R&S ESU Series - Selection and Setting of Traces - TRACE Key

Operating Manual 1302.6163.12 - 03 4.129
R&S ESU Instrument Functions
Analyzer Mode
Fig. 4.6 Setting GATE DELAY and GATE LENGTH in time domain by means of lines GD and GL
On quitting the GATE SETTINGS menu, R&S ESU returns to the previous screen.
DELAY COMP
ON | OFF
The DELAY COMP ON/OFF softkey enables the filter group delay compensation for
the external trigger and IF power trigger. If a bursted signal is analyzed in zero span
and the delay compensation is on, a change of the RBW will not change the rising
slope of the signal.
Default is OFF.
Remote command: TRIG:HOLD:ADJ:AUTO ON|OFF
4.8.7 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 trace consists of a maximum of 625 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.
