R&S ESU Instrument Functions
IF Spectrum Analysis Mode
SEARCH LIMIT
OFF
The SEARCH LIMIT OFF softkey disables all limits of the search range.
For further information refer to the descriptions in section “Receiver Mode” –
“SEARCH LIMIT OFF” on page 4.68.
MKR->TRACE
The MKR->TRACE softkey sets the active marker to a new trace.
For further information refer to the descriptions in section “Receiver Mode” –
“Change of Settings via Markers – MKR-> Key” on page 4.65.
MKR->CF
STEPSIZE
The MKR->CF STEPSIZE softkey sets the step size for the center frequency varia-
tion to the current marker frequency, and also sets step size adaptation to MANUAL.
CF STEPSIZE remains at this value until the center frequency entry mode in the
STEP menu is switched from MANUAL to AUTO again.
The MKR->CF STEPSIZE function is, above all, useful in the measurement of har-
monics with large dynamic range (narrow bandwidth and narrow span).
The softkey is not available in the time domain (span = 0 Hz).
Remote command: CALC:MARK:FUNC:CST
Example:
The harmonics levels of a CW carrier are to be measured at 100 MHz.
MIN
The MIN softkey sets the active marker/delta marker to the minimum of the corre-
sponding trace.
For further information refer to the descriptions in section “Receiver Mode” – “MIN”
on page 4.67.
NEXT MIN
The NEXT MIN softkey sets the active marker/delta marker to the next higher mini-
mum of the selected trace.
For further information refer to the descriptions in section “Receiver Mode” – “NEXT
MIN” on page 4.67.
[PRESET] R&S ESU is set to the default setting.
[CENTER: 100 MHz] R&S ESU sets the center frequency to 100 MHz. The span is
set to 200 MHz.
[SPAN: 1 MHz] The span is set to 1 MHz.
[MKR->] MARKER 1 is switched on and set to the maximum value of
the signal.
[NEXT] R&S ESU switches to the submenu.
[MKR->CF STEPSIZE] The step size of the center frequency setting equals the
marker frequency (100 MHz).
[CENTER] The center frequency entry mode is activated.
[Right key] The center frequency is set to 200 MHz. The first harmonic
of the test signal is displayed.
[MKR->: PEAK] The marker is set to the harmonic and the level of the latter is
output in the marker info field.
