R&S FSQ Signal Analyzer - Rohde & Schwarz

On quitting the GATE SETTINGS menu, R&S FSQ returns to the previous screen.
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
4.5.7 Selection and Setting of Traces – TRACE Key
The R&S FSQ is capable of displaying up to three different traces at a time in a diagram.
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 values
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 completion
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 several
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.
