MARKER
ZOOM The MARKER ZOOM softkey expands the area around MARKER 1. With the zoom
function, more details of the spectrum can be seen. The desired display range can
be defined in an entry window.
The following sweep is stopped at the position of the reference marker. The fre-
quency of the signal is counted and the measured frequency becomes the new cen-
ter frequency. The zoomed display range is then configured and the new settings
are used by R&S FSP for further measurements.
As long as switching to the new frequency display range has not yet taken place,
pressing the softkey will abort the procedure.
If MARKER 1 is not active when the softkey is pressed, it is automatically activated
and set to the highest peak in the window.
If an instrument setting is changed after selection of MARKER ZOOM , the function
is aborted.
The MARKER ZOOM softkey is only available in the frequency domain
(span > 0).
Remote command:
CALC:MARK1:FUNC:ZOOM 1kHz
ALL MARKER
OFF The ALL MARKER OFF softkey switches off all markers (reference and delta mark-
ers). It also switches off all functions and displays associated with the markers/delta
markers.
Remote command:
CALC:MARK:AOFF
MKR->TRACE The MKR->TRACE softkey places the active 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 this softkey is identical to that of the MKR->TRACE softkey in the
MKR-> menu (see “MKR->TRACE” on page 4.71 ).
[ MKR ] MARKER 1 is switched on ('1' highlighted in the softkey)
and set to the signal peak.
[ MARKER 2 ] MARKER 2 is switched on and automatically defined as the
delta marker ( DELTA is highlighted on MARKER NORM
DELTA softkey).
[ REFERENCE FIXED ] The frequency and level of MARKER 1 are a reference for
the delta marker.
[ CENTER : 200 MHz ] The center frequency is set to 200 MHz (= frequency of the
2nd harmonic). The reference level may have to be
reduced to see the 2nd harmonic from the noise. This does
not affect the reference level set with
REFERENCE FIXED .
[ MKR-> : PEAK ] The delta marker jumps to the 2nd harmonic of the signal.
The level spacing of the harmonic to the fundamental is dis-
played in the marker info field.
