-
gram. A displayed trace consists of a maximum of 625 pixels on the horizontal axis
(frequency or time). If more measured values than pixels are available, several mea-
sured values are combined in one pixel.
The R&S ESU stores up to two million measured values per trace for a frequency
scan and up to two million measured values per trace for a scan on a fixed fre-
quency (time domain) in its internal memory.
The traces are selected using the SELECT TRACE softkey in the menu of the
TRACE key .
The traces can individually be activated for a measurement or frozen after comple-
tion of a measurement. Traces that are not activated are blanked.
The display mode can be selected for each trace. Traces can be overwritten in each
measurement (CLEAR/WRITE mode), averaged over several measurements
(AVERAGE mode), or a maximum or minimum value can be determined from sev-
eral measurements and displayed (MAX HOLD or MIN HOLD).
Individual detectors can be selected for the various traces. The max peak detector
and min peak detector display the maximum and minimum value of the level within a
pixel. The rms detector displays the power (rms value) of the measured values
within a pixel, the average detector the average value.
The quasipeak detector yields the level weighted to CISPR 16.
