Operating Manual EMI TEST RECEIVER ESIB7 - Rohde & Schwarz

Main Markers - Analyzer
ESIB
If a marker (or, delta marker) necessary for a marker function is not available, it will be automatically
checked whether or not the enabling of the corresponding marker is possible (see above). If this is not
the case, a warning is issued.
WARNING:
No trace active
The activation of the desired marker function is then not possible.
On the other hand, if the marker can be enabled, a peak search is automatically performed. Thereafter,
the desired marker function can be executed.
MARKER NORMAL menu:
ALL MARKER
OFF
The ALL MARKER OFF softkey switches off all markers (reference and delta
markers). Similarly, it switches off all functions and displays correlated with
the markers/delta markers (signal count, signal track, marker zoom, N dB
down, shape factor, marker list and marker info).
IEC/IEEE-bus command :CALCulate:MARKer:AOFF
SIGNAL
TRACK
After each sweep, the SIGNAL TRACK softkey starts a search for the
maximum signal level on the screen (PEAK SEARCH) and then sets the
center frequency to the frequency of this signal (MARKER ->CENTER).
If a threshold line is enabled, only signals above the threshold level are
considered. If no signal is over the threshold, the center frequency remains
constant until a signal is available which is over the threshold.
If no marker is switched to the active trace, the next unused marker is
automatically activated and positioned by the peak search routine.
In order to reduce the search range, it is possible to apply the SEARCH LIMIT
ON/OFF function (see section: "Search Functions"). If the center frequency is
changed, the position of the frequency line relative to the center frequency
remains the same, ie its absolute position is correspondingly changed.
The softkey is only available in the frequency domain (spectrum) display
mode (span > 0.)
