R&S FSP
4.5.7 Selection and Setting of Traces – TRACE Key
The R&S FSP is capable of displaying up to three different traces at a time in a dia-
gram. A trace consists of a maximum of 501 pixels on the horizontal axis (frequency
or time). If more measured values than pixels are available, several measured val-
ues are combined in one pixel.
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 autopeak detector
displays maximum and minimum values connected by a vertical line. The max peak
detector and min peak detector display the maximum and minimum value of the
level within a pixel. The sample detector displays the instantaneous value of the
level at a pixel. The rms detector displays the power (rms value) of the measured
values within a pixel, the average detector the average value.

Selection of Trace Functions

The trace functions are subdivided as follows:
•
•
•
The TRACE key opens a menu offering the setting options for the selected trace.
In this menu, the mode of representing the measured data in the frequency or time
domain in the 501 pixels of the display is determined. Upon start of the measure-
ment, each trace can be displayed either completely new or based on the previous
results.
Traces can be displayed, blanked and copied. Traces can also be corrected with the
aid of mathematical functions.
The measurement detector for the individual display modes can be selected directly
by the user or set automatically by R&S FSP.
The default setting is trace 1 in the overwrite mode (CLEAR / WRITE), the other
traces 2 and 3 are switched off (BLANK).
The CLEAR/WRITE, MAX HOLD, MIN HOLD, AVERAGE, VIEW and BLANK soft-
keys are mutually exclusive selection keys.
